Question

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起作用，我修改它以使我的部署适合Azure，但后来我收到错误。

以下是适用于我本地计算机的原始连接字符串：

<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Azure的已修改连接字符串：

<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" />

有人可以告诉我我做错了什么，我错过了什么，让它发挥作用？

提前致谢。

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。主要是你添加了一个“火器”表，但是azure表不包含这个表
