random cs files not opening in visual studio 2012

Question

So here\'s my pickle. I\'m using Visual Studion 2012 and been developing my application without a hitch. I opened VS today and I can open all the files as I normally would (cs

Answer 1

I have had this problem randomly with VS 2012, and though I haven't found the root cause (I feel it is a bug in Visual Studio because it doesn't happen in 2010 in the same projects), I found how to disable the annoying symptom and just proceed with debugging. There is an option to turn off the checksum file check, in Tools -> Options -> Debugging -> General:

Require source files to exactly match the original version Tells the debugger to verify that a source file matches the version of the source code used to build the executable you are debugging. If the version does not match, you’ll be prompted to find a matching source. If a matching source is not found, the source code will not be displayed during debugging.

The downside is, if you have breakpoints in a particular file that is affected by this issue, then you may find VS won't trace into that file, so this option should only be used (IMO) if there are files causing trouble that you don't care to debug.

I will update my answer as I find more.
