When I try to open my .sln file, Visual Studio quits on me. I can open it by opening up TFS, getting a specific version, choosing the latest version, forcing an overrwrite, opening up the .sln file, and then ignoring an 'incompatible doc message".
However, I would like to know what's wrong and how it can be fixed, in case some day I can't do this.
How can this be fixed?
I would think this is more likely to be the .suo (which is a hidden file). These are know to corrupt (and this has been true since at least VC++ V6). Deleting it will clear all sorts of odd/erroneous behaviour in VS.
(The .suo holds local settings: which files are open and layout, breakpoints, bookmarks, ... only: nothing that really matters to the solution or projects.)
For Visual Studio 2015 and 2017: rather than being in the same location as the solution (.sln) file, it is now held in a, hidden, folder called .vs in the folder containing the solution file.
In Visual Studio 2022, the .suo is in \.vs\MySolution\v17\
