EF 模型未在 azure 中更新？
EF model not updated in azure?
我已经使用 SQL 数据库和 EF（db-first）在 Azure 中设置了一个可用的 asp.net mvc6 网络应用程序。一切正常，直到我向数据库中添加了一些列和表。重新生成模型后，在我的本地计算机上一切仍然正常，但是在发布应用程序并在 azure 中更新数据库（使用 SQLAzureMW）后，模型中似乎不存在新列，因为我收到错误"invalid column name" 表示 10 列。使用未更改表格的页面仍在工作
在 visual studio 中连接到我的 Azure 帐户后，我在我的 Web.config 文件的远程视图中检查了我的连接字符串，它们对我来说似乎没问题：
<add name="DefaultConnection"
connectionString="Data Source=tcp: <hidden>.database.windows.net,1433;Initial Catalog=datatheek7;User ID=<hidden>;Password=<hidden>" providerName="System.Data.SqlClient" />
<add name="datatheek7Entities"
connectionString="metadata=res://*/Models.datatheek7Entities.csdl|res://*/Models .datatheek7Entities.ssdl|res://*/Models.datatheek7Entities.msl;provider=System.Data.SqlClient;provider connection string="Data Source=tcp:<hidden>.database.windows.net,1433;Initial Catalog=datatheek7;User ID=<hidden>;Password=<hidden>;" providerName="System.Data.EntityClient" /></connectionStrings>
当我在 SSMS 中连接到 Azure 数据库时，新添加的列和表也是可见的，并且我可以在 Azure 的模型文件夹中看到正确的 edmx.diagram 文件。在那个文件夹中，我还看到了另一个带有项目名称的 edmx.diagram（在我的例子中是 datatheek2.edmx.diagram）。因为我怀疑该应用程序仍在使用我刚刚删除的初始 edmx 图，但它没有任何区别。
有人有什么想法吗？将不胜感激！

我解决了我的问题！
我在本地向数据库添加了一些测试表并更新了模型，然后再次发布到 Azure。这些表在关联视图中显示得非常好，因此模型确实更新了，问题应该出在数据库模式中。我在 SSMS 中提取了完整的数据库，我在 azure 上发布的版本和我在本地发布的版本似乎有些不同，真的不知道为什么。在 azure 中删除完整的数据库并发布本地版本后，一切正常。
