• Visual Studio Team System VS crashes when using unit tests

  Hello,   When I'm running unittest in visual studio  I often get the following error msgbox: COM object that has been separated from its underlying RCW cannot be used.

It is recommended that you restart the application as soon as possible Error: HRESULT: 0x80131527 File: vsee\internal\inc\vscomptr.inl Line number: 473 After closing these 3 msgboxes the app shuts down.

• Visual Studio Team System Red x on documents folder in team explorer

  Hi all, I have TFS beta 3 refresh and every thing is working fine at the client side besides the fact that on some of the machines I cant access the documents folder from the team explorer.

It is also possible to access the documents from the share point portal (right clicking on the team project name) and access the "documents and lists" section. I have also tried to copy the http-url ( http://[servername]/sites/[Project ]) to an IE on a client and there the sharepoint sit ...Show All
