You can create an WCF REST web service by configuring your endpoint to use a webHttpBinding
as seen in this in-depth tutorial:

Here is another open source web services framework that simplifies creating XML and JSON REST web services without requiring any extra configuration.
Edit: Added link to good article articulating the spirit of REST:
