2. Name the folder api.
3. Add a new Web Service (ASMX) to this folder named ScriptLinkService.asmx. (Select Show All Templates if needed.)
4. Implement the GetVersion and RunScript methods as shown below.

/api/ScriptLinkService.asmx

using RarelySimple.AvatarScriptLink.Objects;
using System.Web.Services;

namespace ScriptLinkHelloWorldDemo.api
{
    /// <summary>
    /// Summary description for ScriptLinkService
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    public class ScriptLinkService : System.Web.Services.WebService
    {
        [WebMethod]
        public string GetVersion()
        {
            return "0.1.0";
        }

        [WebMethod]
        public OptionObject2015 RunScript(OptionObject2015 optionObject, string parameter)
        {
            return optionObject.ToReturnOptionObject(ErrorCode.Alert, "Hello World!");
        }
    }
}

Run Application

1. Press F5 to run the service in your default browser.

Congratulations! You should now see your API showing in the browser and are ready to make the API calls.

You can get the WSDL for import to myAvatar by appending the address with ?WSDL. For example, https://localhost:44376/api/ScriptLinkService.asmx?WSDL.
