HttpContextBase namespace could not be found

Question

public string GetCartId(HttpContextBase context)
{
    if (context.Session[CartSessionKey] == null)
    {
        if (!string.IsNullOrWhiteSpace(context.User.Identity.Name))
        {
            context.Session[CartSessionKey] =
                context.User.Identity.Name;
        }
        else
        {
            // Generate a new random GUID using System.Guid class
            Guid tempCartId = Guid.NewGuid();
            // Send tempCartId back to client as a cookie
            context.Session[CartSessionKey] = tempCartId.ToString();
        }
    }

    return context.Session[CartSessionKey].ToString();
}

Any help on the work around with HttpContextBase in asp.net core? above is my sample code am working on to create a shopping cart.

You can use HttpContextBase abstractContext = new System.Web.HttpContextWrapper(context); — Tomato32, Jun 27 '17 at 08:30

I don't know if it's important or not, but guid's aren't guaranteed to be random, they are only guaranteed to be unique. — Enigmativity, Jul 24 '17 at 07:22

There is no HttpContextBase in ASP.NET Core. HttpContext is already an abstract class (see here) which is implemented in DefaultHttpContext (see GitHub). Just use HttpContext.

`public string GetCartId(HttpContext context) ` This worked. – Abel Masila Jun 27 '17 at 08:54

I had to modify like below

public string GetCartId(HttpContext context)
{
    if (context.Session.GetString(CartSessionKey) == null)
    {
        if (!string.IsNullOrWhiteSpace(context.User.Identity.Name))
        {
            context.Session.SetString(CartSessionKey, context.User.Identity.Name);
        }
        else
        {
            var tempCartId = Guid.NewGuid();
            context.Session.SetString(CartSessionKey, tempCartId.ToString());
        }
    }

    return context.Session.GetString(CartSessionKey);
}

It may help someone :)

using net5 and autofac I found the following solved my needs. something feels a bit hackish about this and I will update if this solution evolves.

add binding for HttpContextAccessor to autofac

      using Microsoft.AspNetCore.Http;
      // ...
      builder.RegisterType<HttpContextAccessor>().As<IHttpContextAccessor>()
          .AsSelf()
          .SingleInstance();

add dependency to HttpContextAccessor in

private readonly HttpContextAccessor _httpContextAccessor;

access current context _httpContextAccessor.HttpContext
