-## Public API validation
+### Public API
 
-It is critical to **NOT** make breaking changes to public APIs which have been
-released in stable builds. We also strive to keep a minimal public API surface.
-This repository is using
-[Microsoft.CodeAnalysis.PublicApiAnalyzers](https://github.com/dotnet/roslyn-analyzers/blob/main/src/PublicApiAnalyzers/PublicApiAnalyzers.Help.md)
-and [Package
-validation](https://learn.microsoft.com/dotnet/fundamentals/apicompat/package-validation/overview)
-to validate public APIs.
+It is critical to keep public API surface small and clean. This repository is
+using `Microsoft.CodeAnalysis.PublicApiAnalyzers` to validate the public APIs.
+This analyzer will check if you changed a public property/method so the change
+will be easily spotted in pull request. It will also ensure that OpenTelemetry
+doesn't expose APIs outside of the library primary concerns like a generic
+helper methods.
 
-* `Microsoft.CodeAnalysis.PublicApiAnalyzers` will validate public API
-  changes/additions against a set of "public API files" which capture the
-  shipped/unshipped public APIs. These files must be maintained manually (not
-  recommended) or by using tooling/code fixes built into the package (see below
-  for details).
+#### How to enable and configure
 
-  Public API files are also used to perform public API reviews by repo
-  approvers/maintainers before releasing stable builds.
+* Create a folder in your project called `.publicApi` with the frameworks that
+  as folders you target.
+* Create two files called `PublicAPI.Shipped.txt` and `PublicAPI.Unshipped.txt`
+   in each framework that you target.
+* Add the following lines to your csproj:
 
-* `Package validation` will validate public API changes/additions against
-  previously released NuGet packages.
+```xml
+<ItemGroup>
+  <AdditionalFiles Include=".publicApi\$(TargetFramework)\PublicAPI.Shipped.txt" />
+  <AdditionalFiles Include=".publicApi\$(TargetFramework)\PublicAPI.Unshipped.txt" />
+</ItemGroup>
+```
 
-  This is performed automatically by the build/CI
-  [package-validation](https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/.github/workflows/package-validation.yml)
-  workflow.
-
-  By default package validation is **NOT** run for local builds. To enable
-  package validation in local builds set the `EnablePackageValidation` property
-  to `true` in
-  [Common.prod.props](https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/build/Common.prod.props)
-  (please do not check in this change).
-
-### Working with Microsoft.CodeAnalysis.PublicApiAnalyzers
-
-#### Update public API files when writing code
-
-[IntelliSense](https://docs.microsoft.com/visualstudio/ide/using-intellisense)
-will [suggest
-modifications](https://github.com/dotnet/roslyn-analyzers/issues/3322#issuecomment-591031429)
-to the `PublicAPI.Unshipped.txt` file when you make changes. After reviewing
-these changes, ensure they are reflected across all targeted frameworks. You can
-do this by:
-
-* Using the "Fix all occurrences in Project" feature in Visual Studio.
-
-* Manually cycling through each framework using Visual Studio's target framework
-  dropdown (in the upper right corner) and applying the IntelliSense
-  suggestions.
-
-> [!IMPORTANT]
-> Do **NOT** modify `PublicAPI.Shipped.txt` files. New features and bug fixes
-  **SHOULD** only require changes to `PublicAPI.Unshipped.txt` files. If you
-  have to modify a "shipped" file it likely means you made a mistake and broke a
-  stable API. Typically only maintainers modify the `PublicAPI.Shipped.txt` file
-  while performing stable releases. If you need help reach out to an approver or
-  maintainer on Slack or open a draft PR.
-
-#### Enable public API validation in new projects
-
-1. If you are **NOT** using experimental APIs:
-   * If your API is the same across all target frameworks:
-     * You only need two files: `.publicApi/PublicAPI.Shipped.txt` and
-       `.publicApi/PublicAPI.Unshipped.txt`.
-   * If your APIs differ between target frameworks:
-     * Place the shared APIs in `.publicApi/PublicAPI.Shipped.txt` and

 * Make sure the PR title reflects the contribution.
 * Write a summary that helps understand the change.
 * Include usage examples in the summary, where applicable.
 * Include benchmarks (before/after) in the summary, for contributions that are
   performance enhancements.
-* We are open to bot generated PRs or AI/LLM assisted PRs. Actually, we are
-  using
-  [dependabot](https://docs.github.com/en/code-security/dependabot/dependabot-security-updates/configuring-dependabot-security-updates)
-  to automate the security updates. However, if you use bots to generate spam
-  PRs (e.g. incorrect, noisy, non-improvements, unintelligible, trying to sell
-  your product, etc.), we might close the PR right away with a warning, and if
-  you keep doing so, we might block your user account.

