我收到此错误：
从RC2迁移到ASP.NET Core 1.0后在ConfigureServices中调用“ services.AddSession（）”时出错
这是详细信息：
错误信息：

最佳答案
这是一个版本问题。检查project.json文件。我在下面给出了代码：
"Microsoft.ApplicationInsights.AspNetCore": "1.0.0",
"Microsoft.AspNetCore.Authentication.Cookies": "1.0.0",
"Microsoft.AspNetCore.Diagnostics": "1.0.0",
"Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.0.0",
"Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.0.0",
"Microsoft.AspNetCore.Mvc": "1.0.1",
关于asp.net-core - System.TypeLoadException无法加载类型'Microsoft.Extensions.DependencyInjection.ServiceCollectionExtensions'，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/38210085/
