I have been using Unity (docs found here) for a little while now and one thing that annoyed me was having to explicitly declare every mapping from my an interface to a class, especially when I only had one Interface to one Class!
This was leading to a couple of issues: the first being that (especially with a large project) you ended up with a massive unity config file; the second is that you had to remember to wire up every new Interface and Class you created and if you didn’t you got exceptions, which is annoying and tedious.
I have found a solution to this issue by making use of Unity’s Auto Resolver. The configuration of this is shown below.
container.RegisterTypes( AllClasses.FromLoadedAssemblies(), WithMappings.FromMatchingInterface, WithName.Default, WithLifetime.Transient);
It maps everything where the interface matches the name and there is only one class per interface, all for you!
only suggest you use this for new projects or carefully with existing projects, this is because if you delete all of your current mappings you would need to check the resolution of every object in your project, to be positive that it works and that you do not get any missing mappings.
