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",

System.TypeLoadException无法加载类型＆＃39; Microsoft.Extensions.DependencyInjection.ServiceCollectionExtensions＆＃39;
