Example usage of TinyIoC - the first with constructor injection, the second with property injection.
namespace TinyIoCDemo
{
// This is the interface for my aspect - the dependency for my classes.
public interface IAspectDependency
{
string GetGreeting();
}
// And here is an implementation.

{
#region IAspectDependency Members
public string GetGreeting()
{
return "Hello World!";
}
#endregion
}
}
namespace TinyIoCDemo
{
// My greeting class that gets its greeting aspect via the constructor.
public class GreetingWithDependencyCi
{

public string GetGreeting()

// When I ask the container for an IAspectDependency, is will always provide the same GreetingAspect.
