When I try to create a new Azure Functions app in Visual Studio 2026 Insider edition, I don't get .NET 10 as an option -- see below:
I do have .NET 10 as an option for other project types such as .NET MAUI, ASP.NET Core, etc. Also when I check installed versions of .NET on my computer using dotnet --list-sdks, I do see .NET 10.0.100 rc2-25502-107 listed.
Any idea why .NET 10 isn't available for a new Azure Functions app?
As of the time of this posting, 2025-11-01 (in the neighborhood of 10:38, UTC), .NET 10 was still in RC 2 status, not having been released to the world as of yet. I expect that is why you don't see it available in the drop-down yet.
I would wait until Monday, 2025-11-03, for them to release the software and generally "kick the tires" and make sure it works before introducing into other systems like Azure Functions.
In the meantime, you can attempt to create a new Azure Functions app via the CLI.
You can get the latest Azure Functions tools and that will solve your issue in VS 2026 Insiders.
Use Visual Studio 2026 Insider Edition.
Go to Tools > Options > Projects and Solutions > Azure Functions and click Check for updates.
Ensure you have Azure Functions tools version 4.114.0 or later.
