    We just purchase the radcontrol 2010 Q3. after install, the previous worked project got an error.

    Error 10 The "ValidateXaml" task failed unexpectedly.
    System.TypeLoadException: Could not load type 'System.ComponentModel.DefaultPropertyAttribute' from assembly 'System, Version=, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'.

    previous it worked under version 2010 Q1 trial version with visual studio 2008 V9.030729.1 SP .

    And I also checked at Reference Assemblies\Microsoft\Framework\Silverlight\v3.0\system.dll.
    it seems that dll file does not contain System.ComponentModel.DefaultPropertyAttribute. and the close one it contains is System.ComponentModel.DefaultValueAttribute

     Are you trying to compile Silverlight 4 assemblies (our official assemblies are only for Silverlight4) in Silverlight 3 project? 

    All the best,
