Hi,

I am getting the following error message when trying to upgrade from 3.6.1 to 3.7.0. I tried multiple times without success.

===========================================================

An error occurred while running the wizard.

Error executing custom action Telerik.Blazor.VSX.Actions.MultiProjectUpdateMasterPageAction: System.InvalidOperationException: Sequence contains no matching element
   at System.Linq.Enumerable.First[TSource](IEnumerable`1 source, Func`2 predicate)
   at Telerik.Blazor.VSX.Actions.AdvancedUpdateMasterPageAction.RetrieveMasterPageSettingsUpgradeInfo(IPropertyDataDictionary arguments, IProjectWrap project)
   at Telerik.Blazor.VSX.Actions.UpdateMasterPageAction.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments, IProjectWrap projectWrap)
   at Telerik.VSX.Actions.MultiProjectActionBase`1.Execute(WizardContext wizardContext, IPropertyDataDictionary arguments)
   at Telerik.VSX.WizardEngine.ActionManager.ExecActions()

===========================================================

Thank you

After installing Telerik UI (for WPF and BLAZOR) - the Intellisense / Autocompleter stopped working in Visual Studio 2022 17.4.2

https://www.youtube.com/watch?v=6Fn5C726h4U

Enter and Tab no longer inserts the snippet. 

After uninstalling Telerik UI from Windows, the Intellisense / AutoCompleter started working again !

The Upgrade (Project) Wizard crashes on the screen where it askes whether to use a backup.

The "Show me more" link gives this:

The wizard encountered an error while trying to handle user event.

I cannot continue to the next page. I want to upgrade the existing 3.5 to 3.6

Installation of trial Blazor UI broke Visual Studio 2022 extensions. Cannot create Telerik Blazor project. Cannot open VS Blazor projects.

Installation gives an error dialog

 

These settings creates additional controls and are really helpful in further development. It would be great if same(or better as always) options are added in telerik blazor project templates as well would be a great addition.
