Adding a Session Value in a Controller

I'm trying to add value to the Session object in a Controller like this:

Request.HttpContext.Session.SetString("key, "value")

But I get the next error: The session cannot be established after the response has started.

How can I add a value to the Session object from a controller?

Thank you.

Edit:

This is the code:

public IActionResult SetValue()
{
     Request.HttpContext.Session.SetString("user", "aam3");
     return View();
}

OK, I found the problem, I had a custom middleware before the App.UseMvc statement, in that middleware I had the line await Context.Response.WriteAsync("Testing Middleware"), that line inmedaitly started the response, for that reason I wasn't able to change the Session later in the controller.

Thank you.

Please try this. It is working for me and I am using CTP 6.

public IActionResult Index()
        {
            Context.Session.SetString("key", "value");
            return View();
        }

Also to be more sure it is important that what you have done in Startup.cs file.
