small web service

Question

At my company I am told that I need to setup a web service with an 'xsd' file I will be receiving tomorrow morning. I have a visual studio.net 2010 professional version development software to work with and I have experience using C# 2010.

Since I have not setup a web service before, I am wondering how to setup the web service from scratch? All I want to do is have the web service that only works with the *.xsd file.

Thus can you tell me and/or point me to a reference on how to setup this web service?
