Documentations are still missing on some features,

Akka.NET 1.5

• [x] [Akka.NET] Dual targetting: https://github.com/akkadotnet/akka.net/pull/5926

Akka.Management

These needs to be mirrored to the main Akka documentation:

• [ ] Akka.Hosting support: https://github.com/akkadotnet/Akka.Management/pull/756
• Deployment scenarios should go to this documentation section: https://getakka.net/articles/deployment/index.html
  • [ ] Azure App Services deployment: https://github.com/petabridge/azure-app-service-akkadotnet
  • [ ] Azure Container Apps deployment: https://github.com/petabridge/azure-container-app-akkadotnet

Akka.Hosting

Pretty much everything, will need to update all documentation and offer an alternate sample that uses Akka.Hosting instead

• [ ] Break this down into managable chunks

NOTE: Please add more links below if you find anything else that needs documentation.
