Azure 中的实体框架连接字符串错误

【问题标题】：Entity Framework connection string error in AzureAzure 中的实体框架连接字符串错误

【问题描述】：

我目前在部署到 Azure 时遇到错误。 我直接从我的 web 配置文件中获取了连接字符串，该文件在本地测试时有效，我对其进行了修改以适应我对 Azure 的部署，但随后出现错误。

以下是在我的本地机器上工作的原始连接字符串：

<add name="DataEntities" connectionString="metadata=res://*/Models.FirearmModels.csdl|res://*/Models.FirearmModels.ssdl|res://*/Models.FirearmModels.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=(LocalDB)\v11.0;attachdbfilename=|DataDirectory|\Data.mdf;integrated security=True;connect timeout=30;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

以下是修改后的 Azure 连接字符串：

<add name="DataEntities" connectionString="metadata=res://*/Models.FirearmModels.csdl|res://*/Models.FirearmModels.ssdl|res://*/Models.FirearmModels.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=tcp:owm5115h08.database.windows.net,1433;Initial Catalog=diafirearmserver;User ID=userid;Password=userpass;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

谁能告诉我我做错了什么，我错过了什么，让这个工作？

提前致谢。

我到 Azure 的连接字符串：

【问题讨论】：

  • 在我的手机上，这个图像很糟糕。将例外剪切并粘贴到您的问题中，让所有相关人员的生活更轻松。
  • @BrendanGreen，我对截图的图像质量表示歉意。我用错误更新了原始帖子。
  • 在发布到 azure 时，您可以选择运行挂起的迁移，您是否选中了此复选框？还可以尝试连接到您的 sql 数据库并查看实际存在的内容（表）...
  • @Milen Pavlov，当我尝试连接到 Azure 中的数据库以查看实际存在的内容时，我收到以下错误：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。 （提供者：TCP 提供者，错误：0 - 不知道这样的主机。）不知道这样的主机
  • @MilenPavlov 我已经更新了原始帖子，以显示我原来的本地连接字符串，它工作正常，以及我修改后的 Azure 连接字符串。

标签： entity-framework azure connection-string


【解决方案1】：

此错误似乎表明您没有自动迁移/数据库迁移尚未在您的 azure 版本的数据库上运行。 主要是您添加了“枪支”表，但天蓝色表不包含此表

【讨论】：

  • 感谢@Batavia，现在我得到一个：不能用标准 DbConnection 覆盖此上下文的连接，因为原始连接是 EntityConnection
  • @saturobi360，我在这里面临同样的问题。您能否分享一下您为解决该问题所做的工作？谢谢
