I am runnig this application on windows 10.

What I have tried:

i Just created a simple "Empty ASP.Net web application" and added a web services named as "HelloWebService.asmx" within this file created a single method called as "GetMessage" with single parameter as follows:
public class HelloWebServices : System.Web.Services.WebService
        public string Getmessage( string name)
            return "Hello World " + name;

After that i created one more "Empty ASP.NET Web Application" with the name "HelloWebClient" and added to this a "WebForm1.aspx" with the following code to call the "Getmessage" web method in the "HelloWebServices".
public partial class WebForm1 : System.Web.UI.Page
        protected void Button1_Click(object sender, EventArgs e)
            HelloWebService.HelloWebServicesSoapClient client = new 

            Label1.Text = client.Getmessage(TextBox1.Text);

After that, i add a ServiceReference "HellowWebservice" to the "HelloWebClient".

Now i am running the application and click on the "Get Message" button and i am getting the below error. please advise and help me to solve this issue.

The exact error is in the line : 120 return base.Channel.Getmessage(request);
Server Error in '/' Application.

either a firewall issue or the following might help.

Check your .config files, mostly this error is caused by a wrong port number, or incorrect name of the PC (which should be localhost if you are testing everything on one PC).
