Azure Functions on .net core 3.0

Question

Now that .Net Core 3.0 has released what's the story for Azure Functions on core3?

When I try to flip a project to <TargetFramework>netcoreapp3.0</TargetFramework> it still reports as running on 2.2.

If I try to access an api that's 3.0 only it explodes, which makes sense since it seems to be forcing it's runtime despite the project settings.

The issue was updated : .NET Core 3 is available in preview, and should be available in 2020 – Dominance

I looked at that post for instructions to preview, but after updating templates according to the instructions, the "Azure Functions v3 Preview" isn't available in the dropdown. I was going to leave a comment on the blog asking about it, but the amount of information they ask before you can comment are too much. – Inconsolable

@PaulDempsey did you set the environment variable (AzureFunctionsHiddenTagsVisible)? And restart VS? It worked for me.. – Haigh

same issue for me – Goral

Answer 2

Yesterday (09.12.2019), Microsoft announced the Azure Functions 3.0 go-live release which supports .NET Core 3.1 which has a Long Term Support (LTS).

On March 3, 2020, the Support for .NET Core 3.0 ends - so for anyone reading this, you should use .NET Core 3.1 and Azure Functions 3.0
