Session in ASP.NET Core MVC-CodePudding

I am migrating an ASP.NET MVC application to ASP.NET Core MVC.

In ASP.NET MVC, I am using some Session variables to store or get values like:

Session["UserID"] = user.UserName;
Session["Role"] = role[0].ROLE_DESCRIPTION;
ViewData["LEVEL"] = Session["LEVEL"];

But after converting, I get an error:

The name 'Session' does not exist in the current context

Is there any other method in ASP.NET Core MVC to store or get values on those variables without changing the behavior?

You need to add session middleware in your configuration file

public void ConfigureServices(IServiceCollection services)  
{  
     //........
    services.AddDistributedMemoryCache();  
    services.AddSession(options => {  
        options.IdleTimeout = TimeSpan.FromMinutes(1);//You can set Time   
    });  
    services.AddMvc();  
} 

public void ConfigureServices(IServiceCollection services)
{
    //......
    app.UseSession();
    //......
}

Then in your controller, you can

//set session 

HttpContext.Session.SetString(SessionName, "Jarvik");  
HttpContext.Session.SetInt32(SessionAge, 24);

//get session

ViewBag.Name = HttpContext.Session.GetString(SessionName);  
ViewBag.Age = HttpContext.Session.GetInt32(SessionAge);
