.Net Core Project Reference Inheritance [duplicate]

Question

I noticed when using .net core 2.2 if you add a project reference to another project those project references are available to other projects that reference the original project.

For example:

If you have a 3 projects, let's say UI, Services, and DAL. If you have a reference to Services from UI and Services has a reference to DAL. With that set up, you will notice you will be able to add a using statement and gain access to classes in the DAL project from the IU project. Whats the reasoning behind this and can it be disabled?

UI
-- project references
---- Services

Services
-- project references
---- DAL

Answer 1

I took @Kirk Larkin comment and made it work for me, however I had to use "ExcludeAssets" instead:

Imagine something like this:

-- GUI

---- Business layer dll

------ Data access layer dll

Inside the Business layer dll project file (csproj):

<ProjectReference Include="..\..\DALProject\DALProject\DALProject.csproj">
  <ExcludeAssets>compile</ExcludeAssets>
</ProjectReference>

With this, I can no longer reference DALProject methods from my GUI layer where it's not directly referenced. This method also includes all the supporting DLL's for runtime use.

Hope this helps.
