Generally Available: Support for .NET 8 using the in-process model in Azure Functions

The in-process model for .NET applications on Azure Functions now supports .NET 8. Initial support covers Windows apps outside of App Service Environment deployments. Please see this GitHub thread for the latest status regarding Linux and Apps Service Environment deployments.

To date, apps using the in-process model in the Azure Functions V4 runtime have run on .NET 6, and support for .NET 6 ends on 12 November 2024. These apps can upgrade to .NET 8 either by migrating to .NET 8 on the isolated worker model or by leveraging this new in-process option for .NET 8.

As a reminder, support for the in-process model for .NET on Azure Functions ends 10 November 2026. Function authors that choose this in-process model option for .NET 8 should still begin planning a migration to the isolated worker model prior to that date.
