Question

So I have an Interface as follows

public interface IMembershipProvider
{   
    bool GetUserGuidFromSSOToken(string ssoToken, out string userGuid, out int statusCode);
}

And a Class as Follows which Implements the above Interface

public class MembershipProvider : IMembershipProvider
{
    public bool GetUserGuidFromSSOToken(string ssoToken, out string userGuid, out int statusCode)
    {

       ....Method Contents
    }
}

And then in my Presenter I have the following

private IMembershipProvider Provider;

..

if (!Provider.GetUserGuidFromSSOToken(ObSSOCookie.Value, out userGuid, out statusCode))

And when this is called it use the code for the method from MembershipProvider class, but I am just wondering how that’s possible when the MembershipProvider is never referenced in the Presenter ?

Answer 1

The MembershipProvider instance must be injected into the Presenter using dependency injection.
