Can't find way to debug Internal Server Error (500) caused by new class - botframework

Question

I've read a lot of the postings about 500 errors because of the channel emulator, but this is not the case here. I took the standard bot template, which works just fine with the emulator, and replaced it with
ConnectorClient connector = new ConnectorClient(new
Uri(activity.ServiceUrl));
// calculate something for us to return
// int length = (activity.Text ?? string.Empty).Length;
string responseText=
***Bot_Application2.SilviaRestClass.GetRestResult(activity.Text);***
So the issue is in executing the GetRestResult method in the SilivaRestClass.
The code itself works, I'm using it in lots of other places, as it basically sets up a simple 1)get an input utterance in text, 2)send to my SILVIA AI server, and 3)get an utterance back routine. I have a feeling it has something to do with either private vs public methods, and/or [Serializable], based on what I have read so far. The code (minus the credentials) is below. Many thanks, in advance, for any suggestions to try.

I ended up resolving this by cut/paste the class inside the same namespace and physical .cs file. – Brian Garr just now edit
