ambiguous class with namespace names in 2 dlls

Question

I\'ve imported 2 dlls to my application (third party) Now both of them have a namespace with same name. For example A.B and in both of them there is a class again with a same na

Answer 1

Just a little improvment or enhanced information: If you have multiple usings, the "extern alias lib1;"-line must be the very first of those usings (But also MS VS informs you about that).

Answer 2

Let's suppose that you have 2 assemblies (ClassLibrary1.dll and ClassLibrary2.dll) that both define the same class in the same namespace:

namespace Foo
{
    public class Bar
    {
    }
}

Now in the consuming project you could define an additional alias in the references of the class library:

And now you could do the following to help the compiler disambiguate:

extern alias lib1;
extern alias lib2;

class Program
{
    static void Main()
    {
        var barFromLib1 = new lib1::Foo.Bar();
        var barFromLib2 = new lib2::Foo.Bar();
    }
}
