Components

Datadog Agent: A service that runs on your application servers, accepting trace data from the Datadog Tracer and sending it to Datadog. The Agent is not part of this repo; it's the same Agent to which all Datadog tracers (e.g. Go, Python, Java, Ruby) send data.

Datadog .NET Tracer: This repository. A set of .NET libraries that let you trace any piece of your .NET code. Supports manual instrumentation and can automatically instrument supported libraries out-of-the-box.

Windows

  • Workloads
    • Desktop development with C++
    • .NET desktop development
    • .NET Core cross-platform development
    • Optional: ASP.NET and web development (to build samples)
  • Individual components

• .NET Core 2.1 SDK
• Optional: nuget.exe CLI v3.4.4 or newer
• Optional: WiX Toolset 3.11.1 or newer to build Windows installer (msi)
  • Requires .NET Framework 3.5 SP2 (install from Windows Features control panel: OptionalFeatures.exe)
  • WiX Toolset Visual Studio Extension to build installer from Visual Studio
• Optional: Docker for Windows to build Linux binaries and run integration tests on Linux containers. See section on Docker Compose.

Microsoft provides evaluation developer VMs with Windows 10 and Visual Studio pre-installed.

Building from a command line

From a Developer Command Prompt for VS 2017:

rem Restore NuGet packages
rem nuget.exe is required for command line restore because msbuild doesn't support packages.config
rem (see https://github.com/NuGet/Home/issues/7386)
nuget restore Datadog.Trace.sln

rem Build C# projects (Platform: always AnyCPU)
msbuild Datadog.Trace.proj /t:BuildCsharp /p:Configuration=Release;Platform=AnyCPU

rem Build NuGet packages
dotnet pack src\Datadog.Trace\Datadog.Trace.csproj
dotnet pack src\Datadog.Trace.OpenTracing\Datadog.Trace.OpenTracing.csproj
dotnet pack src\Datadog.Trace.ClrProfiler.Managed\Datadog.Trace.ClrProfiler.Managed.csproj

rem Build C++ projects (Platform: x64 or x86)
msbuild Datadog.Trace.proj /t:BuildCpp /p:Configuration=Release;Platform=x64

rem Build MSI installer (Platform: x64 or x86)
msbuild Datadog.Trace.proj /t:msi /p:Configuration=Release;Platform=x64

Linux

Minimum requirements

To build C# projects and NuGet packages only

• .NET Core SDK 2.1

To build everything and run integration tests

• Docker Compose

Building and running tests with Docker Compose

You can use Docker Compose with Linux containers to build Linux binaries and run the test suites. This works on both Linux and Windows hosts.

# build C# projects
docker-compose run build

# build C++ project
docker-compose run Profiler

# run integration tests
docker-compose run IntegrationTests
