Method 1

If you’re running web application as startup project, try running web service in another debug instance.

You can do it by right-clicking on web service project, Debug -> Start new instance

Method 2

You should attach the debugger to w3wp (IIS process).

Here is a link that could help you.

Method 3

If you want to debug in local system, You can set multiple start up projects.
You can set multiple startup by Solution properties.
Hope this help

Method 4

Try to debug the service itself and see if it hits breakpoint. Just set the project that has service in it to be the main project and set the service to be the main start page.

If it doesn’t hit the breakpoint it probably didn’t load all the symbols. That happens if the project is set to, lets say, Release configuration and not Debug.

Method 5

Is the web service running on a remote computer , if so you need to setup remote debug for the web service.

Method 6

Can You please check that you add Service reference your web service or not other you can’t access your web service function. I am useing web service in my project like this it’s below

this is my web service code

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    [System.Web.Script.Services.ScriptService]
    public class JsonData : System.Web.Services.WebService
    {

        [WebMethod(Description = "")]
        [ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)]
        public StateData[] GetStateByCountryID(int ID)
        {
            StateData objStateData = new StateData();
            LMGDAL.db_LMGEntities dbData = new db_LMGEntities();                
            var data = (from con in dbData.tblStates
                        where con.State_CountryID == ID
                        select new StateData
                        {
                            StateID = con.StateID,
                            StateName = con.StateName
                        }).ToList();
            return data.ToArray();
        }

then i add Service reference to my asp.net web form

this code in my form

<script type="text/javascript">
    $(function () {

        $("#ddlCountry").change(function () {
            var countryID = $("#ddlCountry").val();
            $.ajax({
                type: "POST",
                url: "JsonData.asmx/GetStateByCountryID",
                contentType: "application/json; charset=utf-8",
                dataType: 'json',
                data: '{ID:"' + countryID + '"}',
                success: function (msg) {
                    var data = msg.d;
                    var stateData = "";
                    $.each(data, function (index, itemdata) {
                        stateData += "<option  value='" + itemdata.StateID + "' > " + itemdata.StateName + " </option>";
                    });
                    $("#ddlState").empty();
                    $("#ddlState").append("<option value='0'>-Select State-</option>");

                    $("#ddlState").append(stateData);
                },
                error: function () {
                    alert('Faild To Retrieve States.');
                }
            });
        });

I think this will help you
