Async-iterator 'StreamLoggingBehavior<TRequest, TResponse>.Handle(TRequest, CancellationToken, StreamHandlerDelegate<TRequest, TResponse>)' has one or more parameters of type 'CancellationToken' but none of them is decorated with the 'EnumeratorCancellation' attribute, so the cancellation token parameter from the generated 'IAsyncEnumerable<>.GetAsyncEnumerator' will be unconsumed

Async-iterator 'StreamRequestValidationBehavior<TRequest, TResponse>.Handle(TRequest, CancellationToken, StreamHandlerDelegate<TRequest, TResponse>)' has one or more parameters of type 'CancellationToken' but none of them is decorated with the 'EnumeratorCancellation' attribute, so the cancellation token parameter from the generated 'IAsyncEnumerable<>.GetAsyncEnumerator' will be unconsumed

Async-iterator 'StreamCachingBehavior<TRequest, TResponse>.Handle(TRequest, CancellationToken, StreamHandlerDelegate<TRequest, TResponse>)' has one or more parameters of type 'CancellationToken' but none of them is decorated with the 'EnumeratorCancellation' attribute, so the cancellation token parameter from the generated 'IAsyncEnumerable<>.GetAsyncEnumerator' will be unconsumed

Possible null reference assignment.

Async-iterator 'StreamInvalidateCachingBehavior<TRequest, TResponse>.Handle(TRequest, CancellationToken, StreamHandlerDelegate<TRequest, TResponse>)' has one or more parameters of type 'CancellationToken' but none of them is decorated with the 'EnumeratorCancellation' attribute, so the cancellation token parameter from the generated 'IAsyncEnumerable<>.GetAsyncEnumerator' will be unconsumed

Nullability of reference types in return type of 'Task<TResult?> DiagnosticsProvider.ExecuteActivityAsync<TResult>(CreateActivityInfo createActivityInfo, Func<Activity?, CancellationToken, Task<TResult>> action, CancellationToken cancellationToken = default(CancellationToken))' doesn't match implicitly implemented member 'Task<TResult> IDiagnosticsProvider.ExecuteActivityAsync<TResult>(CreateActivityInfo createActivityInfo, Func<Activity?, CancellationToken, Task<TResult>> action, CancellationToken cancellationToken = default(CancellationToken))'.

Possible null reference assignment.

Possible null reference assignment.

Nullability of reference types in type of parameter 'serializer' of 'bool MessagePackHybridCacheSerializerFactory.TryCreateSerializer<T>(out IHybridCacheSerializer<T>? serializer)' doesn't match implicitly implemented member 'bool IHybridCacheSerializerFactory.TryCreateSerializer<T>(out IHybridCacheSerializer<T>? serializer)' (possibly because of nullability attributes).

Possible null reference return.
