Question

I’m currently developing a visual studio add-in, however when I close visual studio and shutdown my machine and come back the next day, I cannot build the add-in because it is currently loaded in visual studio. How do i fix this problem so I don’t have to manually remove delete and reinstall the add-in every time I wish to debug or change my add-in?

Answer 1

AddIns are usually loaded by .AddIn file which is placed in one of these locations

C:\Documents and Settings\All Users\Application Data\Microsoft\MSEnvShared\Addins\ C:\Documents and Settings\Computer.User\My Documents\Visual Studio 2008\Addins

So when I do AddIn development, I start Visual Studio with special .bat file. I also use the AddIn when working on other projects, so there are additional complications. Here is an example of the file I use:

:: My installed .AddIn file goes in All Users directory move 'C:\Documents and Settings\All Users\Application Data\Microsoft\MSEnvShared\Addins\Sample.AddIn' 'C:\Documents and Settings\All Users\Application Data\Microsoft\MSEnvShared\Addins\Sample.AddIn_'  :: just in case it got left from the previous session del 'C:\Documents and Settings\Computer.User\My Documents\Visual Studio 2008\Addins\Sample_dbg_.AddIn'  :: start Visual Studio and open AddIn solution 'C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe' D:\dev\Sample.sln /resetaddin Sample.Connect  :: this will execute after Visual Studio is closed del 'C:\Documents and Settings\Computer.User\My Documents\Visual Studio 2008\Addins\Sample_dbg_.AddIn'  :: This is needed because my installed AddIn, and the one I'm developing are in different directories, yet have the same name. That confuses studio and this line sets things straight 'C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe' /resetaddin Sample.Connect /Command File.Exit  :: restore installed AddIn file move 'C:\Documents and Settings\All Users\Application Data\Microsoft\MSEnvShared\Addins\Sample.AddIn_' 'C:\Documents and Settings\All Users\Application Data\Microsoft\MSEnvShared\Addins\Sample.AddIn'  exit 

I also do this on Prebuilt event in AddIn project:

copy '$(ProjectDir)\Sample_dbg_.AddIn' 'C:\Documents and Settings\Computer.User\My Documents\Visual Studio 2008\Addins\Sample_dbg_.AddIn' 

Also you could look into Visual Studio command line parameter /rootsuffix , but I wasn’t able to find a solution around that.
