Runtime support policy for .NET Framework APM

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

Levels of support

Level	Support provided
Unsupported	No implementation. Contact customer support 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.
End-of-life (EOL)	No support.

Package versioning

Datadog APM for .NET Framework 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.
