when i deploy to azure using a publishing profile I get _content/Radzen.Blazor/Radzen.Blazor.js not found. I assume this is true for the css as well because the controls look like they are missing formatting. I don't know if _content is some magical place, but I assume it's part of the package contents and made available at runtime?
Please make sure the app is published in Release - this is what we do in our Docker:
when publishing https://blazor.radzen.com/
More info about the _content directory and static web assets is available in the official Microsoft documentation.
