Home of the AlmostImplementedException


Some days ago i got the problem, that I have to use a custom dictionary with as parameter for a service – therefore it must be serializable. I found an interessting solution from “Paul Welter” at his blog (XML Serializable Generic Dictionary). But that’s not all! I had to implement the Constructors for Dictionary and […]

Lets get dynamic with ExpandoObject

With .Net 4 Microsoft introduced the ExpandoObject (funny name). With this object you can dynamically add and remove properties. Thats very useful to get rid of this ugly CleanCode you produce every time ;-). Seriously, don’t use this class except for very special occasions, like producing a dynamic object where you don’t care what properties […]

cast vs “as”

Another good example for our categories “difference between a duck” AND “CleanCode” is an ordinary ()-cast against “as”-cast. Why is it in both categories? Both do roughly the same thing and its more a question of code-style which one you use. But more important both use different ways to approaching the same problem and thats […]

As an (bad) example I want to refer to 8 Most common mistakes C# developers make and in particular point 7 “using foreach instead of for”. So whats wrong with this kind of post? First of all, it refers to […]
