Hide namespace in 3rd dependent project

I Have 3 projects in same solution, each dependent from the one before (DB <- Provider <- WinUI). In DB I defined a Behaviour class that will be used in Providers with a mapper Behavioud class, this last used by WinUI project. (WinUI doesn't depend directly from DB).

Is there a way to hide the clases from DB inside WinUI? this project only should use the provider clases.

Solution

  • First, mark the Behaviour class in the DB project as internal.

    Second, add

    • for a project that contains an AssemblyInfo.cs file 
      [assembly: InternalsVisibleTo("Providers")]
    • for .Net 5+, in the csproj file (more info) 
      <ItemGroup>
  <InternalsVisibleTo Include="Providers" />
</ItemGroup>

    internal prevents the class from being visible in other assemblies. The assembly attribute allows sharing internal classes with the assemblies you name.
