DataDog/dd-trace-dotnet v1.12.0

1.12.0

on GitHub

Note: NuGet packages are no longer required to enable automatic instrumentation in .NET Core or to enable the ASP.NET instrumentation in .NET Framework. If you are using NuGet packages Datadog.Trace.AspNet or Datadog.Trace.ClrProfiler.Managed, you may remove them from your application when you update the .NET Tracer. We will publish updated packages that are empty (no assemblies) for backwards compatibility, but these are now DEPRECATED.

NuGet package Datadog.Trace is still used for manual instrumentation or to configure the Tracer in code. Please keep the NuGet package version in sync with the installed Tracer if you will be mixing automatic and manual instrumentation in the same application.

Note: In these release notes and in the .NET Tracer documentation, "ASP.NET" refers to the legacy web framework included in .NET Framework, and "ASP.NET Core" refers to the modern open-source cross-platform web framework used in .NET Core.
