症状：
安装了Azure SDK后，新建一个Web Role，F5启动程序，弹出一个Storage Emulator Initialization对话框显示以下错误信息：
==============================================
Attempting to use server specified.
User specified an instance through /server or /sqlInstance options.
Probing Failed. Retrying probe for localDB
Probing SQL Instance: '(localdb)\v11.0'.
==============================================
原因：
没有配置本地SQL Server信息。
解决方案：
1. 打开Windows Azure Command Prompt。
2. 运行命令dsinit /sqlInstance:your instance name
此后会弹出Storage Emulator Initialization对话框显示以下信息
==============================================
Added reservation for http://127.0.0.1:10000/ in user account username.

此时再F5，Azure project就可以工作正常了。
