@jeevanachandra Is the server reporting an error in its window? If could post a picture of the server errors or the logs from startup, that would be really helpful.

Also if you start the csharpserver plugin, does the error still persist?

useplugin csharpserver

Using the useplugin csharpserver & execute method reproduces the same error in the server window.
