I’ve setup a solution filter for an all c# solution to cut down on compile time. And it works great for that purpose. However, pretty much every time I get latest from git, it hits me with “Additional Projects Loaded/Unloaded in Solution Filter. Update Solution Filter” warning.

Nothing has changed. Out of curiosity I copied the .slnf file elsewhere and then compared the changes after I click Update Solution Filter link. Absolutely nothing changed. Still the same file.

Is this a bug, of am I using the solution filters wrong or am I missing something obvious, like a setting?
