Multiple projects sharing same code without circular reference

Question

I have a C# and F# project. Both are supposed to be a service layer code. But sometimes, code from both project need to access code in the other project.

Can each project reference the other without any problems?

Answer 1

You can't have circular assembly references. This will require refactoring the parts used by both assemblies into a third assembly, which can then be referenced from both.

Answer 2

You need to create 3d project where you must add references from both and then you can use methods and objects from C# and F# projects together.

But usually you don't need such cross-reference. That must be an architecture problem.
