sry cant post all coding, but i already post important part.
using telerik, masterpage, mvc3
error 1)
the type or namespace name SysMaterial could not be found (are you missing a using directive or an assembly reference?)
error 2)
found conflicts between different version of the same dependent assembly <-- this one just solve already, i run telerik ->open access -> option -> IntelliTrace - >启用。 then restart VS2010 then run telerik ->open access ->upgrade reference
framework already is 4.0.
beside, i have search all article for adding reference, or change framework 4.0 client to framework 4.0 are not work for me.
needed your guy advice for help, thanks.

推荐答案
Not about coding problem, i just deleted Telerik OpenAccess Domain Context .tt file at FA.DAL and rebuild again already can run it.
