How to restart REST Services?

I want to restart the REST service since even after adding a new service or services I don't see any change in the help page at all and afterward all the services don't work... Is their any solution to this... worst case 开发者_运维技巧scenario I have to create a new project all over again...

By the way Im using C# .NET 4.0

I dont actually host the service yet. I just run the service then use a client windows application and run it.

my config is just the basic config.. Actually when i create a new project and copy these codes it works again. So i think this might be an issue with Microsoft WCF REST itself

and sometimes when I add a new service may it be any of the crud functionality they also don't show in the help and have a not found exception.

Thank you :)
