use vb.net class library in c# Project

Question

I'm trying to use a vb class in my C# project. I create a new vb project (with this vb class), compiled it and added a reference from the c# project to the vb project. When I'm trying to get into to vb class from C# class I can't find it. When I'm trying to "using" the Namespace I get Error. I can't reach this class no meter what!! any suggestions?

Show some code how you access the class and the code of the class. What is the excact error? — Fox32

Is the class public? If not, you won't be able to see it from your C# project.

Check you've got the namespace right, noting that VB projects have a default namespace which is automatically prepended to whatever's in the source, IIRC. When in doubt, use something like Reflector or ILDASM to see what's in the assembly.

I agree - in my experience this is usually the project default namespace.

As you didn't post any code, I can only guess - is the class in the vb project marked as public?
