Having real trouble getting this installed. Have installed SP1 which broken Windows 7 Phone Developer tools. Uninstalled everything and now am missing the entity framework project templates ARRHH. Can you please post the solution / code from the demo I would like to see if my project is loading properly... Thanks
@Jamie XX:Sorry for the trouble... if I understand you correctly, installing Visual Studio SP1 as part of the Juneau CTP3 broke the Win7 Phone dev tools? Also, it sounds like uninstalling VS SP1 or Juneau broke your EF templates. This video page is not a great place to troubleshoot, but you should post that to the Juneau/SSDT forums: (http://social.msdn.microsoft.com/Forums/en-US/ssdt/threads/).
Also you didn't mention this, but I did want to note that Juneau CTP3 does not include the EF/App integration in this video as I mentioned in a previous comment.
Is this functionality now available?
