I've upgrade an existing project from core 3.1 to core 8. I'd like to use QuickGrid to replace an existing top level of a multiple nest set of HTML tables. Everything seems to work except none of the formatting from the Microsoft.AspNetCore.Components.QuickGrid.bundle.scp.css is showing up. Example the Paginator goes down the page starting with Item Count, then 2 tiny boxes instead of the left arrows, then page of, and finally 2 more tiny boxes instead of the right arrows. Reviewing the HTML in the browser it is referencing BootStrap's _Print.scss instead of the QuickGrid css. Yet, it all works. The using statements are on both the razor and cs files of the form for Quick Grid component, and I just installed the latest QuickGrid from NuGet for Core 8; so not sure what I might be missing.
I did get it to display properly by downloading and including the file Microsoft.AspNetCore.Components.QuickGrid.bundle.scp.css as part of the applications css files, and adding the link in the head tag of the _Host file; however, I'd prefer to pull directly from package especially for future upgrades.
Control+F5 did the trick for me...
