System.Tuple is a set of generic utility classes that lets a lazy developer get away without creating a separate class. At first sight it might look handy, but it isn’t. It’s a code smell.

And it is full functional coverage that really matters in the end. Look at a simple method that formats a… Continue reading Code Coverage != Functional Coverage
Adding an Overload is a Breaking Change
Adding functionality to a library, without touching the existing code should be safe for clients, shouldn’t it? Unfortunately not, adding another overload to a library can be a breaking change. It might work when the library is updated, but suddenly break when the client is recompiled – even though no code was changed. That’s nasty,… Continue reading Adding an Overload is a Breaking Change

Knowing (and creating) shortcut keys for those operations not only saves time, but keeps focus on the code. Reaching for the mouse might not take much longer time, but it switches the brain over to mouse-control mode… Continue reading My Favourite Visual Studio Key Bindings
