Output 类型为 Class 库的项目无法直接启动，Azure Z86408593C24AF77FDD90DF93 中的 Z86408593C24AF77FDD90DF93

Question

I have recently updated my VS to 2022. My project is Azure Function App.

But when I click on debug item, I am getting the following error.

A project with an Output Type of Class Library cannot be started directly 
        
In order to debug this project, add an executable project to this solution which 
references the library project. Set the executable project as the startup project.

Usually, I prompt screen would appear with my Function app running.

What could be the issue?

Answer 1

Strange, because azure function work in VS2022 without any issue for me, which version of target framework is used in your function?

Answer 2

Try cleaning and rebuilding your project. Also, if you have multiple projects try setting up a startup project and then compile the same.

Here are few workarounds that you can try

1. Try cleaning and rebuilding your solution.

2. If you have multiple projects try setting up a startup project and then compile the same.

   

3. If the above doesn't work try adding a new project to your solution and set Output Type of either Console Application or Windows Application. For this you can navigate to your properties by right clicking on your project

I got it working. Seems that during installation Azure Development was not selected.
