EntityFramework Core引用导致编译器错误

Question

我已将entityframework核心参考添加到我的完整框架核心webapi项目中，但它会导致错误。我在Startup.cs中注册了db上下文，如下面的屏幕截图所示。当我尝试运行它（使用dotnet run）时，代码会抛出错误！错误如下所示，有什么我做错了吗？

非常感谢，任何帮助表示赞赏。

分界线

services.AddDbContext<DbContext1>(options => options.UseSqlServer(Configuration.GetConnectionString("DbContext1")));

错误

>dotnet run
Project something (.NETFramework,Version=v4.6) will be compiled because inputs were modified Compiling something for .NETFramework,Version=v4.6

Compilation succeeded.

如果它仍在发生，我刚刚在NuGet管理器中升级Microsoft.Extensions.Logging，所以它帮助了我。
