A Topsy-Turvy World The constructor signature for AuthorizationChecker now looks like this: public AuthorizationChecker( ISettingsStorageProviderV30 settingsProvider, IAuthTools authTools, IAclEvaluator aclEvaluator) { ... } We can clearly see that AuthorizationChecker depends…

We’re now on the eighth installment of Extreme ASP.NET Makeover. In part 7, we examined the singleton pattern and refactored away the AuthChecker singleton. AuthorizationServices, which previously used the AuthChecker singleton, now depends on the IAuthorizationChecker interface and simply…

Extreme ASP.NET Makeover: Death of a Singleton-Refactoring Now that we have a new class, complete with functionality, we can start to refactor other parts of the application to use it instead of the AuthChecker singleton.  Like all the other refactorings we’ve done thus far in this article,…

Extreme ASP.NET Makeover: Death of a Singleton-AuthChecker Class I’ve Got Some Seeds, Right Away So where should we start?  How about the AuthChecker class, since that’s what we’ve discussed through the first part of this article.  Earlier, we decided that there was no reason for it to…

Extreme ASP.NET Makeover: Separation of Concerns – The Big Picture   Let’s summarize what we’ve done. We removed code from Page_Load using cut and paste, and we created two new classes. It doesn’t seem like much as far as refactoring is concerned. But that’s because we aren’t actually…

You have heard of and probably used patterns in your projects. But have you heard of the "Mickey Mouse" pattern. In this short video, Ward Bell, gives you a quick overview of this unheard of pattern.Ward delivered a great session at the last summit and is coming back to…

As we mentioned in our earlier post, we release a drop from our SharePoint Guidance project every two weeks which is the duration of our iteration. We released Drop 10 to our CodePlex project site last week. In this webcast, Erwin van der Valk and Francis Cheung are…
