.NET 10

What is the deal with Ubuntu and this version of .NET?

Every since they got rid of the Microsoft packages feed, it's just been a complete mess.

Ubuntu's own documentation states:

> .NET 10 will be available in the Ubuntu archive for Ubuntu 24.04+ and included in main upon its official release

But it isn't available?

Microsoft's Ubuntu image seems to be ready. I guess I could see a reason to use regular Ubuntu 24 and then install dotnet manually, but these images have served us well.

docker pull mcr.microsoft.com/dotnet/sdk:10.0 - Refers to Ubuntu 24.04 "Noble Numbat"

docker pull mcr.microsoft.com/dotnet/sdk:10.0-noble - Refers to Ubuntu 24.04 "Noble Numbat"

See the docs[1] where it mentions that 10 is supported, but not available in the built-in Ubuntu feed. It however is/should become available in the backports feed.

To make matters even more interesting the GitHub / Azure DevOps CI agent image Ubuntu 24.04 doesn't provide .NET 9, whereas 22.04 does[2]. .NET 10 appears to become available in both though[3].
