Hello, I've been running into a rather frustrating issue with Visual Studio 2012 (and 2010 actually). We have developers that jumped the gun and started using 2012 with our product even though we were previously working in 2010, with that changes were made to our project and solution (I can't detail them I wasn't involved) that seemed to make it work in both 2010 and 2012.
I first noticed this developing in 2010, after merging from trunk in Team system I was no longer able to debug. The browser would simply stop loading the page, inspecting the session with Fiddler yielded the following details below. I switched to 2012 to see if this would help the situation, and for a while it did. On my last merge which seems to have involved a quite auto-merge of the project file all of the sudden I'm having the same error. What could cause the debugger to suddenly abort while loading the page? I feel like I have my hands tied, any help would be appreciated.
