Question

• IDE: VS2010
• Framework.net: 4.0

I created a c# dll project under Visual Studio 2010, with several public classes, and I would like to use its classes inside another dll project, but written in vb.net.

In the vb.net dll project, I referenced the built c# dll, but impossible to import the c# classes. The namespace of the c# dll is even not recognized.

What must I do to see my c# classes?
If this is possible.

Example of class of my c# dll (namespace MyCSharpDll):

namespace MyCSharpNamespace {
  public class MyCSharpClass {
    public void Test() {}
  }
}

Example in a file of my vb.net dll:

Imports MyCSharpDll.MyCSharpNamespace

VS2010 indicates an error saying that MyCSharpDll is unknown or no public member.

Thank you.

Answer 1

I think you should rewrite your imports

Imports MyCSharpNamespace

without ‘MyCSharpDll’ part
