Ninject + Bind generic repository

Question

I'm trying to Bind a generic IRepository<> interface to my generic Repository<> - however it always return null?

I have tried various things like:

Bind(typeof(IRepository<CustomerModel>)).To(typeof(Repository<CustomerModel>)); 
Bind(typeof(IRepository<>)).To(typeof(Repository<>));

However if I pass in a non-generic interface and class then it works like a dream?

Bind(typeof(IRepository<>)).To(typeof(Repository<>));

This is the correct syntax for binding an open generic.

If you are receiving null back when requesting IRepository< of whatever >, then there may be some other problem in an area of code you haven't shared.

Perfect! - Yes you were right. My Repository consturctor depended on a Interface - I now also have binded the Interface used by my Repository and it works! - Thanks. – ebb Dec 06 '10 at 20:37

@qes What would be the syntax if IRepository takes more than one type argument (i.e. `IRepository`). Please see http://stackoverflow.com/q/6740992/88709 Thanks. – Daniel Liuzzi Jul 19 '11 at 00:26

See my answer on MVC3 Controller constructor + Ninject.

Generic Binding works correctly in Ninject. Try using a parameterless constructor in Repository. I think the problem is there.
