I cannot create a new business project after installing silverlight 4 beta. It pops out a message saying " " Object reference not set to an instance of the object", I had silverlight 3 sdk installed before and I installed the "Silverlight 4 Beta Tools for Visual Studio 2010". I uninstalled both SL 3 and SL 4 from my machine and installed only the SL 4 bits.. but I still get the same problem. Anybody know how to get around this problem ?

I am not sure that is the problem, I have uninstalled all the related stuff for SL3 and SL4 and then installed the SL 4 beta. Now I cannot create the businees project, I have other project types installed.
update : I just checked, I created a new ria class library and then added a new business application to it and it works. It only happens if I logically seperate the project with in a folder under a solution. I have filed a bug in microsoft connect. Hopefully they will correct it.
I hope this will help some one.
