Circular References in Visual Studio

[Keith F.]

Visual Studio doesn't allow circular references between projects. I have a
situation where I need to allow 2 projects to reference each other.
Is there any way to make Visual Studio allow this?

I realize the best way is to restructure the solution so the circular
reference isn't necessary, which I intend to do. But at the moment, I'm
looking for a quicker work-around if there is one.
Thanks....

Nope. Look at the problem a little closer and you'll see why.

Say you have projects A and B.

A needs something from B and B needs something from A.
A is compiled first, so it goes and grabs the contents of B as it is linked.
In this process it checks B for any dependencies and finds A. As a result
it grabs the contents of A and looks for dependencies and finds B... See
where this is headed?

Same reason if you have two classes C and D. And C is a child of D, that is
C inherits D. D cannot also inherit C. This is sort of the same idea.

Inheritance / references are simply ways of reusing code. What I would
suggest is putting these reused controls in a separate 'class library' then
have both A and B reference the new library L.

Do not reference project.

Reference compiled DLL.

It will be a quick workauround.

George has an interesting solution which will work, but "working" is a
relative term here. You could end up consuming resources if you truly run
circles.

One other possibility, which adds a bit of weight, but can add a safety
measure, is creating a passthrough class with the method signatures
necessary from the other project. Realize that true circular references will
still be dangerous, even with a passthrough class, if you do not add a
safety net if it starts running in circles.
