Runtime error in DotNetNuke 4.9.1 with sample code applied

I am hoping to get a bit of help with your sample code. I've got a DotNetNuke 4.9.1 site up and going on my development server. I've downloaded your sample code and the authentication site working. I've gone through the Membership Sample Setup Guide.doc instructions in detail. The DotNetNuke Solution compiles but when I try to navigate to the home directory, I get the following error. Do you have any idea of what is going on here?? Any help would be greatly appreciated...

Re: Runtime error in DotNetNuke 4.9.1 with sample code applied

AfroMann,

Sorry for the very delayed response.

If you've not already found the solution to this problem. Please set a breakpoint on the CreateInstance(Type type, Boolean nonPublic) method located

in the Reflection.vb class.

If you inspect the type parameter I think you'll see that the type that is trying to be created does not match your namespace/assembly name for your

project.

Hope this helps.
