When investigating failures, you may find StreamJsonRpc's tracing functionality useful.
With the JsonRpc.TraceSource property, you can listen for:
- Which server methods are registered
- Incoming and outgoing JSON-RPC messages and how they're being handled along the entire pipeline
- When listening is started
- RPC method invocation failures with full exception callstacks.
The above is just a sample. The full list of events is available on the JsonRpc.TraceEvents enum.
When connecting two processes using Windows (named) pipes, be sure to use PipeOptions.Asynchronous
when creating those pipes to be used with our JsonRpc class. All our I/O is asynchronous, and
without that flag, .NET Framework and .NET Core will hang.
