我已经安装了 Windows Server AppFabric，现在我什至无法运行最基本的 WCF 工作流服务应用程序。我已经完成了持久性存储、监视器和缓存的配置和设置数据库，它们工作正常。
所以我把它剥离了，只是创建并运行了一个空的 WCF 工作流服务应用程序。当我单击 Service1.xaml 文件时，出现以下错误。
我已经检查了数据库，并且我拥有对所有数据库的 dbowner 访问权限（在此处替换了我的真实登录详细信息）。
我正在使用带有 .NET 4 更新 1 的 VS2010。
“/”应用程序中的服务器错误。
无法打开登录请求的数据库“AppFabricPersistenceDB”。登录失败。用户“mydomain\myusername”登录失败。说明：执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。
