Hide namespace in 3rd dependent project

Question

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.

Just a small point, you can't really prevent _namespaces_ from being shared, and it shouldn't really matter anyways. The only thing you can restrict is if _types_ are accessible. — gunr2171, Apr 30 '22 at 01:32

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.
