End of life .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. Datadog recommends using the latest patch version of .NET Core 3.1, .NET 5, or .NET 6. Older versions of .NET Core may encounter the following runtime issues when enabling automatic instrumentation:

Runtime support policy for .NET Core APM

Datadog APM for .NET Core depends on the host operating system, .NET Core runtime, certain .NET Core libraries, and the Datadog Agent/API. These third party software systems support specific versions of .NET Core. When the external software no longer supports a version of .NET Core, Datadog APM for .NET Core also limits its support for that version.

Levels of support

LevelSupport provided
UnsupportedNo implementation. Contact customer support for special requests.
BetaInitial 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.
MaintenanceFull implementation of existing features. Does not receive new features. Support for bug & security fixes only.
End-of-life (EOL)No support.

Package versioning

Datadog APM for .NET Core practices semantic versioning. Version updates imply the following changes to runtime support:

  • Major version updates (for example 1.0.0 to 2.0.0) may change support for any runtime from Beta/GA to Maintenance/EOL.
  • Minor version updates (for example 1.0.0 to 1.1.0) won’t lower the level of support for one runtime but may add support for one.
  • Patch version updates (for example 1.0.0 to 1.0.1) will not change support for any runtime.
