WCF - Deployment and configurational issues

Today when I hosted WCF service in IIS 7.0. I got an error like

HTTP Error 404.3 - Not Found Description: The page you are requesting cannot be served because of the Multipurpose Internet Mail Extensions (MIME) map policy that is configured on the Web server. The page you requested has a file name extension that is not recognized, and is not allowed.

I explored and found solution.

Solution:
What is intuitive here is that .svc extension is not recognized i.e. Http handler of .svc is not defined :) So the solution I found was that:
In the control panel > add remove programs > windows on off programs, select WCF HTTP Activation and WCF Non-HTTP Activation as in the picture:

Windows will take few minutes to update and after that your WCF Service will run smoothly on Vista and IIS7.



Also, I got some other issues while deploying WCF service on IIS7 on Vista OS, after installing below items under IIS7, things were fixed.

The Secret of Luck: Why Some People Have All the Luck

Why do some people have all the luck while others are perpetually unlucky? Professor Richard Wiseman of the University of Hertfordshire was determined to get to the scientific bottom of the phenomenon of luck, and what he discovered may surprise you:

I placed advertisements in national newspapers asking for people who felt consistently lucky or unlucky to contact me.

Hundreds of extraordinary men and women volunteered for my research and over the years, have been interviewed by me. I have monitored their lives and had them take part in experiments. The results reveal that although these people have almost no insight into the causes of their luck, their thoughts and behaviour are responsible for much of their good and bad fortune. Take the case of seemingly chance opportunities. Lucky people consistently encounter such opportunities, whereas unlucky people do not.

I carried out a simple experiment to discover whether this was due to differences in their ability to spot such opportunities. I gave both lucky and unlucky people a newspaper, and asked them to look through it and tell me how many photographs were inside. I had secretly placed a large message halfway through the newspaper saying: ‘Tell the experimenter you have seen this and win $50′.

This message took up half of the page and was written in type that was more than two inches high. It was staring everyone straight in the face, but the unlucky people tended to miss it and the lucky people tended to spot it.

Unlucky people are generally more tense than lucky people, and this anxiety disrupts their ability to notice the unexpected.
