Xamarin Oreo Adaptive Icons

Question

Did any of you successfully make use of the "Adaptive Icons" for xamarin android, introduced in Oreo?

I managed to make it work, if the .png images are placed in the Drawable-folders, but not if they are placed in the MipMap-folders.

I have followed the guidelines in this link, and it works when using Android Studio... weird I think?

Thanks to this blog post I was able to use adaptive Icons in my Xamarin.Forms Android app.

Steps involved

1. Create an adaptive Icon using Android Studios Image Asset Studio (note that it takes a while before you can actually add a new Image Asset in Android Studio as the editor is first initializing.)
2. Once the Launcher Item is created you can open the res directory in file explorer.
3. Copy all mipmap-*-folder into the Xamarin.Forms Android Project Resources directory.
4. Update the AndroidManifest.xml to contain the new icon and roundIcon asset

<application android:label="MyApp"
               android:icon="@mipmap/ic_launcher"
               android:roundIcon="@mipmap/ic_launcher_round"
               android:appCategory="productivity"></application>

5. In the MainActivity also update the Icon and RoundIcon values

namespace MyApp.Droid
{
    [Activity(Label = "MyApp", Icon = "@mipmap/ic_launcher", RoundIcon = "@mipmap/ic_launcher_round", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
    public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
    {
