Where is this going at, any news on possible GA date?

Adding @jviau and @lilyjma.

The current plan is to release another preview before the end of the year, followed by GA early next year. It's taking a bit longer than originally planned because we decided to do some significant refactoring to align this SDK with the patterns used in the broader .NET ecosystem.

We were expecting this to be ready before the December 3 deadline. It means our Azure Functions (currently on .NET Core 3.1) won't have any security patches after that date. The only option we have would be to first migrate them on Azure Functions 4 using .NET 6 and the in-Process model, but it means that should plan a second migration when .NET 7 isolated is released.

We don't mind waiting until next year, but Microsoft should post pone the deadline so that we can avoid two migrations.

It looks like we won't have durable entity support in the first release. This is a real shame, because for us it means we cannot move forward yet. Also NET 7 upgrade is failing with older in-proc functions, so this is becoming a real bottleneck.

any news on that ? we're also blocked to migrate to .NET 7. any timeline would be good !!! currently there is an RC but with a note note to use in production...

So for time being there ain't gonna be rush for NET support except for LTS versions: https://techcommunity.microsoft.com/t5/apps-on-azure-blog/net-on-azure-functions-roadmap-update/ba-p/3619066
