You can now build your serverless applications with .NET 7 runtime when running in the isolated process mode in Azure Functions v4. Apps. This was built following the same patterns as previous .NET versions in an isolated worker model in Functions.
This feature is available for preview in all Windows-based plans, Linux dedicated, and premium plans. Linux consumption plan will be added at a later date.
Please share your feedback and use cases on Azure Functions .NET language worker GitHub repository.
