Diving into Licensing Class of Windows Phone 7

If you are building applications for Windows Phone 7 Marketplace you will love this.

It has never been easier to make a trial version of your application. A class provided my Microsoft makes it easier for us developers to build trial versions of our application in a very easy way.

On MSDN, Microsoft has documented a simple class which when calling it’s method IsTrial() the return value is a boolean expression which returns true if it is operating on Trial Mode and false if it is the full version.

The implementation should be like this.

Microsoft.Phone.License.LicenseInfo MyLicenseInfo = new Microsoft.Phone.License.LicenseInfo();
if (MyLicenseInfo.IsTrial())
{
// Do the limitation here
}

It was very difficult to create graphically nice animations that utilizes the GPU and ensures smooth animations so we found our selves trying to learn OpenGL/ES or any other SDKs like Fluid or SilverMoon which all are complicated enough and can waste a lot of time learning them. (continue reading…)
