Error publishing .NET core app in Azure Devops YAML Build

Short story, I’ve created a simple YAML build for a .NET core project where one of the task will publish a simple .NET core console application. After running the build I’ve a strange error in the output

No web project was found in the repository. Web projects are identified by presence of either a web.config file or wwwroot folder in the directory.

This is extremely strange, because the project is not a web project, it is a standard console application written for .NET core 2.2 so I do not understand why it is searching a web.config file.

Then I decided to create a standard non YAML build, and when I dropped the task on the build I immediately understood the problem. This happens because dotnet core task with command publish is assuming by default that a web application is going to be published.

Figure 1: Default value for the dotnet publish command is to publish Web Project

Since I’ve no Web Project to publish I immediately change  my YAML definition to explicitly set to False the publishWebProjects property.

  - task: DotNetCoreCLI@2
    displayName: .NET Core Publish
    inputs:
      command: publish
      projects: '$(serviceProject)'
      arguments: '--output $(Build.ArtifactStagingDirectory)'
      configuration: $(BuildConfiguration)
      workingDirectory: $(serviceProjectDir)
      publishWebProjects: False
      zipAfterPublish: true

And the build was fixed.
