Since this type will be part of the produced .exe, we can use typeof(X).Assembly here:

Suggested change
public static void Main(string[] args) => BenchmarkSwitcher.FromAssembly(Assembly.GetEntryAssembly()).Run(args);
public static void Main(string[] args) => BenchmarkSwitcher.FromAssembly(typeof(__AutoGeneratedEntryPointClass).Assembly).Run(args);
