VS Extensions for SharePoint in 64 bit?

Sorry to say but it is not supported. You will have to use a 32 bit environment for development and use the output files on a 64 bit deployment. The reason is that even though VS can be installed in a 64 bit environment, it is still a 32 bit application and SharePoint is a 64 bit application.

    What a significant shame…has this been fixed?

  2. Obviuously this is not an issue the product teams like, so assuming they are working to fix it, is a safe bet. I have not heard of any scheduled releases in this area, but if there are I sure would like to know. 🙂
