使用EF将ASP.NET Core应用程序发布到Azure Web App时，连接SQL Server时会出现此错误：

我甚至尝试将“Microsoft.EntityFrameworkCore.Tools”的“type”属性更改为“platform”，因此它将复制它的dll，还尝试将“System.Data.SqlClient.dll”复制到/ wwwroot / bin文件夹重新启动应用程序，但仍然得到相同的错误。
在我的本地机器上运行
答案 0 :(得分：5)
<强>解决！
azure web apps在Windows 2012 r2上运行，因此我需要设置win7运行时并将发布设置更改为win7-x64：
"runtimes": {
"win10-x64": {},
"win7-x64": {}
},
答案 1 :(得分：0)
我设法将此调整到我的场景并使代码正常工作。上面的设置对我来说并不起作用 - 我必须确保手动删除网站上的所有文件，然后使用win7-x64部署
