Hi, I hv downloaded the code sample but is not able to open them. When I try to open them I am having this error "The selected project was created by a newer version of this application and cannot be open". I am using Visual Studio 2010 Professional(with SP1) and hv also installed the trial version of Lightswitch 2011. Hope you guys can help. Thank you.

OK, found the problem... I was trying to open eg. Aquarium.sln instead of Aquarium.lsproj. Tks.