-
-### Digital signing
-
-Starting with the `1.10.0` release the DLLs included in the packages pushed to
-NuGet are digitally signed using [Sigstore](https://www.sigstore.dev/). Within
-each NuGet package the digital signature and its corresponding certificate file
-are placed alongside the shipped DLL(s) in the `/lib` folder. When a project
-targets multiple frameworks each target outputs a dedicated DLL and signing
-artifacts into a sub folder based on the
-[TFM](https://learn.microsoft.com/dotnet/standard/frameworks).
-
-The digitial signature and certificate files share the same name prefix as the
-DLL to ensure easy identification and association.
-
-To verify the integrity of a DLL inside a NuGet package use the
-[cosign](https://github.com/sigstore/cosign) tool from Sigstore:
-
-```bash
-cosign verify-blob \
-    --signature OpenTelemetry.dll-keyless.sig \
-    --certificate OpenTelemetry.dll-keyless.pem.cer \
-    --certificate-identity "https://github.com/open-telemetry/opentelemetry-dotnet/.github/workflows/publish-packages-1.0.yml@refs/tags/core-1.10.0-rc.1" \
-    --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
-    OpenTelemetry.dll
-```
-
-> [!NOTE]
-> A successful verification outputs `Verify OK`.
-
-For more verification options please refer to the [cosign
-documentation](https://github.com/sigstore/cosign/blob/main/doc/cosign_verify-blob.md).

-  and .NET Standard. This change may cause telemetry export to fail unless
-  appropriate adjustments are made. Explicitly setting OTLP/gRPC may result in a
-  `NotSupportedException` unless further configuration is applied. See
-  [#6209](https://github.com/open-telemetry/opentelemetry-dotnet/issues/6209) for
-  full details and mitigation guidance. [#6229](https://github.com/open-telemetry/opentelemetry-dotnet/pull/6229)

