这个坑，今天整了一天，我添加了Microsoft.AspNetCore.Mvc.Versioning包，结果发布到服务器，我复制了dll过去出现了一直找不到加载不成功的问题
Startup.ConfigureServices一直加载不成功，出错如下:
Application startup exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.AspNetCore.Mvc.Versioning, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. 系统找不到指定的文件。 File name: 'Microsoft.AspNetCore.Mvc.Versioning, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' at SC.API.Startup.ConfigureServices(IServiceCollection services) --- End of stack trace from previous location where exception was thrown --- at Microsoft.AspNetCore.Hosting.ConventionBasedStartup.ConfigureServices(IServiceCollection services) at Microsoft.AspNetCore.Hosting.Internal.WebHost.EnsureApplicationServices() at Microsoft.AspNetCore.Hosting.Internal.WebHost.Initialize() --- End of stack trace from previous location where exception was thrown --- at Microsoft.AspNetCore.Hosting.Internal.WebHost.BuildApplication()
后面仔细发现，添加了新的nuget包，发布后，在发布地址的目录下 找到这个文件
*.deps.json 此文件会新增nuget包的依赖关系，比较后发现
解决方法:除业务DLL以外，还需要复制此json文件覆盖，使得项目可以加载nuget包，不然netcore 无法映射加载新的包
