Caching

Pavalisoft.Caching is an open source caching extension for .NET Standard written in C#, which provides single unified API for both MemoryCache and DistributedCache implementations.

The main goal of the Pavalisoft.Caching package is to make developer's life easier to handle even very complex caching scenarios and concentrate on functionality. It's additional feature CacheManager supports various cache providers and implements many advanced features which can be used in single project/application.

With Pavalisoft.Caching, it is possible to implement multiple layers of caching with multiple cache providers in one place, e.g. MemoryCache and DistributedCache, in just a few lines of code.

The below diagram explains the Pavalisoft.Caching API and its usage.

Add Pavalisoft.Caching to services. Also add the Pavalisoft.Caching.InMemory , Pavalisoft.Caching.MySql , Pavalisoft.Caching.Redis and Pavalisoft.Caching.SqlServer Cache store implementations to services based on usage.

...
//Import the below namespace to use InMemory and DistributedInMemory cache store implementations

//Import the below namespace to use SqlServer Cache Store implementation
using Pavalisoft.Caching.SqlServer;
...

namespace Pavalisoft.Caching.Sample

Use CacheManager methods to add, get, refresh and remove items in Cache.

// Add required using statements
using Pavalisoft.Caching;
using Pavalisoft.Caching.Interfaces;
using Microsoft.Extensions.Primitives;
using System;

namespace Pavalisoft.Caching.Sample
{
	public class CachingSample
	{
		private const string CachePartitionName = "FrequentData";		
		private readonly ICacheManager _cacheManager;
		public CachingSample(ICacheManager cacheManager)
		{
			_cacheManager = cacheManager;
		}

		public AppUser GetAppUser(HttpContext httpContext)
		{
			var userName = httpContext.User.Identity.Name;
			AppUser appUser;
			
			// Try to get the appUser from cache
			if (!_cacheManager.TryGetValue(CachePartitionName, userName, out appUser))
			{
				// If not available in Cache then create new instance of AppUser
				appUser = new AppUser(userName);

				// Add appUser object to Cache
				_cacheManager.Set(CachePartitionName, userName, appUser);                `
			}
			return appUser;
		}
	}
}

To use pavalisoft-cache tag helper, add the below to _ViewImport.cshtml

@addTagHelper *, Pavalisoft.Caching.TagHelpers

Use the pavalisoft-cache tag helper in the view wherever required.

Cache Store Configurations

The below classes are used for providing the StoreConfig to the respective CacheStores.

MemoryCacheOptions for InMemoryStore cache stores.
MemoryDistributedCacheOptions for MemoryDistributedCacheStore cache store.
RedisCacheOptions for RedisDistributedCacheStore cache store.
SqlServerCacheOptions for SqlServerDistributedCacheStore cache store.
MySqlCacheOptions for MySqlDistributedCacheStore cache store.

Serializers

Below are the list of serializers options available, which can be used to serialize and deserialize object from and to Distributed Cache Stores.

BinaryFormatter - Requires the classes decorated with SerializableAttribute to store into Distributed Cache Stores.
Newtonsoft.Json - Uses Newtonsoft.Json to serialize a class without SerializableAttribute.
