Visual Studio 2015 with Update 2 - 'The Scc Di

问题:

Loading a project in Visual Studio 2015 with Update 2 (either automatically when VS start or manual load), I receive an error saying: 'The Scc Display Information package did not load correctly'.

The ActivityLog has:

I installed VS2015 with Update 2 over VS2015 with Update 1. I got the error (package ... did no load correctly).

I uninstalled VS2015 completely. I reinstalled VS2015 with Update 2 completely. I still have the same problem about 'The Scc Display Information' package did not load correctly'.

Update The problem seems similar to the same problem I had with VS2015 Update 1. But I think it is not related to NuGet because I have no package with "Scc" in it. I always associated "Scc" with Visual Source Safe (could it be related ?). I suspect the problem come from the registry but I can't figure out where.

I tried both solutions from this Stack Overflow link without success:

• run the command: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe" /resetskippkgs"
• Delete folder ComponenModelCache (C:\Users\XXXX\AppData\Local\Microsoft\VisualStudio\XX\ComponentModelCache)

Any idea how to fix this?

回答1:

This is caused if you have certain MSSCCI-based SCC providers installed. You can check your registry's HKLM key: SOFTWARE\WOW6432Node\SourceCodeControlProvider

If this key is present, that's likely causing the problem.

Proper Fix

Install the fix from KB3151378.

New installations of VS 2015 Update 2 after 4/11/2016 automatically include this fix and no manual installation of a fix is necessary.

Old workaround follows

If you don't use any of the SCC providers mentioned there, try renaming the key to SourceCodeControlProvider_ (added underscore). The package should then load cleanly.

We're working on shipping a fix for VS2015 Update 2 to resolve the issue even while you have MSSCCI-based SCC providers installed.

回答2:

I have just fixed this problem with VS2015 on Windows7Pro and I DIDN'T have the SOFTWARE\WOW6432Node\SourceCodeControlProvider registry key. I took Igor's advice and ONLY cleared the %HOMEPATH%\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache folder. When VS2015 restarted, the error was gone and VS 'rebuilt the cache'.
