Corrupt project VS2012

Question

Opening a solution (2 projects) in VS2012, I get several errors:

1. Unable to load one or more breakpoints.
2. Value does not fall within the expected range (opening web.config)

Looks something is corrupted. Is there an easy way to recover? Where are the breakpoints stored? Which value is (suddenly) out of range? Thanks in advance for any help!

Answer 1

There is still a (hidden) .suo file. Removing that file resolves BOTH problems!

Answer 2

Find and delete .suo file from below correct place for Visual Studio 2015 project.

[Project Folder]\.vs\[Solution Name]\v14\.suo

I found the solution from here:
