Error - The debugger's worker process (msvsmon.exe) unexpectedly exited.

The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted.

I'm getting this error ever time I debug. I started after I set the Target Framework to .NET framework 4.7. It happens when the code hits a break point. No break point, no error, unfortunately I need break points when debugging of course.

Anyone experienced this? Thanks!

Fixed it by unchecking "Use Managed Compatibility Mode"

 Tools->Options->Debugging->General->"Use Managed Compatibility Mode"

Sorry I'm out of ideas. Maybe repost so others can help?

You've actually inspired me to do that. I was giving up on it already. Keeping fingers crossed. https://forums.autodesk.com/t5/revit-api-forum/quot-could-not-evaluate-expression-quot/m-p/8410505
