web services resources recommendations

hello

i am developing an ASP.NET/C# application for my company. they now want me to design and implement a web services solution which will enable our system to effectively synchronise data and offer method calls with a different company's system.

i am new to web services and i know i need to read about XML, XLST, SOAP, UDDI (?) etc. I have been on Amazon and the number of books available is mind boggling.

can anyone offer me recommendations please for books and free internet resources where I can gain a good understanding about web services, in particular how XML and ASP.NET can work together.

thanks.A very good way to start learning about WebServices is theWeb Services Developer Center

hope this helps,
sivilian
