+## AndroidUseDesignerAssembly
+
+A bool property which controls if the build system will generate an
+`_Microsoft.Android.Resource.Designer.dll` as apposed to a `Resource.Designer.cs` file. The benefits of this are smaller applications and
+faster startup time.
+
+The default value is `true`.
+
+This setting is not backward compatible with Classic Xamarin.Android.
+So as a Nuget Author it is recommended that you ship three versions of
+the assembly if you want to maintain backward compatibility.
+One for MonoAndroid one for net6.0-android and
+one for net8.0-android. You can do this by using [Xamarin.Legacy.Sdk](https://www.nuget.org/packages/Xamarin.Legacy.Sdk).
+
+```
+<TargetFrameworks>monoandroid90;net6.0-android;net8.0-android</TargetFrameworks>
+```
+
+Alternatively turn this setting off until such time as both Classic and
+net7.0-android have been deprecated.
+
+.NET Projects which choose to turn this setting off will not be able to
+consume references which do use it.
+
+Added in .NET 8.  Unsupported in Classic Xamarin.Android.
