Question

i get an error when i try to access HttpContext.Current from a controller.
I want to get the session to add some session specific data, and this gives me a problem:

var a = HttpContext.Current.Session;

The error, allegedly is that ‘System.Web.HttpContextBase’ does not contain a definition for ‘Current’.

when i try to access HttpContext.Current from a controller

You should never use HttpContext.Current.

Simply use the Session property to access the session:

public ActionResult Index()
{
    Session["foo"] = "bar";
    ...
}

The reason for the error you are getting is because the controller class already has a property called HttpContext so when you write HttpContext.Current it is the property that is used and not the static Current property on the HttpContext class.