-## 1.11.1
-
-Release details: [1.11.1](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.11.1)
-
-* Fixed a bug preventing `OpenTelemetry.Exporter.OpenTelemetryProtocol` from
-  exporting telemetry on .NET Framework.
-
-## 1.11.0
-
-Release details: [1.11.0](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.11.0)
-
-* `OpenTelemetry.Exporter.OpenTelemetryProtocol` no longer depends on the
-  `Google.Protobuf`, `Grpc`, or `Grpc.Net.Client` packages. Serialization and
-  transmission of outgoing data is now performed manually to improve the overall
-  performance.
-
-## 1.10.0
-
-Release details: [1.10.0](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.10.0)
-
-* Bumped the package versions of `System.Diagnostic.DiagnosticSource` and other
-  Microsoft.Extensions.* packages to `9.0.0`.
-
-* Added support for new APIs introduced in `System.Diagnostics.DiagnosticSource`
-  `9.0.0`:
-
-  * [InstrumentAdvice<T>](https://learn.microsoft.com/dotnet/api/system.diagnostics.metrics.instrumentadvice-1)
-
-    For details see: [Explicit bucket histogram
-    aggregation](./docs/metrics/customizing-the-sdk/README.md#explicit-bucket-histogram-aggregation).
-
-  * [Gauge<T>](https://learn.microsoft.com/dotnet/api/system.diagnostics.metrics.gauge-1)
-
-  * [ActivitySource.Tags](https://learn.microsoft.com/dotnet/api/system.diagnostics.activitysource.tags)
-    (supported in OtlpExporter & ConsoleExporter)
-
-* Experimental features promoted to stable:
-
-  * `CardinalityLimit` can now be managed for individual metrics via the View
-    API. For details see: [Changing cardinality limit for a
-    Metric](./docs/metrics/customizing-the-sdk/README.md#changing-the-cardinality-limit-for-a-metric).
-
-  * The [overflow
-    attribute](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/sdk.md#overflow-attribute)
-    (`otel.metric.overflow`) behavior is now enabled by default. The
-    `OTEL_DOTNET_EXPERIMENTAL_METRICS_EMIT_OVERFLOW_ATTRIBUTE` environment
-    variable is no longer required. For details see: [Cardinality
-    Limits](./docs/metrics/README.md#cardinality-limits).
-
-  * The MetricPoint reclaim behavior is now enabled by default when Delta
-    aggregation temporality is used. The
-    `OTEL_DOTNET_EXPERIMENTAL_METRICS_RECLAIM_UNUSED_METRIC_POINTS` environment
-    variable is no longer required. For details see: [Cardinality
-    Limits](./docs/metrics/README.md#cardinality-limits).
-
-* Added `OpenTelemetrySdk.Create` API for configuring OpenTelemetry .NET signals
-  (logging, tracing, and metrics) via a single builder. This new API simplifies
-  bootstrap and teardown, and supports cross-cutting extensions targeting
-  `IOpenTelemetryBuilder`.
-
-* Removed out of support `net6.0` target and added `net9.0` target.
-
-## 1.9.0
-
-Release details: [1.9.0](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.9.0)
-
-* `Exemplars` are now part of the stable API! For details see: [customizing
-  exemplars
-  collection](https://github.com/open-telemetry/opentelemetry-dotnet/tree/main/docs/metrics/customizing-the-sdk#exemplars).
-
-* `WithLogging` is now part of the stable API! Logging, Metrics, and Tracing can
-  now all be configured using the `With` style and the builders finally have
-  parity in their APIs.
-
-## 1.8.0
-
-Release details: [1.8.0](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.8.0)
-
-* `TracerProvider` sampler can now be configured via the `OTEL_TRACES_SAMPLER` &
-  `OTEL_TRACES_SAMPLER_ARG` envvars.
-
-* A new `UseOtlpExporter` cross-cutting extension has been added to register the
-  `OtlpExporter` and enable all signals in a single call.
-
-* `exception.type`, `exception.message`, `exception.stacktrace` will now
-  automatically be included by the `OtlpLogExporter` when logging exceptions.
-  Previously an experimental environment variable had to be set.
-
-## 1.7.0
-
-Release details: [1.7.0](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.7.0)
-
-* Bumped the package versions of System.Diagnostic.DiagnosticSource and other
-  Microsoft.Extensions.* packages to `8.0.0`.
-
-* Added `net8.0` targets to all the components.
-
-* OTLP Exporter
-  * Updated to use `ILogger` `CategoryName` as the instrumentation scope for
-    logs.
-  * Added named options support for OTLP Log Exporter.
-  * Added support for instrumentation scope attributes in metrics.
-  * Added support under an experimental flag to emit log exception attributes.
-  * Added support under an experimental flag to emit log eventId and eventName.
-    attributes.
-
-* Added support for the
-  [IMetricsBuilder](https://learn.microsoft.com/dotnet/api/microsoft.extensions.diagnostics.metrics.imetricsbuilder)
-  API.
-
-* Added an experimental opt-in metrics feature to reclaim unused MetricPoints
-  which enables a higher number of unique dimension combinations to be emitted.
-  See [reclaim unused metric
-  points](https://github.com/open-telemetry/opentelemetry-dotnet/blob/32c64d04defb5c92d056fd8817638151168b10da/docs/metrics/README.md#cardinality-limits)

