It appears there is a packaging problem with version 2026.3.811 of Telerik.UI.for.AspNet.Mvc5. It lists the package dependency for Telerik.SvgIcons and Telerik.FontIcons at version 4.9.2 in the nuspec file. But compiling a project using Telerik.UI.for.AspNet.Mvc5 results in a package version conflict on these two because the actual Kendo.MVC.dll is dependent on version 4.11.0 (verified with dotPeek) of those packages.
