I was able to reproduce the error.

When I convert a project with no authentication type, it works. 

When I convert a project with Microsoft Identity Platform, I see the error. 

Steps To Reproduce

1. Install a Telerik VS extension in Visual Studio 2019/2022 on a machine with high DPI scaling (more than 150%)
2. Try to create a new Telerik application

Expected result:

The Create New Project wizard (or any other used Telerik wizard) is shown and usable as expected.

Actual result:

The Create New Project wizard is hidden or inaccessible and the project creation is blocked.

A Blazor WebAssembly app crashes at runtime due to a missing DLL for the Shared project. This happens after I makes any change to the app, e.g. in Index.razor in the Client project. The Shared project remains unchanged.

The exact exception is:

FileNotFoundException: Could not load file or assembly [AppName].Shared.dll

If I clean and rebuild the solution, it runs again, until I make another change.

If I uninstall the Telerik Blazor Visual Studio extension, the error goes away. Alternatively, another possible workaround is to reduce the number of parallel builds in Visual Studio to 1.

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.

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.