-# OpenTelemetry .NET SDK
-
-## Initialize the SDK
-
-There are two different common initialization styles supported by OpenTelemetry.
-
-### Initialize the SDK using a host
-
-Users building applications based on
-[Microsoft.Extensions.Hosting](https://www.nuget.org/packages/Microsoft.Extensions.Hosting)
-should utilize the
-[OpenTelemetry.Extensions.Hosting](../src/OpenTelemetry.Extensions.Hosting/README.md)
-package to initialize OpenTelemetry. This style provides a deep integration
-between the host infrastructure (`IServiceCollection`, `IServiceProvider`,
-`IConfiguration`, etc.) and OpenTelemetry.
-
-[AspNetCore](https://learn.microsoft.com/aspnet/core/fundamentals/host/web-host)
-applications are the most common to use the hosting model but there is also a
-[Generic Host](https://learn.microsoft.com/dotnet/core/extensions/generic-host)
-which may be used in console, service, and worker applications.
-
-> [!NOTE]
-> When using `OpenTelemetry.Extensions.Hosting` only a single pipeline will be
-> created for each configured signal (logging, metrics, and/or tracing). Users
-> who need more granular control can create additional pipelines using the
-> manual style below.
-
-First install the
-[OpenTelemetry.Extensions.Hosting](../src/OpenTelemetry.Extensions.Hosting/README.md)
-package.
-
-Second call the `AddOpenTelemetry` extension using the host
-`IServiceCollection`:
-
-```csharp
-var builder = WebApplication.CreateBuilder(args);
-
-// Clear the default logging providers added by the host
-builder.Logging.ClearProviders();
-
-// Initialize OpenTelemetry
-builder.Services.AddOpenTelemetry()
-    .ConfigureResource(resource => /* Resource configuration goes here */)
-    .WithLogging(logging => /* Logging configuration goes here */)
-    .WithMetrics(metrics => /* Metrics configuration goes here */)
-    .WithTracing(tracing => /* Tracing configuration goes here */));
-```
-
-> [!NOTE]
-> Calling `WithLogging` automatically registers the OpenTelemetry
-> `ILoggerProvider` and enables `ILogger` integration.
-
-### Initialize the SDK manually
-
-Users running on .NET Framework or running without a host may initialize
-OpenTelemetry manually.
-
-> [!IMPORTANT]
-> When initializing OpenTelemetry manually make sure to ALWAYS dispose the SDK
-> and/or providers when the application is shutting down. Disposing
-> OpenTelemetry gives the SDK a chance to flush any telemetry held in memory.
-> Skipping this step may result in data loss.
-
-First install the [OpenTelemetry SDK](../src/OpenTelemetry/README.md) package or
-an exporter package such as
-[OpenTelemetry.Exporter.OpenTelemetryProtocol](../src/OpenTelemetry.Exporter.OpenTelemetryProtocol/README.md).
-Exporter packages typically reference the SDK and will make it available via
-transitive reference.
-
-Second use one of the following initialization APIs (depending on the SDK
-version being used):
-
-#### Using 1.10.0 or newer
-
-The `OpenTelemetrySdk.Create` API can be used to initialize all signals off a
-single root builder and supports cross-cutting extensions such as
-`ConfigureResource` which configures a `Resource` to be used by all enabled
-signals. An `OpenTelemetrySdk` instance is returned which may be used to access
-providers for each signal. Calling `Dispose` on the returned instance will
-gracefully shutdown the SDK and flush any telemetry held in memory.
-
-> [!NOTE]
-> When calling `OpenTelemetrySdk.Create` a dedicated `IServiceCollection` and
-> `IServiceProvider` will be created for the SDK and shared by all signals. An
-> `IConfiguration` is created automatically from environment variables.
-
-```csharp
-using OpenTelemetry;
-
-var sdk = OpenTelemetrySdk.Create(builder => builder
-    .ConfigureResource(resource => /* Resource configuration goes here */)
-    .WithLogging(logging => /* Logging configuration goes here */)
-    .WithMetrics(metrics => /* Metrics configuration goes here */)
-    .WithTracing(tracing => /* Tracing configuration goes here */));
-
-// During application shutdown
-sdk.Dispose();
-```
-
-To obtain an `ILogger` instance for emitting logs when using the
-`OpenTelemetrySdk.Create` API call the `GetLoggerFactory` extension method using
-the returned `OpenTelemetrySdk` instance:
-
-```csharp
-var logger = sdk.GetLoggerFactory().CreateLogger<Program>();
-logger.LogInformation("Application started");
-```
-
-#### Using 1.9.0 or older
-
-The following shows how to create providers for each individual signal. Each
-provider is independent and must be managed and disposed explicitly. There is no
-mechanism using this style to perform cross-cutting actions across signals.
-
-```csharp
-using Microsoft.Extensions.Logging;
-using OpenTelemetry;
-
-var tracerProvider = Sdk.CreateTracerProviderBuilder()
-    /* Tracing configuration goes here */
-    .Build();
-
-var meterProvider = Sdk.CreateMeterProviderBuilder()
-    /* Metrics configuration goes here */
-    .Build();
-
-var loggerFactory = LoggerFactory.Create(builder => builder
-    .AddOpenTelemetry(options => /* Logging configuration goes here */));
-
-// During application shutdown
-tracerProvider.Dispose();
-meterProvider.Dispose();
-loggerFactory.Dispose();
-```

