One of ASP.NET MVC errors wasted one hour of my life today (of course, it is many times less than this season’s leader SharePoint) but this is still one hour. “The view 'Index' or its master could not be found. The following locations were searched” error raised suddenly and I was not able to get over it. Well, this time solution was simple.

Loggers are one of most popular examples about interfaces for sure. And there are a lot of implementations of loggers. Some implementations are simple and yet powerful, some implementations may be more complex. All we have to is to select implementation we need and integrate it to our application. It seems like good idea at first place but as soon as we need to switch from one implementation to another we discover nasty dependencies we have to change in all places where we are logging. Let’s see how to avoid these dependencies.

I’m sure you have seen classes that initialize a lot of objects in their constructor. These classes may be hard to test because of those object creations I mentioned. To get around this problem we use Extract and override factory method refactoring so we can extend these classes and override some factory methods.

Sometimes you are not able to use Extract Interface refactoring because interface of parameter may be too large or there may be no interface at all. You just have class to pass in and you are not able to fake it or extend it to get class testable. In this case you have to use Adapt Parameter refactoring to create adapter that is seen through common some common class of interface.

One extremely useful utility for SharePoint is SharePoint Manager 2007. SPM2007 is developed by Carsten Keutmann. You may know him better by his other project – WSPBuilderthat is one of the best SharePoint add-ins for Visual Studio.

Ship it! A Practical Guide to Successful Software Projects, the book I introduced couple of days ago, introduces something called The List. The List is your task list that tells you what tasks you have, how long they would take to get done and when one or another task should be done.

In good code variables are used as short as possible. Often we can see code where variables are defined in wider scope than it is necessary. There are many examples about too wide scopes. One of fuzziest of them is variable that is defined in class scope but it used only by one method and this method uses this variable as local variable. But variable life time can also be reduced in local scope. To achieve this we use refactoring method called reduce variable scope.
