VB -> C#: `GetType(Nullable(Of))` is not handled correctly

[jswolf19]

VB.Net input code

Public Class Test
    Public Function IsNullable(ByVal type As Type) As Boolean
        Return type.IsGenericType AndAlso type.GetGenericTypeDefinition() Is GetType(Nullable(Of))
    End Function
End Class

Erroneous output

public class Test {
    public bool IsNullable(Type @type) {
        return type.IsGenericType && ReferenceEquals(type.GetGenericTypeDefinition(), typeof(object));
    }
}

Expected output

public class Test {
    public bool IsNullable(Type @type) {
        return type.IsGenericType && ReferenceEquals(type.GetGenericTypeDefinition(), typeof(Nullable<>));
    }
}

Working on this, just about have it figured out. Well, my fix is working, but I don’t understand what’s happening with the test. The test is getting an unexpected using statement. Also, the fix is too narrow, doubt it works with multiple open generic parameters.

@jrmoreno1 Thanks for working on this!

I don't know how much help I can be, but if you point me to some code to look at, I'll be happy to try to help.
