I have several styles (from the styles.xml file) that include properties such as android:inputType for EditText & android:orientation for LinearLayout. Although this does not (at least not for anything I have noticed yet, but I am relatively new to Xamarin.Android) cause a problem when debugging, they give the squiggly red or green error or warning such as "Missing explicit orientation" or "No input type specified". Is this to be expected? It is also strange, for example, that even though the designer applies the android:orientation for LinearLayout, it still claims that I did not specify it. It would be nice if the designer recognized when I specify properties in my styles.
