Trial License Limitations
The following topic will explain you the main differences between the licenses available for the Telerik UI for WPF and the limitations of the Trial License.
Currently there are two types of licenses used for UI for WPF:
Developer License
Trial License
Developer License
Developer licenses come with modified DLLs, which work without license keys. If you have a Developer license for one or more of the Telerik components, you only need to ensure that you are using the developer build when downloading the control(s). These builds have the Dev abbreviation in their file names.
If your application is displaying a license key error, this means that you are using a trial version of the product. Log in to your telerik.com account and download the developer build. To update your project, please take a look at the Upgrading Trial to Developer Licensearticle. To get a license key, see the Installing License Key article.
Trial License
The free trial licenses of all Telerik products are fully functional and will work for an unlimited time but with a trial message displayed in a popup dialog and a watermark overlay banner that is displayed until the dialog is closed.
The trial message states that the application uses a trial version of Telerik UI for WPF and prompts you to purchase a developer license.
