Polly Cache - InMemory

问题

I was looking for a good example which describes implementing Polly caching in .net core 2.1 using the memory cache option. I got to a point configuring the cache settings on startup.

   services.AddSingleton<Polly.Registry.IPolicyRegistry<string>, Polly.Registry.PolicyRegistry>((serviceProvider) =>
                {
                    PolicyRegistry registry = new PolicyRegistry();
                    registry.Add("myCachePolicy", Policy.CacheAsync<HttpResponseMessage>(serviceProvider.GetRequiredService<IAsyncCacheProvider>().AsyncFor<HttpResponseMessage>(), TimeSpan.FromMinutes(5)));
                    return registry;
                });
