Are you wondering what I have been up to? You should visit urda.com/projects and take a look.
Being able to drop certain chunks of code from one piece of software to another piece of unrelated software is a powerful thing. Not only does this save time, but it will also allow you to build a small library of tools you find useful in all your applications. Interfaces in C# is just one of many ways to build more modular objects that have similar behavior.
When you create a basic WCF service hosted through IIS, you are greeted with a generic page informing you that “You Have Created a Service”. This is useful since it provides to the developer two critical pieces of information. First it lets you know that the service is up and running, second it provides basic code stubs to query the service with. While this may be fine for development, you might not want to display this page in production. Disabling it is not intuitive, but with some searching through the MSDN documentation I have found the preferred way of changing this page.
