Unhandled ChannelClosedException while debugging #53325

Closed davidkarlsson closed 8 months ago

davidkarlsson commented 8 months ago

Is there an existing issue for this?

Describe the bug

While pausing the debugger in another project than the one that is running ASP.NET Core the process running the web server will consistently crash with an unhandled ChannelClosedException if I pause long enough at a breakpoint.

The project I'm pausing the debugger with is running a gRPC server which the process that is running ASP.NET is connected to with bi-directional streaming calls but I'm not sure if that's related to this issue in some way.

Expected Behavior

I don't expect the process running ASP.NET Core to crash just because I'm pausing the debugger at a breakpoint.

Steps To Reproduce

I have not been able to reproduce this in a minimalistic project and I unfortunately can't share the projects where this happens.
