Out of support .NET Core versions

The .NET Tracer works on .NET Core 2.0, 2.1, 2.2, and 3.0, but these versions reached their end of life and are no longer supported by Microsoft. See Microsoft’s support policy for more details. We recommend using the latest patch version of .NET Core 3.1 or .NET 5. Older versions of .NET Core may encounter the following runtime issues when enabling automatic instrumentation:

Issue Affected .NET Core Versions Solution More information
JIT Compiler bug on Linux/x64 2.0.x,
Upgrade .NET Core to the latest patch version, or follow steps in the linked issue DataDog/dd-trace-dotnet/issues/302
Resource lookup bug with a non en-US locale 2.0.0 Upgrade .NET Core to 2.0.3 or above dotnet/runtime/issues/23938
