Recently a few of my desktop applications stopped working, so I opened them up in VS 2012 Express Desktop, and tried debugging them.
It seems when the code tries to connect to the database I get the following error.
Could not load file or assembly 'System.Transactions.dll' or one of its dependencies. is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
I am not sure what has changed or how to fix it - any help would be great.
