Ambiguous extension method

Question

I am making the following call to an extension method:

database.ExecuteScalar(command).NoNull(string.Empty);

I get an error t

Answer 1

Just in case somebody will need this...

Ambiguity can be resolved if concurrent namespaces which have extension methods with same name, are included at different levels (most inner included namespace will have priority).

For example:

using Namespace1;
namespace MyApplication 
{
    using Namespace2;
    ...
    db.Execute(); // Namespace2 Execute() will be called
}
