## Description

The control examples are not loading in the Telerik UI for WPF Controls Demo application. The busy indicator stays at 0.

This often happens when you have an older installation of the [Telerik UI for WPF Controls Demo](https://demos.telerik.com/wpf/) application and you install the latest one. It is related to cache in the [ClickOnce](https://www.telerik.com/products/wpf/documentation/knowledge-base/kb-sdk-samples-browser-cannot-be-installed-or-run) files of the application located in C:\Users\\\<your_user>\AppData\Local\Apps\2.0.
