Hello, I have the problem that if I want to cancel the ResponseStream with a CancellationTokenSource.Token, an exception occurs.

What version of gRPC and what language are you using?

2.45.0

What operating system (Linux, Windows,...) and version?

Android & Windows

What runtime / compiler are you using (e.g. .NET Core SDK version dotnet --info)

OS Name: Windows
OS Version: 10.0.22000
OS Platform: Windows
RID: win10-x64
Base Path: C:\Program Files\dotnet\sdk\6.0.300-preview.22204.3\

Host (useful for support):
Version: 6.0.4
Commit: be98e88c76

.NET SDKs installed:
6.0.202 [C:\Program Files\dotnet\sdk]
6.0.300-preview.22204.3 [C:\Program Files\dotnet\sdk]

What did you do?

I have an ASP core server that has full code

public override Task GetReadStream(WriteData request, IServerStreamWriter<StateResponse> responseStream, ServerCallContext context)
        {
                while (!context.CancellationToken.IsCancellationRequested)
                {
                    await Task.Delay(1000);
                }

                StopReadMessageFromClient();

            return ResponseStreamTask;
        }

Then I have a NET MAUI application that has complete code

DataReadStream = dataClient.GetReadStream(new WriteData(), headers);
await foreach (StateResponse data in DataReadStream.ResponseStream.ReadAllAsync(StreamCancellationTokenSource.Token))
                        {
                            //TODO
                        }

If I now want to cancel the stream on the client (NET MAUI) side, I do the following

StreamCancellationTokenSource?.Cancel();

So and here comes the difference I use the Grpc.Net.Client.Web because unfortunately Android only supports that then there is an error.
If I use the Grpc.Net.Client with Windows Application it works as desired

What did you expect to see?

It would be nice if both worked the same way

What did you see instead?

Make sure you include information that can help us debug (full error message, exception listing, stack trace, logs).

IMPORTANT: An exception only occurs if the server has already sent data and you then cancel

Android testing with gRPC isn't well tested yet, we are working on improving this for .NET 7.

You can use standard unary calls instead of streaming for now to workaround this.

We're using dotnet/runtime#69095 to track better support on mobile platforms. Thanks for the bug report.

Btw, this issue isn't in grpc-dotnet. I've also created an issue in dotnet/runtime to fix it in .NET Android's HttpClient - dotnet/runtime#69464
