I have been running into the problem that with the latest beta build If it detects I have VS opened on a different machine it warns me as before but now I cannot open any files from solution and if I try to look at project properties it gives me message box with an unspecified error. Is this a new 'feature'
It took longer than expected to get a working test network up and running, but I am seeing a clear problem here. Using VA 1549 I cannot open files from solution explorer when VA has disabled its self. However I am not seeing any error messages, I can open project and solution properties quite happily.
