Creating a Telerik project for the "Standard" option is broken (VB.NET and C#):

1. The project fails building due to this error:

2. The rendered hamburger menu does not appear properly:

 

I recently updated my Telerik extensions in VS2019 and the MVC extension (v2022.1.429.1) is causing Visual Studio to hang when I open a solution that is based on KendoUI for MVC.  When I disable the extension the solution opens normally and no hang is encountered, I am able to navigate the projects in the solution and perform all required actions.

I just upgraded to the latest Telerik version.  First of all, congratulations on a job well done on the MVC Project Upgrade Wizard!  With version 2017.3.1026 it was unreliable, took hours to run, and generally locked up Visual Studio; the new version runs cleanly and quickly.

One comment:  The popup dialogs for the Upgrade Wizard do not adapt to different screen resolutions.  I see this where my primary display is high resolution (3840 x 2160) and the secondary is lower res (1920 x 1080).  The effect is that the popup dialogs are cropped if Visual Studio is running on the secondary display:  the message ("file xxx exists; do you want to overwrite?") appears, but the Yes/No buttons and "apply to all files" checkbox do not.  The only actionable option is to kill the dialog, at which point the next one pops up.  The only way I found to stop the Wizard is to kill Visual Studio through the Task Manager. 

The Wizard works perfectly on the primary high-res display.
