Castle Windsor: Constructor resolution order

Question

Hi guys

Just wondering how Castle Windsor determines which constructor to resolve when there are multiple constructors present.

Cheers Anthony

Answer 1

All available constructors are modeled as candidates and basically a contest is run among them.

Each parameter in a constructor represents a dependency that can be either satisfied or not. For each constructor candidate, all dependencies are analyzed.

If a dependency can be satisfied, that's two points for the candidate. If it can't be satisfied, two points are subtracted from the candidate.

The constructor candidate with the most points wins and is chosen to instantiate the component.

The code for this algorithm is here.
