Question

how do i register and resolve a generic object/interface in Unity? I'm trying to stay away from the config file.

I'm looking for something like

IEnterpriseClient<IInterface1> to resolve to EnterpriseClient<IInterface1>

The class signature is

class EnterpriseClient<T> : IEnterpriseClient<T> where T : class

Thanks!

Answer 1

It's pretty much exactly what you'd think:

container.RegisterType<IEnterpriseClient<IInterface1>, EnterpriseClient<IInterface1>>( ... );

That's if you only want that particular closed generic registered. For the open generic (not just IInterface1), you can do:

container.RegisterType(typeof(IEnterpriseClient<>), typeof(EnterpriseClient<>), ... );

You mentioned you'd tried this - what's not working?

Look at this question for XML configuration: Unity 2.0 registering generic types via XML

and http://davidhayden.com/blog/dave/archive/2008/03/25/UnityDependencyInjectionOpenGenericTypes.aspx for code configuration.
