Could not load file or assembly 'Microsoft.VisualStudio.xmlEditor'

Hi,

I am trying to customise WITs.

I exported Task.xml from my tfs, but when i try to open it in VS I get following error:

Cannot load "Filepath\Task.wit" Could not load file or assembly 'Microsoft.VisualStudio.xmlEditor, version = 11.0.0.0, culture=nuetral, publickeyToken=b03f5f7f11d50a3a' or one of its dependencies.  The system cannot fild the file specified.

I do have the .wit-file in the same folder as my .xml-file.

After same looking around, I found that this normally has to do with the version of tfs you're running, but I have VS Ultimate 2012 so this shouldn't be a problem. It's a tfs 2013 server that I'm connecting to, so I thought that might be a problem, but since your power tools need to match your VS I'm ok on that front as well.

Thanks for the help,

Ken
