.NET Caching Library

$ 99.95

The .NET Caching Library is the most flexible caching library available. It can be used in any type of application for the web, phone, or internet of things. It allows your application to have a memory cache with a backing cache of files, SQLite or SQL Server. The backing cache works in tandem with the memory cache to load items when it does not exist in the memory cache. Cached items can have different expiration policies in the memory cache and the backing cache. The memory cache is built on top of the System.Runtime.Caching and it has been enhanced to support regions. Data in the backing cache can be compressed and encrypted. The backing caches also support asynchronous save and remove. It supports all .NET project types including .NET Core, Mono, Xamarin iOS, Xamarin Mac, Xamarin Android, UWP, ASP.NET, WPF, Winforms, ASP.NET, Web Api, WCF, and Web Services. It supports all .NET languages including VB.NET and C#. Download the full list of features.

While it can be purchased separately, this product is also included in the Gold Suite. Gold Suite subscribers receive all product updates and all new products as part of a yearly subscription. It is the best value in the industry.



Feature Description
Familiar Method Names If you are familiar with the System.Runtime.Caching namespace in the .NET Framework, the methods in the .NET Caching Library have the same name; Add, AddOrGetExisting, Contains, Get, GetCacheItem, Remove, and Set.
Automatic Serialization/Deserialization Objects are automatically serialized and deserialized to the backing cache using binary serialization. No Serialization attribute is required on your objects.
Advanced Expiration Ability to have default expiration for memory and backing cache. Set individual expiration for each cache item saved for each cache. Cache items can have an absolute expiration or a sliding expiration.
Regions Store cached items in regions (including the memory cache).
Cache Key Generation Easily create cache keys based on parameters. Also supports unique reflection based key generation.
Advanced Removal Supports clearing cache items by Region, Wildcard, and Regular Expressions.
Cache Limits Ability to set the maximum cache items and maximum cache size for each provider. When the limit is reached, items are removed oldest first. Also supports removal by Least Recently Used or Largest Size.
Automatic Scavenging Backing cache providers automatically remove expired items on a configurable interval.
Asynchronous Operation Scavenging is performed asynchronously. Saving and removing can also be set to asynchronous. This includes asynchronous serialization, encryption and compression.
Extensible Easily create your own cache provider by inheriting from the BaseCacheProvider.
Documentation Industry standard formatted help and an easy to use demo is included.
Royalty Free Distribution Include with any .NET project royalty free. Deploy on an unlimited number of servers.

Example of loading a monthly sales report from the cache. It demonstrates attaching a file storage provider and loading and saving to the cache.
