1、通過nuget/修改project.json引用  

2、引用存儲session的媒介，如內存、數據庫、redis等

 "Microsoft.AspNetCore.Session": "1.1.0-*",

    "Microsoft.Extensions.Caching.Memory": "1.1.0-*",

    "Microsoft.Extensions.Caching.Redis": "1.1.0-*",

    "Microsoft.Extensions.Caching.SqlServer": "1.1.0-*",

3、修改startup.cs

public void ConfigureServices(IServiceCollection services)
        {
            services.AddDistributedMemoryCache();
            services.AddSession();
            services.AddMvc();
        }

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            app.UseSession();

4、使用

Context.Session.GetString("UserName")
