All,
I have a team of 5 developers, and we remote desktop into a development server which has entityspaces and mygeneration installed. When I tried to open the gridloader project, having found the pdf detailing this for the new admin templates, I was getting an error along the lines of "Unable to open this project, the project type is unsupported." When I searched (googled, its a verb now) for the error, I discovered a blog that talks about how WebApplicationProject is not a default install, and you have to install the WAP support seperately. Having just done this, I can now open the GridLoader solution...
Hope this helps someone.
