I need to create a SOAP Web Service in C#.
I've done this in the past in Java with eclipse, but couldn't really find something that is SOAP specific when creating a new Web Service project in VS2008.
I need some kind of guidance on how to start this.
Also, the intended client will be implemented in Java,
are there known compatibility issues with this?
Thanks
It doesnt matter what the client is, that's the nature of web services (interopable communications).
You can either create a 'legacy' ASP.NET Web Service (ASMX), or a WCF Service.
By default, ASMX web services (or WCF Services with regular HTTP endpoints) transmit XML over HTTP (SOAP).
If you're writing something from scratch, consider WCF over ASMX - more flexbility and security.
