BTW, this app works fine with Android and Windows.

Hi @SantosVictorero. We have added the "s/needs-repro" label to this issue, which indicates that we require steps and sample code to reproduce the issue before we can take further action. Please try to create a minimal sample project/solution or code samples which reproduce the issue, ideally as a GitHub repo that we can clone. See more details about creating repros here: https://github.com/dotnet/maui/blob/main/.github/repro.md

This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

I've just hit this wall with something similar in VS 2022 and VS 2022 preview on macos Monteray. Used the simulator iPhone 14 Pro iOS 16.0 and Andoid Emulator.

I have not been able to pair to my Mac either since I updated to Ventura: See https://github.com/dotnet/maui/issues/10979

Also as you can see from my post this is a Grpc issue of .NET Maui and iOS.

I have been using Grpcweb with Blazor WebAssembly without any problems for a while.

Also as I said before, this app works fine with Android and Windows. Although I have not been able to use Windows with authentication do to another issue: https://learn.microsoft.com/en-us/dotnet/maui/platform-integration/communication/authentication?tabs=windows

Hopefully all those issues are addressed ASAP.

Finally I was able to pair to my Mac and I created a repro of this bug at: https://github.com/SantosVictorero/Maui-Practice/tree/master

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

Is there any known workaround for this? I understand the implementation of the GRPC library causes this, but it is very problematic not to have any known way to support GRPC in MAUI on macos.

[AramMar]

the same issue in my side, Is there any known workaround for this?

[AramMar]

hi @SantosVictorero, did you find any workaround for this issue?

[samhouts]

@rolfbjarne Any advice here?

[rolfbjarne]

Grpc is deprecated: https://grpc.io/blog/grpc-csharp-future/

Use Grpc.Net.Client instead: https://github.com/grpc/grpc-dotnet

See also https://learn.microsoft.com/en-us/aspnet/core/grpc/?view=aspnetcore-7.0

hi @SantosVictorero, did you find any workaround for this issue?

Sorry @AramMar, I just saw your post. I never found a workaround, I had to postpone that project.

[SantosVictorero]

Grpc is deprecated: https://grpc.io/blog/grpc-csharp-future/

Use Grpc.Net.Client instead: https://github.com/grpc/grpc-dotnet

See also https://learn.microsoft.com/en-us/aspnet/core/grpc/?view=aspnetcore-7.0 @rolfbjarne, thanks for the late reply! :-)

[AramMar]

thanks for your reply, i am using Grpc.Net.Client, unfortunately the same issue for that one also

[rolfbjarne]

thanks for your reply, i am using Grpc.Net.Client, unfortunately the same issue for that one also

In that case, please file a new issue and provide a test project we can use to reproduce the problem.
