NullReferenceException

[EFLFE]

Hello. Visual studio shows an error when I open the project for the first time.

This window

It always shows that error when opening a file with this code:

#if INF
...
#endif
/*
...
*/

The last text from ActivityLog.xml:

I've tried to reproduce the issue with the piece of code you've provided, but I didn't encountered any errors. Could you share a file or a project where this happens?
