使用 VS2017 在 ASP.Net Core 1.1 中添加“AddSession”时出现错误。

'IServiceCollection' does not contain a definition for 'AddSession'and no extension method 'AddSession' accepting a first argument oftype 'IServiceCollection' could be found (are you missing a usingdirective or an assembly reference?)

我知道这有点晚了，但是您是否尝试从 nuget 安装 Microsoft.AspNetCore.Session 包？

https://www.nuget.org/packages/Microsoft.AspNetCore.Session/

在 Visual Studio 中:
安装包 Microsoft.AspNetCore.Session -Version 1.1.2(在我的情况下)

它对我有用!
