Question

Is there a way to create a System.Windows.Forms.BindingSource from an internal class? Or would I have to make the class public?

When the class is internal, it does not appear in the Add New Data Source wizard in Visual Studio.

Answer 1

By definition, internal classes aren’t visible outside of their assembly. This includes the assemblies used to drive the Add New Data Source wizard.

You can do what you describe if you write the code for it – and if you return the internal class as a reference with a public interface type.

public voide BindingSource GetMyBindingSource()
{
    return new MyInternalBindingSource();
}
