Where are Visual Studio breakpoints saved?
Solution 1:
They are saved in the <solutionname>.suo file. SUO stands for Solution User Options, and should not be added to source control.
No .vbproj.user files should be in source control either!
Solution 2:
Starting from Visual Studio 2015 CTP solution and project related files are stored in the .vs directory. The path to the suo file is .vs\<SolutionName>\v14\.suo for Visual Studio 2015.
