Question

我正忙着使用实体框架创建一个.net mvc 4 Web应用程序。

如果我更改某个控制器并重新构建解决方案，则网页会加载并加载，并最终表示连接到数据库时出错。

建立与SQL Server的连接时发生与网络相关或特定于实例的错误。服务器未找到或无法访问。验证实例名称是否正确，以及SQL Server是否配置为允许远程连接。（提供程序：SQL网络接口，错误：26 - 查找指定的服务器/实例时出错）

然后我关闭并重新打开浏览器，页面加载正常。

注意：我正在通过IIS运行该站点，如果我在调试模式下运行它也会加载

任何人都有某种想法可以解释为什么会发生这种情况？

在我看来，你在SQL部分改变了一些东西。我猜你改变了SQL查询或连接。当我在MVC视图中进行更改时，我遇到了同样的情况。我需要重新加载浏览器，因此会加载更改。我建议你展示一些图片，让你的问题更加详细。希望它可能有所帮助。
