Exception adding new razor page

Radzen Blazor Studio
1

I download v1.0.0 preview.7

Created a default Blazor Server App in VS2022 (adding Radzen component nuget - i have pro licence) then opened the sln in Blazor Studio and then added a razor page:

Encountered the following exception:

Cannot provide a value for property 'DialogService' on type 'BlazorServer01.Pages.PriceStatusGrid'.

Select an existing component or drag and drop a new one from the Toolbox.

Please send us your app to info@radzen.com so we can troubleshoot.

The application does not have the required services registered hence the exception (you would get the same exception if you run the application).

  1. Either register the DialogService, TooltipService etc. or
  2. Delete the code which injects them from the page:
        [Inject]
        protected DialogService DialogService { get; set; }

        [Inject]
        protected TooltipService TooltipService { get; set; }

        [Inject]
        protected ContextMenuService ContextMenuService { get; set; }

        [Inject]
        protected NotificationService NotificationService { get; set; }
    }

We will think how to approach this issue somehow - either by asking the user whether to inject those services (a checkbox in the NewPage dialog) or something similar.
