Debug a web service linked with an application on XP machine

I'm new to web services and I'm stuck with a problem. I have code for a client application and code for a web service both of them written on C# The client application is using this web service to call a procedure I have created an IIS(5.1) v开发者_如何学编程irtual directory on my machine and I want to go through the client application into the web service debugging to see the web service procedure how is working. I have XP as O.S. and use visual studio 2003. Thanks

you can open the webservice solution in VS 2003 and follow debug => attach to process and attach aspnet_wp.exe or w3wp.exe. If you want to debug through your client application, both your client application and webservice should be opened in the same VS 2003 instance, and you should attach both your client application and aspnet_wp.exe
