Full name

@azure-tools/typespec-azure-core/no-rest-library-interfaces

Resource interfaces from the TypeSpec.Rest.Resource library are incompatible with Azure.Core. Use the Azure.Core resource operation patterns instead.

❌ Incorrect

Extending from TypeSpec.Rest.Resource.ResourceOperations:

interface Widgets
  extends TypeSpec.Rest.Resource.ResourceOperations<Widget, Foundations.ErrorResponse> {}

✅ Correct

Define a custom interface using Azure.Core operations:

interface MyResourceOperations<TResource extends TypeSpec.Reflection.Model> {
  read is ResourceRead<TResource>;
}

interface Widgets extends MyResourceOperations<Widget> {}
