.net - 使用.NET 4.5连接到SQL Server Azure时发生握手异常

转载作者：行者123 更新时间：2023-12-02 07:42:37

所以我打开了一些大约2个月没有碰过的代码。

上次我打开应用程序时，所有单元测试都通过了。现在，如果没有代码更改，我的所有数据单元测试都会失败，并出现以下错误:

Initialization method PerTrac.Pictor.Data.Test.RequestLogRepositoryShould.CreateLog threw exception. System.Data.EntityException: System.Data.EntityException: The underlying provider failed on Open. ---> System.Data.SqlClient.SqlException: A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The wait operation timed out.) ---> System.ComponentModel.Win32Exception: The wait operation timed out.

我意识到存在与此类似的问题，但这些解决方案对我的情况没有任何影响。

有没有人在 Entity Framework 和 SQL Azure 上遇到过这个错误？

我应该注意，我可以使用相同的凭据从 SSMS 进行连接，没有任何问题。我没有对禁用的协议(protocol)设置强制加密，并且我已多次重置本地 IIS。

最佳答案

您的计算机上很可能安装了某些应用程序，该应用程序使用已弃用的网络协议(protocol)来拦截网络流量。正确的解决方案是禁用或卸载这些应用程序。

运行命令行命令netsh WinSock Show Catalog>>winsock.txt，然后运行notepad Winsock.txt打开该文件。

查看返回的每个Winsock 目录提供程序条目。如果服务标志值设置了 0x20000 位，则提供程序使用 IFS 句柄并且可以正常工作。如果“服务标志”0x20000 位被清除(未设置)，则它是非 IFS BSP 或 LSP，并且可能是一个问题。尝试禁用此应用程序，然后让我们知道它是否有效。

查看文本文件结果时，请忽略“ namespace 提供程序条目”。他们不是问题。

下面是我的干净系统的 netsh WinSock Show Catalog 文件输出的示例。
