 # .NET for Android warning XA1024
 
-## Example messages
+This warning has been removed in .NET 11.
 
-```
-warning XA1024: Ignoring configuration file 'Foo.dll.config'. .NET configuration files are not supported in .NET for Android projects that target .NET 6 or higher.
-```
-
-## Issue
-
-No support for [configuration files][config] such as `Foo.dll.config`
-or `Foo.exe.config` is available in .NET for Android projects.
-[`<dllmap>`][dllmap] configuration elements are not
-supported in .NET 6 at all, and other element types for compatibility
-packages like [System.Configuration.ConfigurationManager][nuget] have
-never been supported in .NET for Android projects.
-
-[config]: /dotnet/framework/configure-apps/
-[nuget]: https://www.nuget.org/packages/System.Configuration.ConfigurationManager/
-
-## Solution
-
-Use a supported alternative for [`<dllmap>`][dllmap], such as the
-[NativeLibrary][native] API.
-
-Use an alternative for application settings such as
-[Preferences][preferences] in Xamarin.Essentials.
-

+The warning was previously issued for `.config` files included in the
+build output, but it produced false positives for unrelated files such
+as `nuget.config`. Since `.config` files are already excluded from the
+publish output and the .NET 6 transition period is long past, the
+warning is no longer necessary.
