End of life .NET runtime versions
The .NET Tracer works on .NET Core 2.0, 2.1, 2.2, 3.0, and 3.1, and on .NET 5 and 7, 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 6 or .NET 8. Older versions of .NET and .NET Core may encounter the following runtime issues when enabling automatic instrumentation:
Supported Datadog Agent versions
| Datadog Agent version | Package version |
|---|
| 7.x | Latest |
| 6.x | Latest |
| 5.x | Latest |
.NET runtime support policy
The .NET Tracer depends on the host operating system, .NET runtime, certain .NET libraries, and the Datadog Agent/API. These third party software systems support specific versions of .NET and .NET Core. When the external software no longer supports a version of .NET, the .NET Tracer also limits its support for that version.
Levels of support
| Level | Support provided |
|---|
| Unsupported | No implementation. Contact customer support for special requests. |
| Preview | 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
The .NET Tracer 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 Preview/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.
