Runtime support policy for .NET APM

Datadog APM for .NET is built upon dependencies defined in specific versions of the host operating system, .NET runtime, certain .NET libraries, and the Datadog Agent/API. When these versions are no longer supported by their maintainers, Datadog APM for .NET limits its support for these as well.

Levels of support

Level Support provided
Unsupported No implementation. Contact our customer support team for special requests.
Beta Initial implementation. May not yet contain all features. Support for new features, bug & security fixes provided on a best-effort basis.
General Availability (GA) Full implementation of all features. Full support for new features, bug & security fixes.
Maintenance Full implementation of existing features. Does not receive new features. Support for bug & security fixes only.
Legacy Legacy implementation. May have limited function, but no maintenance provided. Contact our customer support team for special requests.
End-of-life (EOL) No support.

Package versioning

Datadog APM for .NET practices semantic versioning.

As this relates to downgrading runtime support, it implies:

  • Major version updates (e.g. 1.0.0 to 2.0.0) may change support for any runtime from Beta/GA to Maintenance/Legacy/EOL.
  • Minor version updates (e.g. 1.0.0 to 1.1.0) will not change support for any runtime.
  • Patch version updates (e.g. 1.0.0 to 1.0.1) will not change support for any runtime.
