I can connect with Management console. I can connect with local programs. Last confirmation that there was a problem: • I created an SP that has a single return of the number 1. • It could have a return of nothing for the sake of testing. • After I created the SP, I ran schema compare on all of my instances and all but the Azure server showed the variance.
Update I have verified that this is explicitly with the server, in that now two different users on two different computers are having the same exact problem. TL;DR The query Visual Studio is executing is being blocked and the query times out. Turns out I've managed to work this out for our situation: timing out due to blocking! I ran a profiler trace with a filter on application name of Microsoft SQL Server Data Tools, Schema Compare to capture the Visual Studio schema compare events. It would reach a certain query and then stop, when VS would claim that the comparison was complete.
