Problem in System.CmponentModel.Composition

Question

Hi I am using .net frame work 3.5.I have tried to include System.ComponentModel.Composition.dll from MEF_Preview_6 2009.7.8.0 (Final) 2009 Aug 28(http://labs.ashmind.com/reuse/library/system.componentmodel.composition). While including dll i am getting error as  You cannot add a reference to System.ComponentModel.Composition.dll as it was not build runtime.Silverlight Projects will only work with Silverlight assemblies

Hi Yes Gomathi. you cant add the .net version assemblies. You have tried to add .net version of assembly i guess. you can only add the silverlight version of System.ComponentModel.Composition.dll assembly. Silverlight projects allows you to add only assemblies which are created for Silverlight.
