Xamarin.Android - typeof and GetType always return System.RuntimeType

I am developing a Xamarin.Android WebView application, and in an attempt to use Reflection to implement some AJAX methods, I have noticed that both Object.GetType and typeof always return System.RuntimeType.

This happens regardless of what I pass to them - it happens when I pass string, int, MyClass, etc to typeof, as well as when I call GetType on instances of these classes.

Minimum runnable code is trivial:

private class HybridWebViewClient : WebViewClient
{
    public static type Test() {
        Log.Debug("TypeDebug", typeof(string));
        Log.Debug("TypeDebug", typeof(bool));
        Log.Debug("TypeDebug", typeof(MyClass));
        Log.Debug("TypeDebug", "test".GetType());
        Log.Debug("TypeDebug", (34).GetType());
        Log.Debug("TypeDebug", (new MyClass()).GetType());
    }
}

All of the above print "System.RuntimeType". The equivalent code compiled using .NET prints the expected values - System.String, System.Bool, etc.

Has anyone else using Xamarin.Android encountered this? If so, is there a workaround? It is making the use of Reflection impossible for me, and I need it to pass information between JavaScript running in the WebView and the app itself
