empty assembly

Oct 1, 2008 at 3:47 AM
I added feature with receiver to the project which has site definition couple of features .

and added some code to the feature receiver class.

I'm getting error when i activate this feature .Null reference exception.

Than i tried looking into the assembly created by wspbuilder which is in GAC.

I found empty assembly with out my class.

Is the any other settings i need to for feature with receiver?
