运行Window Arzure 项目，报如下错误：
Windows Azure Tools: Failed to initialize Windows Azure storage emulator. Unable to start Development Storage. Failed to start Development Storage: the SQL Server instance ‘localhost\SQLExpress’ could not be found. Please configure the SQL Server instance for Development Storage using the ‘DSInit’ utility in the Windows Azure SDK.
1 如果本地已安装Sql server, 请检查SQLEXPRESS实例是否已启动， 如果没有启动，启动即可
2 运行Windows Azure SDK Command Prompt
C:\Program Files\Microsoft SDKs\Windows Azure\Emulator\devstore>dsinit /sqlinstance:sqlexpress
