Question

我已经下载了Kigg Asp.net入门套件项目。

然后我将其转换为VS.Net 2010项目，它成功地完成了所有工作。

然后我运行创建kigg数据库并添加了默认数据。（来自源文件附带的脚本文件）

我的开发环境 - 使用VS.Net 2010和SQL Server 2008的64位Win 7操作系统

但我仍然遇到这个错误。

The underlying provider failed on Open.

"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
