Using Windows Server AppFabric Caching Service

AppFabric Caching Service is a distributed cache platform for in-memory caches spread across multiple systems, developed by Microsoft. It is one of Microsoft's AppFabric's Services. In its early stages of development, it was referred by a code name Velocity.

Some useful PowerShell commands:

Get-Cache [-HostName] [-PortNumber]	Without any parameters, this will list information about all caches and regions on a cluster. Otherwise on a specified cache host.
Get-CacheHost [-HostName] [-PortNumber]	Sees all of the cache services status in a cluster. If the parameters are used then of the host.
New-Cache	Creates a new named cache. It has a few other parameters that are optional.
Get-CacheAllowedClientAccounts	Lists all accounts that have permission.
Grant-CacheAllowedClientAccount -Account "DOMAINNAME\username"	Grants permission for an account.
Stop-CacheHost	Stops the specified cache service. The exception message that you will see when it is down: ErrorCode:SubStatus:There is a temporary failure. Please retry later.
Start-CacheCluster	Starts all cache services in the cluster.
Start-CacheHost	Starts the specified cache service.
Restart-CacheCluster	Restarts all cache services in the cluster.

GUI admin tool
There is also a GUI admin tool for managing the cache service: http://mdcadmintool.codeplex.com


Coding guide
To use the cache service in the codes, we need to include Microsoft.ApplicationServer.Caching.Client and Microsoft.ApplicationServer.Caching.Core to the project's References.

Examples of how to add an object to cache using Add method, Put method or Item property:

A simple codes example of how to use the cache service:

DataCacheFactory factory = new DataCacheFactory();
DataCache cache = factory.GetCache("test");

string key = "key1";
string value = "value1";
cache.Put(key, value);

var value = cache.Get(key);

For a thorough example that uses various features of AppFabric caching service, look at the CacheAPISample project of this example projects from Microsoft. Alternatively download the codes from here and run it as a console application.