+# OpenTelemetry .NET Diagnostic: OTEL1003
+
+## Overview
+
+This is an Experimental API diagnostic covering the following API:
+
+* `MetricStreamConfiguration.CardinalityLimit.get`
+* `MetricStreamConfiguration.CardinalityLimit.set`
+
+Experimental APIs may be changed or removed in the future.
+
+## Details
+
+From the specification:
+
+> The cardinality limit for an aggregation is defined in one of three ways:
+>
+> 1. A view with criteria matching the instrument an aggregation is created for
+>    has an `aggregation_cardinality_limit` value defined for the stream, that
+>    value SHOULD be used.
+> 2. If there is no matching view, but the `MetricReader` defines a default
+>    cardinality limit value based on the instrument an aggregation is created
+>    for, that value SHOULD be used.
+> 3. If none of the previous values are defined, the default value of 2000
+>    SHOULD be used.
+
+We are exposing these APIs experimentally until the specification declares them
+stable.
+
+### Setting cardinality limit for a specific Metric via the View API
+
+The OpenTelemetry Specification defines the [cardinality
+limit](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/sdk.md#cardinality-limits)
+of a metric can be set by the matching view.
+
+```csharp
+using var meterProvider = Sdk.CreateMeterProviderBuilder()
+    .AddView(
+        instrumentName: "MyFruitCounter",
+        new MetricStreamConfiguration { CardinalityLimit = 10 })
+    .Build();
+```

-By default, the [OpenTelemetry
-Specification](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.14.0/specification/metrics/sdk.md#explicit-bucket-histogram-aggregation)
-defines explicit buckets (aka boundaries) for Histograms as: `[ 0, 5, 10, 25,
-50, 75, 100, 250, 500, 750, 1000, 2500, 5000, 7500, 10000 ]`.
+By default, the boundaries used for a Histogram are [`{ 0, 5, 10, 25, 50, 75,
+100, 250, 500, 750, 1000, 2500, 5000, 7500, 10000}`](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.14.0/specification/metrics/sdk.md#explicit-bucket-histogram-aggregation).
+Views can be used to provide custom boundaries for a Histogram. The measurements
+are then aggregated using the custom boundaries provided instead of the the
+default boundaries. This requires the use of
+`ExplicitBucketHistogramConfiguration`.
 
-###### Customizing explicit buckets when using histogram aggregation

-  If explicit buckets are not provided by either the View API or the Advice API
-  then the SDK defaults apply.
-
-* View API
-
-  Views can be used to provide custom explicit buckets for a Histogram. This
-  requires the use of `ExplicitBucketHistogramConfiguration`.
-
-  ```csharp
-   // Change Histogram boundaries to count measurements under the following buckets:
-   // (-inf, 10]
-   // (10, 20]
-   // (20, +inf)
-   .AddView(
-       instrumentName: "MyHistogram",
-       new ExplicitBucketHistogramConfiguration { Boundaries = new double[] { 10, 20 } })
-
-   // If you provide an empty `double` array as `Boundaries` to the `ExplicitBucketHistogramConfiguration`,
-   // the SDK will only export the sum, count, min and max for the measurements.
-   // There are no buckets exported in this case.
-   .AddView(
-       instrumentName: "MyHistogram",
-       new ExplicitBucketHistogramConfiguration { Boundaries = Array.Empty<double>() })
-  ```
-
-* Advice API
-
-  Starting with the `1.10.0` SDK, explicit buckets for a Histogram may be provided
-  by instrumentation authors when the instrument is created. This is generally
-  recommended to be used by library authors when the SDK defaults don't match the
-  required granularity for the histogram being emitted.
-
-  See: [Using Advice to customize Histogram
-  instruments](https://learn.microsoft.com/dotnet/core/diagnostics/metrics-instrumentation#using-advice-to-customize-histogram-instruments).
+    // If you provide an empty `double` array as `Boundaries` to the `ExplicitBucketHistogramConfiguration`,

