Blazor styling changed from ui- to rz-

Hi. I upgraded to the latest nuget release and the grid styling I was using got ignored. I see that the classes went from prefix from ui- to rz-.

Am I doing something wrong? How to get the old classes back?

Thanks.

You can go back to the old version if you want old classes.

This happened quite a while ago and is documented here: Migrating from Radzen.Blazor 2.x to 3.x
