Call a c# parameterized Function from vb.net

I have a vb.net app that I want to use to make a call to a c# function that has a collection of class objects as a parameter. I have tried constructing a class with the same structure in the vb.net app and declaring a list of objects populating them with data and passing these into the c# class but I get a conversation error

List(of AddressClass) cannot be converted to List(Of AddressClass)

Is it possible to achieve this? If so, then how?

The function is:

public static string callMain(List<AddressClass[]> Addresses)
{
    // code.......
}

You don't need to duplicate any classes. The whole beauty of the .NET Framework is the interchangeability of the languages. Just use the AddressClass definition which is used by the C# function. If the C# project is references in the VB one then your VB Code will recognise it.

So e.g. if the C# project's namespace is My.CSharp.Project then in VB you can just Dim list As new List(Of My.CSharp.Project.AddressClass).

Basically just treat the C# classes just like any other library. You don't know or care what language the System.IO classes are written in, do you? You just use them. The same goes for your C# project. In fact if you'd compiled your C# project to a DLL and manually imported it into your VB.NET project, you wouldn't even necessarily know it was a C# project - all you've got at that time is a compiled binary file.
