Línea de trabajo
The payload names no source file. Start by reading the attached CSharplog.txt and the JsonRpc stack trace, which points to StreamJsonRpc reading from the debugger transport. Reproduce by running an Aspire app under the C# extension with a breakpoint set. Done means the IOException and the unbound breakpoint are explained, or a fix is shown to stop them.

Issue Description
When trying to run an Aspire app, errors are thrown in the debug console. This was fixed in a previous version of the C# extension.
JsonRpc Critical: 13 : Connection closing (StreamError: Reading JSON RPC from the stream failed with IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host..). System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host..
---> System.Net.Sockets.SocketException (10054): An existing connection was forcibly closed by the remote host.
--- End of inner exception stack trace ---

Also, I set a debug breakpoint - all that shows is a red outlined circle:
Steps to Reproduce
Load an Aspire app. Run it.
Expected Behavior
No Errors and can set debug breakpoints.
Actual Behavior
Errors and cannot debug.
