How to retain the original stacktrace of an exception propagading between processes in .NET Core (.NET 6+)

[alexey-leonovich]

I want to propagate exceptions between .NET Core (.NET 6+) processes and retain the original stacktrace. Currently we use .NET Remoting for inter-process comunication.
We used Exception.PrepForRemoting in .NET FW 472, but this method doesn't exist in .NET Core anymore so exception stack is truncated.
ExceptionDispatchInfo.Throw(Exception source) is not a solution because ExceptionDispatchInfo can't be serialized.
What is recommended approach for today?
Thank you.

Remoting or binary serialization are deprecated and no longer a thing. You must design your own mechanism to format the stack trace.
There should be no way to retain the stack trace as-if it's thrown in the same process.

Thank you. That could be handy.
