using System.Web.Services;

/// <summary>
/// Summary description for Services
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// 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 Services : System.Web.Services.WebService
{

[WebMethod]

public string USD_Prices()
{
    string UnitedStateDollar;
    using (var Entity = new DataModel.DBEntities())
    {
        var UsdPrice = Entity.TblExchange.OrderByDescending(Exchange => Exchange.Id).Select(p => p.USDSell).Take(1).ToList();

Add this in your web config.

<configuration>
    <system.web>
    <webServices>
        <protocols>
            <add name="HttpGet"/>
            <add name="HttpPost"/>
        </protocols>
    </webServices>
    </system.web>
</configuration>

There's no problem. Web services don't have forms. In order to use a web service from .NET, you add the as a service references and call them from client code.

Old-style ASMX services had a form you could use for demonstration purposes where you could enter some simple values and call POST to get a result from the service. This was removed in WCF services because real-world web services have complex parameters that can't be handled by a simple form.

It would be far better to create a WCF service instead of an ASMX service. WCF services are more compliant, performant, flexible, scaleable (etc etc).

In any case, you can call you service from another client by adding a Service Reference to your project. This will create a proxy class that will expose the service's parameters as objects and the endpoints as methods on a client object.
