Question

I have two projects in my solution and in each of them I have a CS file containing a public class. Since both classes are in the same namespace, I was expecting them to be able to see each other. That is not the case. See the setup below.

Project Woof1, file File.CS

namespace MyNameSpace
{
  public class Foo
  {
    // Doesn't compile
    Faa f;
  }
}

Project Woof2, file File.CS

namespace MyNameSpace
{
  public class Faa
  {
    // Doesn't compile
    Foo f;
  }
}

NB, both classes are stored in files with the same name but in different directories (i.e. not the same file).

1. Why can’t I compile it?
2. What can I do about it (except moving the classes to the same project).

(I only found this discussion on the subject but in the end it wasn’t really my issue.)

Answer 1

1. Make sure the references are set up as supposed to. Each project needs to refer to the other.
2. Make sure to set public qualifier on all the classes in the projects.
3. Make sure to set public qualifier on all the enumerations in the projects.

Also, preferably, you might want to move your enums and other auxiliary definitions to a common project and store them there.
