You need provide more details about your codes which doesn't work. But basically you can refer to below steps:

  1. Add ASP.NET Core 2.0 web api application .
  2. Install Microsoft.AspNetCore.Session NuGet package .

  3. Modify your Startup.cs, call AddDistributedMemoryCache and AddSession methods in ConfigureServices function , and add UseSession method in Configure function :

    public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    services.AddDistributedMemoryCache();
    services.AddSession();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    app.UseSession();
    app.UseMvc();
}

  4. Get/Set session in controller(using Microsoft.AspNetCore.Http;) :

    [HttpGet("setSession/{name}")]
public IActionResult setsession(string name)
{
    HttpContext.Session.SetString("Name", name);
    return Ok("session data set");
}
[HttpGet("getSession")]
public IActionResult getsessiondata()
{
    var sessionData = HttpContext.Session.GetString("Name");
    return Ok(sessionData);
}
  5. Then you could make api call to http://localhost:xxxxx/api/ControllerName/setSession/derek to set session , and call to http://localhost:xxxxx/api/ControllerName/getSession to get session data .
