I have upgraded from trial 2009 Q3 to trial 2010 Q1, and on any Silverlight 4 project (vs 2010 rc), if i just put the control and activate the isenabled property, the editor raise an exception. Same after compilation (successful but same error on browser).
Q1 not enterly silverlight 4 compatible ?
Error HRESULT E_FAIL has been returned from a call to a COM component.
