[severity:It's more difficult to complete my work]
Code Analysis, code colors and huge functionalities are broken because I get this error on VS :

Somehow they're either ending up witha null container in definite assignment, or a non-c# symbol (probably the former).

@CyrusNajmabadi How did you get this stack trace? It seems really wacky, as it shows SyntaxNode.get_Location() calling CSharpCompilation.CommonCreateErrorTypeSymbol(...), which I can't make sense of.

That frame is likely a glitch. But the rest looks good

[kirk56k]

I recently got into a very similar situation. I'm not sure if the stack trace is the same, but otherwise the errors listed are exactly the same. Unfortunately, I didn't really have time to debug it too much. I found it was caused by a particular line of code in my application. I changed said line in Notepad, after which I no longer received the error. Unfortunately, I can't share the contents of the code base in question, I asked, but my boss said no. I did convince them to allow me to share the full application dump of "ServiceHub.RoslynCodeAnalysisService.exe.25696.dmp", which probably contains the entirety of the code base it was analyzing in the first place, but I'm not going to tell them that. It's about 600mb, if you are interested, let me know and I'll post it somewhere. I understand if It's not enough to go on by itself. I've solved the problem for myself, but if I can help you guys find bugs, I'll do what I can.
