Unable to load extension in VS2015 #2334

Open StanleyGoldman opened 5 years ago

StanleyGoldman commented 5 years ago

So far this only happens on my machine. We are unable to reproduce this on @jcansdale's machine.

I'm unable to load the extension in Visual Studio 2015 after installation. If I delete the files GitHub.TeamFoundation.15.dll and GitHub.TeamFoundation.16.dll the extension loads as exptected.

We determined the cause to be a result of the interactions between "Customize Visual Studio Window Title" and our extension in Visual Studio 2015. "Customize Visual Studio Window Title" attaches a global assembly redirect handler that enabled the use of VS2017+ assemblies in VS2015, causing the crash you see above.
