Visual Studio 2022 and .net update issues for Azure Function App

Question

I have been using Visual Studio 2019 for my Azure Function App. I recently updated to version 2022, I then uninstalled 2019.

I am getting the following errors now:

Do I need to install version 3.0.1 to make it compatible with Azure Function Apps?

Answer 1

Yes you can resolve this by installing .NET Core 3.1 SDK,

When targeting Azure Functions 3.0, by default, the .NET Core 3.1 SDK is required on the machine building the project.
