I have not experienced VS2022 setting a file build action to None by default.

I found this StackOverflow item by Googling but it is old and I never like messing around with the registry. https://stackoverflow.com/questions/747844/default-build-action-for-a-filetype

It might be worth you experimenting with creating new projects and adding various file types and immediately seeing what the settings are in Properties window and comparing that to the .csproj file.

For example, adding a C# class file named SecurityHeadersMiddleware.cs to an ASP.NET Core project should default its Build Action to C# compiler and no entry for it should be made in the .csproj file. But if the Build Action for that file is changed to None then the following entries are added to the .csproj file:

  <ItemGroup>
    <Compile Remove="SecurityHeadersMiddleware.cs" />
  </ItemGroup>

  <ItemGroup>
    <None Include="SecurityHeadersMiddleware.cs" />
  </ItemGroup>

I will think about how to add a section to the next edition about build actions, especially in ASP.NET Core projects, since it'd be a useful topic for all readers to be aware of.

OK, we might as well write this one off. I'll try to keep an eye on the properties when I add a new file to a project.
