Adding a Web Service in .NET...
You need to understand the wCF vs ASMX first, and for that I will point you to one of my answers regarding the subject.
What is the difference between an asp.net web method and a wcf service?
after knowing that, you will know that ASMX Web Services require IIS to live, and for that, you will only find the template of a ASMX Web Service in a Web site project.
You can off course create a WCF Service, and you can host it anywhere you want, in IIS, as a Windows Service, as a TCP/IP service, as ... everywhere :)
Witch I thing is what you are after.
There are plenty of Video Tutorials outthere regarding WCF Services so you can see how to make and consume one.
For a webservice to run, you need it to run under IIS, which your windows app isn't.
Do you want another app to be able to call a SOAP interface when your application is running? Then in that case I think you may want your app to start a windows service.
