I compiled my code and got this error.
C:\Program Files (x86)\MSBuild\Microsoft\Xbox 360 ADK\Microsoft.Xbox360.Adk.targets(1372,5): error : Unsupported assembly reference(s): System.ComponentModel.DataAnnotations.dll;System.Windows.Controls.Data.Input.dll
After adding some text boxes, labels to the main page I am getting this error. Tried to do a rebuild-all, restart xbox etc, but none of them worked for me.
Edit: Even after removing the Page i am unable to get rid of this error.
