The license type of the current license. In developer mode, this function returns LicenseType.Developer. Otherwise, it can return LicenseType.NamedUser if the app was licensed by logging in to a portal and acquiring a LicenseInfo, or LicenseType.LicenseKey if the app was licensed from a license string. The license type can change while an app runs. For instance, the app may start running licensed with a Lite license key (LicenseType.LicenseKey) and later become licensed from LicenseInfo (LicenseType.NamedUser).
