Day 1: Publish Schemas as a Web Service
Suppose you want create a web service with Biztalk all you need to do is define your Request and Response in a XML schema file and use the Web Services Publishing Wizard to create the web service. Not a single line of coding. Pretty cool huh, wait until you try it.
Why?
I don't know yet. But I got to, it seems doing this will add more value to your web services as Biztalk can do some enterprisey stuff. Will update this once I know better.
How?
Do these in the exact order

Fix them. All done good. You are not done yet. Now send a request to your web service and hope that it doesn't time out and returns a response. As for me, I keep getting a timeout error. Yes, I did try setting a higher timeout (20 mins) yet didn't make any difference.
