Thank you for contacting us.
The Telerik menu is context sensitive and the commands depend on the projects loaded in your Visual Studio. If you start from the scratch (no project loaded in Visual Studio) you see only Create New Telerik Project command under UI for WPF. Use this command to create and configure a basic Telerik WPF Application. Such an application can further be configured or upgraded (in case new a version of our controls is available) using the Telerik menu. Otherwise, if you start with an existing WPF project that is not Telerik WPF Application you first have to convert it (use Convert to Telerik WPF Application command).
Please let us know if that helps.
Check out Telerik Analytics, the service which allows developers to discover app usage patterns, analyze user data, log exceptions, solve problems and profile application performance at run time. Watch the videos
