Accessing an entity through a dll chain

Hi, 

Here is my scenario: I have three .dll class libraries, LibraryA, LibraryB, & Library C.
Library A references B and  B references to C, like so: LibraryA -> LibraryB-->LibraryC   .
In these libraries I have my classes, enums, structs, etc.
 
Sometimes I need an enum from library A and use it in library C. 
This creates a circular dependency, so  I cannot access this enum from library C.
How would I solve this problem?

Should I create a new common library, say LibraryD, which includes all of the shared items of Library A-B-C?

Thanks and best regards,

Hi,

Yes. Create a new class library project and keep all your common functions inside this library and referenced it wherever required.

Hi
Could you please explain your problem little more clear.
From your statement "Sometimes I need an enum from library A and use it in library C. "

I guess you mean libraryA.Enum is required by LibraryC?

If my guess is correct , considering the Chain you have put here, there may be a Cyclic Reference only if Library A tries to use an Enum defined in LIbrary C. In your case it should not be a problem.

Ideally if you want to expose an Enum defined in Library A to Library C you should have a public Property in Library A, which could be used by C.


Library A...

MyEnum _myEnum=MyEnum.DefaultValue;
public MyEnum MyEnumerator
{
 get{return _myEnum;}
}

Library A internally - at any instance may update _myEnum private variable so that Library C can only use A's Enum and not update it.

Hi 

Your guess is right, you should create a new common library which will have common code which can be used in any other library.
