So today I learn about WebServiceHost. Just a normal class but it does a lot for me today. This host the web service within you Desktop/Windows Service application. i.e. you don’t need to install any Web server or other stuff, just create a Service Contract Class and use WebServiceHost to host it within your application. 

I need this as part of my project, because I have to pass some server information to my application. I initially create a Seperete web application for this, but why maintain another application and increase setup time when I can host it within. I need it for just one particular value to be pass in JSON format to my client side. However one thing I must tell here is that the Host server application must be running as Administrative privilege or the service won’t start. For Windows Service run application as “LocalSystem” rather than default LocalService to keep it working.

It solve lot of problem and architectural issue I had in my project.
