As Windows Phone is gaining momentum, more and more startups and students are developing apps. However it is often the case that newbies don't make use of some very useful classes natively present in Windows Phone namely Launchers & Choosers.
While an app would still be complete, Launchers make it really simpler to allow app users to perform some basic tasks without much effort from developers. For example the three line of code below allows your app to update or share status on social media engines (Outlook, Facebook, Twitter, LinkedIn, etc.) that are integrated into Windows Phone.
ShareStatusTask statusTask = new ShareStatusTask();
statusTask.Status = "Hello World";
