I Know Cookieless SessionState on  ASP.NET 2.0 , 
#Web.Config
<system.web>
<sessionState cookieless="true"/>
</system.web>

Also I know normal Session Future on ASP.NET CORE 2.0

Import Microsoft.AspNetCore.Session

And Change Startup.cs

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

}

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