asp.net-core - System.TypeLoadException 无法加载类型 'Microsoft.Extensions.DependencyInjection.ServiceCollectionExtensions'

Question

我收到这个错误:

Error when call "services.AddSession()" in ConfigureServices after migrate from RC2 to ASP.NET Core 1.0

详情如下:

Error Message: System.TypeLoadException Could not load type 'Microsoft.Extensions.DependencyInjection.ServiceCollectionExtensions' from assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'

是版本问题。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",
