Register multiple singletons with same interface but different constructor parameters

Question

I have 2 storage (Azure) accounts lets call them src and dest and I have controllers that require access to both and I\'m trying to work out how to register these 2 singleto

Answer 1

I would suggest defining two new interfaces:

public interface IBlobAccessClientSource : IBlobAccessClient
{ }

public interface IBlobAccessClientDestination : IBlobAccessClient
{ }

And then registering them both individually (in whatever way that SimpleInject supports).

Then in your consumers, inject in IBlobAccessClientSource and / or IBlobAccessClientDestination as needed. This will ensure that there are two singleton registrations - one for each of the two interfaces.
