Blazor File Downloads Documentation

[berets76]

Hi, looking around for the answer to the question "how to download a file with blazor server", several approaches are suggested, but it's not clear what the best solution is.

I found samples using controller, razor page, javascript interop, and some others hacks.

Is there a best practice regarding this topic ?

In the specific case, if I've a PDF file (but it could be anything else) content as byte[], what is the officially recommended method to generate a download in the browser ?

Thanks

Thanks for pointing out that repo, I've left a comment regarding leveraging .NET 6 via native byte[] & streaming interop which should provide significant performance benefits for that project: arivera12/BlazorDownloadFile#28 (comment)
