This is in my web.config of a Azure WCF Service Project.

<dataCacheClient name="default">
  <hosts>
    <host name="***.cache.windows.net" cachePort="22233" />
  </hosts>
  <securityProperties mode="Message">
    <messageSecurity authorizationInfo="***"></messageSecurity>
  </securityProperties>
</dataCacheClient>

Here is the use of it in code

string GetCache()
{
    DataCacheFactory cacheFactory = new DataCacheFactory();
    DataCache cache = cacheFactory.GetDefaultCache();
    cache.Put("item", "value");
    var r = (string)cache.Get("item");
    return r;
}

Also this is the last achievement i need to have them all so please help.  Thanks so much.
