7 years ago According to this LinqPad Driver Development document the place to look for the diagnostic logs is: %localappdata%\linqpad\logs\ which did indeed have the call stack data for the null-reference exception for this driver.

I haven't yet started debugging with a local copy of the code to find out exactly where the null-reference is being thrown from.
I am connecting to a SOAP 1.2 service endpoint hosted in Tomcat and winding up with a null reference exception in Linqpad when it attempts to generate the proxy to talk to the service.
Any chance you know where I can find the detailed exception stack trace so I can start digging?
