Compare with Unmodified VS2017 stopped running

[sebascomeau]

• GitHub Extension for Visual Studio version: 2.4.0.1202
• Visual Studio version: 15.5.5

I updated to the latest version and each time I try to do "Compare with Unmodified..." on a file that has changed then VS2017 hang and stop running.

I did a revert to version 2.2.0.10 and everything is fine now.

@sebascomeau Could you try installing the previous version, v2.3.6.391, and see if it works for you?
You can download the vsix from https://ghfvs-installer.github.com/releases/2.3.6.391/GitHub.VisualStudio.vsix and double click it to install it.

Hi @sebascomeau,

Thanks for letting us know - that is strange as the "Compare with Unmodified..." feature is a part of Visual Studio Team Explorer and not our extension...

I've just tried it locally and didn't see a problem, so it looks like it's something to do with your local setup. If you get a chance to go back to a version that is crashing, I wonder if you'd be able to attach a debugger and get a stack trace of where the crash is occurring?

You can do this by running another instance of Visual Studio and choosing "Debug -> Attach to Process" then selecting devenv.exe from the list.

Another thing you could try is clearing the MEF cache. There are instuctions for that here.

I'm experiencing the same.

Hi @TylerBrinkley. This looks like it's becoming a common issue. Could you try clearing the MEF cache as described here?

[TylerBrinkley]

I already reverted.

[sebascomeau]

I removed it from VS2017 then reinstall it.
No more bug now.

Good to know @sebascomeau, thanks for getting back to us! I suspect that clearing the MEF cache would have the same effect, but whatever was easiest for you!

@TylerBrinkley,

Could you try installing the following version over your reverted install (download the .zip and open the .vsix file from inside it):
https://ci.appveyor.com/project/github-windows/visualstudio/build/2.4.1.1219/artifacts

It includes a workaround for this issue. Please let us know if this version works as expected!

[TylerBrinkley]

@jcansdale It's working for me

[jcansdale]

@TylerBrinkley thanks for the quick reply! Good to know this version is working. 👍

Confirming that clearing the MEF cache fixed the issue for me.

@jcansdale
I experienced the problem described and version 2.4.1.1219 resolved this.
