所以我打开了一些在大约2个月内没有被触及过的代码。
上次打开应用程序时，所有单元测试都通过了。现在没有代码更改，我的所有数据单元测试都失败，并出现以下错误：
初始化方法 PerTrac.Pictor.Data.Test.RequestLogRepositoryShould.CreateLog扔了 例外。 System.Data.EntityException：System.Data.EntityException： 底层提供程序在Open上失败。 ---＆GT; System.Data.SqlClient.SqlException：连接成功 与服务器建立，但在此期间发生错误 登录前握手。 （提供者：SSL提供者，错误：0 - 等待 操作超时。）---＆gt; System.ComponentModel.Win32Exception：The 等待操作超时。
我意识到存在类似的问题，但这些解决方案对我的情况没有任何影响。
是否有人在实体框架和SQL Azure中遇到此错误？
我应该注意，我可以从SSMS连接，使用相同的凭据没有问题。我没有在禁用的协议上设置强制加密，我已经多次重置本地IIS。

您的计算机上安装的某些应用程序很可能使用不推荐的网络协议来拦截网络流量。希望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＆gt;＆gt; winsock.txt 然后记事本winsock.txt 打开文件。
查看返回的每个 Winsock目录提供程序条目。如果 Service Flags 值设置为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位清零（未设置），则它是非IFS BSP或LSP，可能是个问题。尝试禁用此应用程序，然后告诉我们它是否有效。
在查看文本文件结果时忽略“名称空间提供者条目”。他们不是问题。
下面是netsh WinSock Show Catalog文件输出的清洁系统示例。

答案 1 :(得分：5)
了解问题的关键是提供商，在您的情况下，它是“SSL提供商”，主要问题是连接超时。如果问题与“TCP提供商”有关，可能有几个与网络相关的原因，但在您的情况下，它是连接框架内的安全相关问题。
调查此问题的下一步是，在同一台计算机上，您可以从SSMS连接到相同的SQL数据库，但不能从IIS连接，这意味着IIS应用程序进程无法获取正确的证书来创建SSL隧道来创建成功的联系。您可能有一些日志写入系统事件日志，所以请检查那里。
因为您正在使用Entity Framework并依赖于EF版本，所以连接字符串中有一些更改，因此请验证这是否是您所拥有的：
<add name="MyDatabaseModelEntities" connectionString="metadata=res://*/MyDBModel.csdl|res://*/MyDatabaseModel.ssdl|res://*/MyDatabaseModel.msl;provider=System.Data.SqlClient;provider connection string="data source=abcdefg123.database.windows.net;initial catalog=MyDatabase;persist security info=True;user id=MyDatabaseUser@abcdefg123;password=p@$$w0rd;multipleactiveresultsets=True;Trusted_Connection=False;Encrypt=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
最后，如果您使用的是EF 4.3.1并连接到SQL数据库，请查看this文章并检查您是否有类似的配置。
