WCF is a newer technology that is a viable alternative in many instances. ASP is great and works well, but I personally prefer WCF. And you can do it in .Net 4.5.

Create a new project. Right-Click on the project in solution explorer, select "Add Service Reference"

Create a textbox and button in the new application. Below is my click event for the button:

private void btnGo_Click(object sender, EventArgs e)
    {
        ServiceReference1.Service1Client testClient = new ServiceReference1.Service1Client();
        //Add error handling, null checks, etc...
        int iValue = int.Parse(txtInput.Text);
        string sResult = testClient.GetData(iValue).ToString();
        MessageBox.Show(sResult);
    }

And you're done.
