I have just changed from Ninject to TinyIoC for dependency injection and I'm having trouble with constructor injection.
I have managed to simplify it down to this snippet:
public interface IBar { }
public class Foo
{
public Foo(IBar bar) { }
}
public class Bar : IBar
{
public Bar(string value) { }
}
class Program
{
static void Main(string[] args)
{
var container = TinyIoCContainer.Current;
string value = "test";
container.Register<IBar, Bar>().UsingConstructor(() => new Bar(value));
var foo = container.Resolve<Foo>();
Console.WriteLine(foo.GetType());
}
}
which causes a TinyIoCResolutionException to be thrown with:
"Unable to resolve type: TinyIoCTestApp.Foo"
and inside that exception is a chain of inner exceptions:
"Unable to resolve type: TinyIoCTestApp.Bar"
"Unable to resolve type: System.String"
"Unable to resolve type: System.Char[]"
"Value cannot be null.\r\nParameter name: key"
Is there something wrong with the way I'm using the constructor injection? I realize I could call
container.Register<IBar, Bar>(new Bar(value));
and that does indeed work, however the result is a global instance of Bar which is not what I'm after.
Any ideas?
