I've started a new project on AppStudio, since I'm a real beginner on Windows and I wanted I fast way to get a feeling of how a basic universal app project works.
I have downloaded the source code from the AppStudio web Platform and started it in VSE 2013, but as soon as I try to run it on my machine (or on the simulator), I get this error (I'm translating it):
Exception of first-chance of type 'Windows.UI.Xaml.Markup.XamlParseException' in AppStudio.exe
Information WinRT: E_UNKNOWN_ERROR [Line: 38 Position: 21]
Exception first-chance of type 'System.Exception' in AppStudio.exe
Program '[3004] AppStudio.exe' has been terminated with code -1 (0xffffffff).
Thank's!
