<p>I am on VS 2015 Update 2 Enterprise version
I have restarted VS several times, killed the process when i got that message and sometimes i stopped the app when i got that message.
I have also unloaded the projects that are not necessary for my task at this moment but still same problem</p>

<p>Microsoft Visual Studio is waiting for an internal operation to complete. If you regularly encounter this delay during normal usage, please report this problem to Microsoft.
