Visual Studio "Orcas" add-ins don’t appear in the Add-In Manager (March 2007 CTP)

If you have tried to create an add-in with the wizard in the March 2007 CTP of Visual Studio “Orcas”, you will have noticed that when you try to debug the add-in, it is not loaded. In fact, it does not appear in the Add-In Manager of the second instance of Visual Studio. This is because this CTP still places the .AddIn linkedĀ file (the one with the little arrow in the Solution Explorer) in the folder “C:\Documents and Settings\<user>\My Documents\Visual Studio 2005\AddIns”. To solve it:

  • Create the folder “AddIns” inside the folder “C:\Documents and Settings\<user>\My Documents\Visual Studio Codename Orcas\” (by default it is not created)
  • Move the .AddIn file to that folder
  • Remove the linked file from the Solution Explorer and add it pointing to the new location.
