Remarks

RequiresPreviewFeaturesAttribute marks an API as requiring preview functionality from the .NET runtime, its core libraries, and the compilers. This API is intended for platform-provided functionality and generally shouldn't be used in user code.

If you want to ship preview functionality in your own libraries, use ExperimentalAttribute instead.

For more information about marking APIs as preview, see Preview APIs.
