Answer 1

After long time debuging, have found the solution:

public static class ObjectTypeHelper
{
    public static T Cast(this Java.Lang.Object obj) where T : class
    {
        var propertyInfo = obj.GetType().GetProperty("Instance");
        return propertyInfo == null ? null : propertyInfo.GetValue(obj, null) as T;
    }
}

Usage example:

 var message = list.GetItemAtPosition(e.Position).Cast();
 bundle.PutInt("Message", message.ID);

After careful sdk study have found MonoDroid integrated extension for this purpose:

public static TResult JavaCast(this Android.Runtime.IJavaObject instance)
where TResult : class, Android.Runtime.IJavaObject
