I can open a Solution or Project in VS2015 but when I try and open (in my case) a csharp code file (.cs) Visual Studio crashes (and not in a smart way).
This is also the case when creating a new code file, such as a class.
- Accessing the .log file yielded no errors.
- Deleting the Component Cache did not help
Here the entry from the Event Log:
