As recommended in many of your recent posts, learn .NET Core fundamentals.   Any beginning level tutorial will have this information or reading the .NET Core fundamentals documentation.

var response = Request["g-recaptcha-response"];

Request["g-recaptcha-response"] has been replaced by model binding but the syntax still works.  

https://docs.microsoft.com/en-us/aspnet/core/mvc/models/model-binding?view=aspnetcore-5.0

HttpContext.Request.Form["key"]

 string activationProtocol = Request.Url.Scheme;

HttpContext.Request.Scheme

kalvakrishna

model.ActivationUrl = Url.Action(String.Empty, "Activate", routeValues: null, protocol: activationProtocol);

Works the same in .NET 5 (Core).

kalvakrishna

foreach (String key in Session.Keys)
            {
                _logger.Debug(String.Format("Session Key={0}, Value={1} ", key, Session[key]));
            }

Accessing Session is cover extensively in your recent post(s).

• getting error "Cannot apply indexing with [] to an expression of type 'HttpRequest'" for   

var response = Request["g-recaptcha-response"];

• No overload for method 'Action' takes 4 arguments    

string activationUrl = Url.Action(String.Empty, "ForgotPasswordActivate", routeValues: null, protocol: activationProtocol);

• string activationProtocol = Request.Url.Scheme;

  Please let me know the converted code in .NET Core

You did not follow the instructions or read the doc???

HttpContext.Request.Form["key"]

• No overload for method 'Action' takes 4 arguments    

string activationUrl = Url.Action(String.Empty, "ForgotPasswordActivate", routeValues: null, protocol: activationProtocol);

The overload is... 

string activationUrl = Url.Action(String.Empty, "ForgotPasswordActivate", null, activationProtocol);
