What is the maximum size (string length) of an AppSetting Key and its Value? All I have found is the maximum permitted size of an ASP.NET Web.Config file which is 250 KB by design.

  • Does this apply to "the total" of all Azure WebSite AppSetting configurations which I set in the Portal?

  • And what are the permitted Key and Value (string) lengths in both web.config and portal?

Thanks!

There does not appear to be a max key / value size.

Max key/value length in 'application configuration' files

However, you are correct in the max file size for web.config by default being 250kb.
