CodeLens references unhandled exception

[kiminuo]

Version Used: Version 16.10.0 Preview 1.0 (but I believe it is the same in 16.9 which was released yesterday).

Steps to Reproduce:

1. Clone pakrym/jab@3b5eaef
2. Open the project solution
3. Open jab\src\samples\ConsoleSample\Program.cs file
4. You should see an exception:

Expected Behavior:

No exception.

Actual Behavior:

Exception.

+1, also reproduceable on 16.9 with chyyran/Snowflake@baae6b, occurs when you open the file Snowflake.Framework.Tests.Configuration/ExampleConfigurationCollection.cs.

It seems generated source code is somewhat involved. ExampleConfigurationCollection invokes a source generator, but if you comment out AddSource, the problem magically disappears. I have ruled out any bugs in my diagnostic analyzers and the source generation code itself. The generated source code is well formed as well. It also happens regardless of EmitCompilerGeneratedFiles.

I have same problem, with Visual Studio 16.9.

Thanks for reporting and for the clear repro steps. Working on this in #51686.

Hmm. Looks like find usages is broken as well:

I wasn't able to reproduce this again, will give FAR failure a look separately.

I'm having this exact issue where a Source Generator is also involved. (Visual Studio version 16.9.4)
Have just disabled Code lens for now, but hoping it will be fixed soon.