-#### Produce multiple metrics from single instrument
-
-When an instrument matches multiple views, it can generate multiple metrics. For
-instance, if an instrument is matched by two different view configurations, it
-will result in two separate metrics being produced from that single instrument.
-Below is an example demonstrating how to leverage this capability to create two
-independent metrics from a single instrument. In this example, a histogram
-instrument is used to report measurements, and views are configured to produce
-two metrics : one aggregated using `ExplicitBucketHistogramConfiguration` and the
-other using `Base2ExponentialBucketHistogramConfiguration`.
-
-```csharp
-    var histogramWithMultipleAggregations = meter.CreateHistogram<long>("HistogramWithMultipleAggregations");
-
-    // Configure the Explicit Bucket Histogram aggregation with custom boundaries and new name.
-    .AddView(instrumentName: "HistogramWithMultipleAggregations", new ExplicitBucketHistogramConfiguration() { Boundaries = new double[] { 10, 20 }, Name = "MyHistogramWithExplicitHistogram" })
-
-    // Use Base2 Exponential Bucket Histogram aggregation and new name.
-    .AddView(instrumentName: "HistogramWithMultipleAggregations", new Base2ExponentialBucketHistogramConfiguration() { Name = "MyHistogramWithBase2ExponentialBucketHistogram" })
-
-    // Both views rename the metric to avoid name conflicts. However, in this case,
-    // renaming one would be sufficient.
-
-    // This measurement will be aggregated into two separate metrics.
-    histogramWithMultipleAggregations.Record(10, new("tag1", "value1"), new("tag2", "value2"));
-```
-
-When using views that produce multiple metrics from single instrument, it's
-crucial to rename the metric to prevent conflicts. In the event of conflict,
-OpenTelemetry will emit an internal warning but will still export both metrics.
-The impact of this behavior depends on the backend or receiver being used. You
-can refer to [OpenTelemetry's
-specification](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/data-model.md#opentelemetry-protocol-data-model-consumer-recommendations)
-for more details.
-
-Below example is showing the *BAD* practice. DO NOT FOLLOW it.
-
-```csharp
-    var histogram = meter.CreateHistogram<long>("MyHistogram");
-
-    // Configure a view to aggregate based only on the "location" tag.
-    .AddView(instrumentName: "MyHistogram", metricStreamConfiguration: new MetricStreamConfiguration
-        {
-            TagKeys = new string[] { "location" },
-        })
-
-    // Configure another view to aggregate based only on the "status" tag.
-    .AddView(instrumentName: "MyHistogram", metricStreamConfiguration: new MetricStreamConfiguration
-        {
-            TagKeys = new string[] { "status" },
-        })
-
-    // The measurement below will be aggregated into two metric streams, but both will have the same name.
-    // OpenTelemetry will issue a warning about this conflict and pass both streams to the exporter.
-    // However, this may cause issues depending on the backend.
-    histogram.Record(10, new("location", "seattle"), new("status", "OK"));
-```
-
-The modified version, avoiding name conflict is shown below:
-
-```csharp
-    var histogram = meter.CreateHistogram<long>("MyHistogram");
-
-    // Configure a view to aggregate based only on the "location" tag,
-    // and rename the metric.
-    .AddView(instrumentName: "MyHistogram", metricStreamConfiguration: new MetricStreamConfiguration
-        {
-            Name = "MyHistogramWithLocation",
-            TagKeys = new string[] { "location" },
-        })
-
-    // Configure a view to aggregate based only on the "status" tag,
-    // and rename the metric.
-    .AddView(instrumentName: "MyHistogram", metricStreamConfiguration: new MetricStreamConfiguration
-        {
-            Name = "MyHistogramWithStatus",
-            TagKeys = new string[] { "status" },
-        })
-
-    // The measurement below will be aggregated into two separate metrics, "MyHistogramWithLocation"
-    // and "MyHistogramWithStatus".
-    histogram.Record(10, new("location", "seattle"), new("status", "OK"));
