Microsoft.VisualStudio.Web.PasteJson.JsonPackage did not load properly

Question

I have visual studio express 2012 and it was working fine earlier I had run my solution once. But now when I do it, there appears a dialog box with the message!

the Microsoft.VisualStudio.Web.PasteJson.JsonPackage, Microsoft.VisualStudio.Web.PasteJson package did not load correctly.

the problem may have been caused by a configuration changhe or by installation of another extension. You can get more information by exmamining the file C:\Users\AppData\Roaming\Microsoft\VWDExpress\11.0\Log.xml

continue to show this error message?

How do I get rid of this error?

I started to see this on the fresh windows & VS 2013 Ultimate with Update 2 installation.

To resolve the problem, close all Visual Studio instances head over to

C:\Users\<your users name>\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache

and delete all the files in the folder.

It worked fine for me. Thanks to this article.

Just to confirm this works in VS2013, even though I didn't install any extension. – s.m. Dec 01 '14 at 17:47

Not relevant to VS 2012 express, but I experienced this problem with VS 2013 Premium. I had recently added the productivity power tools extension. To get back up and running, I loaded Visual Studio in safe mode:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE>devenv /safemode

And un-installed the productivity tools. The errors went away.

You need to clear the ComponentModelCache folder or rename it. For Visual Studio 2013, it’s located in the %LOCALAPPDATA%\Microsoft\VisualStudio\12.0 folder.

I had Visual Studio 2013 Professional and I got the same error. I couldn't remove it until I repaired VS installation. It took a while but now it works fine.

Partial installation of VS2013 Update 4 caused this issue for me. Repair fixed it. – Jonathan Nov 18 '14 at 08:19

Even a full installation can cause it if you have the older version of the Azure 2.5 SDK. https://connect.microsoft.com/VisualStudio/feedback/details/1029189/after-update-4-has-been-installed-such-packages-are-failed-to-load – Moby Disk Jan 15 '15 at 14:40

I had this problem as I had an older version of VS2012 Express (release on Web Platform installer dated 15/08/2012).

Try installing 'Visual Studio 2012 Express for Web (Latest)' with release date 22/10/2012 from the Microsoft Web Platform Installer.

That is all I did and I no longer get those messages.

This only worked because uninstalling VS2012 removed this folder C:\Users\\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache Consider just cleaning it. @user_v has the correct answer. :) http://limzhenghong.wordpress.com/2013/11/10/visual-studio-pastejson-jsonpackage-did-not-load-correctly/ – Itanex Nov 14 '14 at 08:08
