C# AppFabric 1.0错误服务器集合不能为空

运行简单的Windows Server App Fabric 1.0演示控制台应用程序时，我遇到以下错误：

ErrorCode<ERRCA0021>:SubStatus<ES0001>:Server collection cannot be empty.

ErrorCode:SubStatus:Server集合不能为空。

请帮帮我。。我错过了什么。。？？我在互联网上到处查看，似乎没有任何东西能解决这个问题。谢谢

我的申请如下：

static void Main(string[] args)
{
    var factory = new Microsoft.ApplicationServer.Caching.DataCacheFactory(); <--- *** Error here

    var cache = factory.GetDefaultCache();
    var key = "mykey";
    var obj = cache[key];
    if (obj == null)
    {
        cache[key] = "I am data for caching";
    }
    obj = cache[key];
    Console.WriteLine(obj);
    Console.Read();
}

static void Main（字符串[]args）
{
var factory=new Microsoft.ApplicationServer.Caching.DataCacheFactory（）；我更新了我的appconfig，如下所示，它运行正常
