## Supported .NET Versions
Packages shipped from this repository generally support all the officially
supported versions of [.NET
Core](https://dotnet.microsoft.com/download/dotnet-core), and [.NET
Framework](https://dotnet.microsoft.com/download/dotnet-framework) except for
versions lower than `.NET Framework 4.6.1`.
Any exceptions to this are noted in the individual `README.md` files.
## Getting Started
If you are new here, please read the getting started docs:
* [logs](./docs/logs/getting-started/README.md)
* [metrics](./docs/metrics/getting-started/README.md)
* [trace](./docs/trace/getting-started/README.md)
This repository includes multiple installable components, available on
[NuGet](https://www.nuget.org/profiles/OpenTelemetry). Each component has its
individual `README.md` file, which covers the instruction on how to install and
how to get started. To find all the available components, please take a look at
the `src` folder.
Here are the most commonly used components:
* [OpenTelemetry .NET API](./src/OpenTelemetry.Api/README.md)
* [OpenTelemetry .NET SDK](./src/OpenTelemetry/README.md)
Here are the [instrumentation
libraries](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/glossary.md#instrumentation-library):
* [ASP.NET](./src/OpenTelemetry.Instrumentation.AspNet/README.md)
* [ASP.NET Core](./src/OpenTelemetry.Instrumentation.AspNetCore/README.md)
* [Grpc.Net.Client](./src/OpenTelemetry.Instrumentation.GrpcNetClient/README.md)
* [HTTP clients](./src/OpenTelemetry.Instrumentation.Http/README.md)
* [Redis client](./src/OpenTelemetry.Instrumentation.StackExchangeRedis/README.md)
* [SQL client](./src/OpenTelemetry.Instrumentation.SqlClient/README.md)
Here are the [exporter
libraries](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/glossary.md#exporter-library):
* [Console](./src/OpenTelemetry.Exporter.Console/README.md)
* [In-memory](./src/OpenTelemetry.Exporter.InMemory/README.md)
* [Jaeger](./src/OpenTelemetry.Exporter.Jaeger/README.md)
* [OTLP](./src/OpenTelemetry.Exporter.OpenTelemetryProtocol/README.md)
(OpenTelemetry Protocol)
* [Zipkin](./src/OpenTelemetry.Exporter.Zipkin/README.md)
* [Prometheus](./src/OpenTelemetry.Exporter.Prometheus/README.md)
See the [OpenTelemetry registry](https://opentelemetry.io/registry/?s=net) for
more exporters.
## Customization
OpenTelemetry .NET is designed to be customizable and extensible. Here are the
most common customization and extension scenarios:
* [Building a custom instrumentation
library](./docs/trace/extending-the-sdk/README.md#instrumentation-library)
* [Building a custom log
exporter/processor/sampler](./docs/logs/extending-the-sdk/README.md)
* [Building a custom metrics
exporter/reader/exemplar](./docs/metrics/extending-the-sdk/README.md)
* [Building a custom trace
exporter/processor/sampler](./docs/trace/extending-the-sdk/README.md)
