Creating a new WebApp project template through the extension fails to build. This is caused by incorrect icon type in the MainLayout.razor file.

To make sure the app is correctly built, the Icon type should be FontIcon.

<TelerikButton Icon="@FontIcon.Menu"
               FillMode="@ThemeConstants.Button.FillMode.Clear"
               OnClick="@( () => DrawerExpanded = !DrawerExpanded )" />
