Check out Thinktecture Cors objects, with those (nugettable) you can get full CORS support in WebApi without any code of your own.

Even with a correct CORS implementation I've had a really strange issue with IIS 7 that was solved by enabling all verbs for WebDav (yes, WebDav - don't ask me why I just followed instructions on a blog post :-D).

Do this:

• Open IIS manager, go to your application's Handler Mapping.
• Double click the WebDav handler
• Click "Request Restriction"
• On the "Verbs" tab, select "All verbs".

Again, no idea why WebApi uses WebDav, but this solved problems with POST and DELETE that wouldn't work in spite of a correct CORS implementation.
