+## Description
+
+I cannot create a new project through the template wizard of the Telerik UI for ASP.NET Core Productivity Tools extension for Visual Studio Code, or the extension does not work as expected. How can I solve the issue?
+
+## Solution
+
+If the extension does not work right (missing pages, not starting, and more), follow the next steps to clean up the cache files and get it working again:
+
+1. Uninstall the extension from VS Code.
+2. Go to the extensions templates cache folder and delete the `CoreT` folder (this is where the cache for the Telerik extensions is stored):
+    * on Windows, open `%localappdata%`
+    * on Mac, open `/Users/[user_name]/.local/share/`
+3. [Install](https://marketplace.visualstudio.com/items?itemName=TelerikInc.aspnetcoretemplatewizard) the extension again.
+
+If you see `Response status code does not indicate success: 401 (Logon failed.).`, then the `Nuget.Config` file in `%APPDATA%\NuGet` may contain invalid credentials or keys. For more information, refer to the [Installing with NuGet]({% slug nuget_install_aspnetmvc6_aspnetmvc %}#setup-with-nuget-cli) or [NuGet Setup with CLI]({% slug gettingstartedcli_aspnetmvc6_aspnetmvc %}#integrating-ui-for-aspnet-core) articles.
