Errors in Rhino Mock

Hi,

while building the project, I am getting Rhino mock errors in that one of them is 'Rhino.Mocks.MockRepository' does not contain a definition for 'StrictMock' and no extension method 'StrictMock' accepting a first argument of type 'Rhino.Mocks.MockRepository' could be found (are you missing a using directive or an assembly reference?)

Please help me out to resolve this.

Thanks and regards
Vandana
