无法加载文件或程序集'System.Data.SqlClient，版本= 4.2.0.2，区域性=中性，PublicKeyToken = b03f5f7f11d50a3a'.找到的程序集的清单定义与程序集引用不匹配. (来自HRESULT的异常:0x80131040)

何时使用VSTS将项目发布到Azure App Service?当然，它完全可以在我的机器上正常工作！

when the project is published with VSTS to Azure App Service? And of course it perfectly works on my machine!

昨天所有这些都奏效了.但是今天我决定将软件包更新为:

All this worked yesterday. But today I decided to update packages to:

<PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.6" />
<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.0.3" />

推荐答案

降级为

<PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.6" />

，一切又恢复正常！今天输了4个小时！！！

and everything works again! Lost 4 hours today!!!
