@Rick-Anderson @scottaddie Every preview release won't be preloaded to Azure App Service going forward. We have two options to address this issue next week:

• Remove the note completely.
• Leave the note and update it.
  • Remove info specific to this pre-release.
  • Link our content for working with previews: https://docs.microsoft.com/aspnet/core/host-and-deploy/azure-apps#deploy-aspnet-core-preview-release-to-azure-app-service

Which way would you like to go?

To note ... or not to note ... that is the question. 😄

@guardrex I do think it's important to note that not every preview release will be made available. I'm all for making the note as generic as possible.

Sounds good. I'll do that.
