解决Window Azure: Failed to start Development Storage: the SQL Server instance ‘localhostSQLExpress’

在运行window azure项目时，如果遇到以下错误：

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.

您可以按照以下步骤解决此问题：

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，请启动它。

2. 运行Windows Azure SDK Command Prompt。
