This repo contains the MemoryCache plugin for the Polly Cache policy. It targets .NET 4.0, .NET 4.5 and .NET Standard 1.3.

What is Polly?

Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, Cache aside and Fallback in a fluent and thread-safe manner. Polly targets .NET 4.0, .NET 4.5 and .NET Standard 1.1.

Polly is a member of the .NET Foundation!

Installing Polly.Caching.MemoryCache via NuGet

Install-Package Polly.Caching.MemoryCache

You can install the Strongly Named version via:

Install-Package Polly.Caching.MemoryCache-Signed

Supported targets

Polly.Caching.MemoryCache works with Polly v5.4.0 and above.

How to use the Polly.Caching.MemoryCache plugin

// (1a): Create a MemoryCacheProvider instance in the .NET Framework, using the Polly.Caching.MemoryCache nuget package.
// (full namespaces and types only shown here for disambiguation)
Polly.Caching.MemoryCache.MemoryCacheProvider memoryCacheProvider 
   = new Polly.Caching.MemoryCache.MemoryCacheProvider(System.Runtime.Caching.MemoryCache.Default);

// Or (1b): Create a MemoryCacheProvider instance in .NET Core / .NET Standard.
// (full namespaces and types only shown here for disambiguation)
// NB Only if you want to create your own Microsoft.Extensions.Caching.Memory.MemoryCache instance:
Microsoft.Extensions.Caching.Memory.IMemoryCache memoryCache 
   = new Microsoft.Extensions.Caching.Memory.MemoryCache(new Microsoft.Extensions.Caching.Memory.MemoryCacheOptions());
Polly.Caching.MemoryCache.MemoryCacheProvider memoryCacheProvider 
   = new Polly.Caching.MemoryCache.MemoryCacheProvider(memoryCache);

// (2) Create a Polly cache policy using that Polly.Caching.MemoryCache.MemoryCacheProvider instance.
var cachePolicy = Policy.Cache(memoryCacheProvider, TimeSpan.FromMinutes(5));

// Or (1c): Configure by dependency injection within ASP.NET Core
// See https://docs.microsoft.com/en-us/aspnet/core/performance/caching/memory
// and https://docs.microsoft.com/en-us/aspnet/core/fundamentals/dependency-injection#registering-your-own-services

// (In this example we choose to pass a whole PolicyRegistry by dependency injection rather than the individual policy, on the assumption the webapp will probably use multiple policies across the app.)

// For example: 
public class Startup
    public void ConfigureServices(IServiceCollection services)
        services.AddSingleton<Polly.Registry.IPolicyRegistry<string>, Polly.Registry.PolicyRegistry>();
        // ...

    public void Configure(..., IPolicyRegistry<string> policyRegistry, IMemoryCache memoryCache)
        Polly.Caching.MemoryCache.MemoryCacheProvider memoryCacheProvider 
            = new Polly.Caching.MemoryCache.MemoryCacheProvider(memoryCache);
        var cachePolicy = Policy.Cache(memoryCacheProvider, TimeSpan.FromMinutes(5));
        policyRegistry.Add("myCachePolicy", cachePolicy);
        // ...

// In a controller, inject the policyRegistry and retrieve the policy:
// (magic string "myCachePolicy" only hard-coded here to keep the example simple!) 
public MyController(IPolicyRegistry<string> policyRegistry)
    _cachePolicy = policyRegistry["myCachePolicy"];
    // ...

For many more configuration options and usage examples of the main Polly CachePolicy, see the main Polly readme and deep doco on the Polly wiki.
