Register your own geo blocking middleware
public static IServiceCollection AddGeoBlocking(this IServiceCollection serviceCollection, GeoMethod useMethod)
//update configuration and set the type of call it makes.
serviceCollection.Configure<IFireWallConfig>(opt => opt.Geography.UseMethod = useMethod);
serviceCollection.AddSingleton(typeof(IGeoFactory), typeof(MyGeoRepository));
return serviceCollection;
