Thanks for the suggestion, Mauricio. That would work, but I'm trying to go
with a more automatic way of accomplishing this. Krzysztof's comment is
spot on, and sent me down the path of looking at lifestyle managers and
activators, but it looks like I'm going to need to write some custom
extension code to accomplish this.
To be specific, this is what I want to accomplish:
public class EsentRepository<TKey, TValue> : IRepository<TKey, TValue> {
public EsentRepository(string directory) { }
}
public class A {
public A() {
_repo = new EsentRepository(typeof(A).Name); // or any string directory
that is unique to instances of A
}
}
How do I inject _repo?
Thanks again.
