Description

Feature summary :

Microdosft released .NET 10 on 11 November 2025. [https://dotnet.microsoft.com/en-us/platform/support/policy/dotnet-core] With .NET 10 now available, the clock is ticking on previous versions. Both .NET 8 and .NET 9 will reach End of Support on 10 November 2026. In other words, now is a good time to start planning a migration. Heroku has support for .NET 10. [https://www.heroku.com/blog/support-for-dotnet-10-lts-what-developers-need-know/]

Can we get the toolforge to handle .NET 10?

Benefits : This will ensure .NET availability until November 2028

I couldn't get heroku:24 to work, but I was able to build .NET 10 with

pack build $CONTAINER --buildpack paketo-buildpacks/dotnet-core --builder docker.io/paketobuildpacks/ubuntu-noble-builder-buildpackless  --env BP_DOTNET_PROJECT_PATH=./$TARGET

where $CONTAINER is the name of my container and $TARGET the directory it is in
