DataDog/dd-trace-dotnet v2.0.1 on GitHub

This release supersedes 2.0.0-prerelease. Let us start by recalling the main changes of this version compared to the 1.31 one:

Highlights

.NET 6 support added
.NET Framework versions <4.6.1 are no longer supported
ASP.NET and ASP.NET Core resource names have been standardized to use controller/action and routes wherever possible
- ⚠️ This will change endpoints in the Datadog app
New integrations
- Couchbase
- Postgres v6
Public API changes
- Datadog.Trace.Tracer is now a singleton and its settings can be updated with Tracer.Configure
- Datadog.Trace.Tracer implements ITracer for use in DI
- Replace usages of Scope/Span classes with IScope/ISpan classes
Solves version conflict between automatic and manual instrumentation. Regarding this fix:
- on .Net Core, you need to upgrade custom instrumentation first. The fix will work with automatic instrumentation starting v1.28.8
- on .Net Framework, you need both the custom and automatic tracer to run on v2.x for the conflict to be solved. Futures upgrades won't show this issue anymore though.
Automatic logs injection now requires the application to be instrumented with automatic instrumentation. More details in our documentation
