.NET for Android error XA4248

Example message

error XA4248: Could not find NuGet package 'Xamarin.Kotlin.StdLib' version '1.9.0' in lock file. Ensure NuGet Restore has run since this <PackageReference> was added.

Issue

The NuGet lock file has not been generated and thus Java dependencies from NuGet packages cannot be resolved.

Solution

Run NuGet Restore for the project to ensure the lock file has been generated.
