When I try to open managedwifi example solution, I get the following error:
the project you are trying to open was not created using visual studio Tools for Applications. Visual Studio Tools cannot open projects that were created using other applications.

I have Visual Studio 2010 Express installed.
Any hint what may be wrong?
Thanks!
