Using c# gRPC server I have IServerStreamWriter<ClientNotification> ClientNotificationStream to send user notifications

when I'm trying to call ClientNotificationStream.WriteAsync(parameters) I have

System.ObjectDisposedException: 'IFeatureCollection has been disposed.
Object name: 'Collection'.'```

IFeatureCollection has been disposed.
Object name: 'Collection'.. Internal Error:  StackTrace:    at Microsoft.AspNetCore.Http.Features.FeatureReferences`1.ThrowContextDisposed()

ClientNotificationStream was disposed when I need to do WriteAsync().To fix it I add

WaitHandle.WaitAny(new[] { context.CancellationToken.WaitHandle });

context is ServerCallContext
