Code inspection: Redundant 'WithCancellation()' invocation

This inspection reports a .WithCancellation(...) call when the same cancellation token has already been applied earlier in the async-enumerable chain. The extra call is redundant and does not change how cancellation works.

Example

                var items = source
                    .WithCancellation(token)
                    .ConfigureAwait(true)
                    .WithCancellation(token);
            

                var items = source
                    .WithCancellation(token)
                    .ConfigureAwait(true);
            

Quick-fix

The quick-fix removes the redundant WithCancellation() call.
