I have developed a Outlook Addin using VSTO in Visual Studio 2010, on Windows

I have developed a Outlook Addin using VSTO in Visual Studio 2010, on Windows XP/SP 3.

  1. Build the VSTO solution, and I open Outlook 2010.
  2. I see that the Add in has been installed. ( which is strange ).
  3. Shut down Outlook.
  4. Clean the VSTO solution 5) Open Outlook 2010, the add in is not
    there.

So I believe Outlook understands that an Outlook add in is there, but I dont want the mentioned behaviour.

What am I looking for :-

I have created the installer using ClickOnce .

I should only see the Outlook addin , once I have executed the installer.

Any ideas shall be helpful.

    When you build a VSTO addin, it gets automatically installed on your development machine. It is Visual Studio that is doing this for you, to make debugging easyer.

    You can probably uninstall your addin automatically by using post-build events, but “Clean project” may be just as easy.
