C# 4.0 supports optional method arguments. Related to this is support for named parameters in function calls. For us it makes easier to use methods which have long argument list. It also introduces some new dangers which may lead us to messy and hard to understand code. In this code I will show how to use optional arguments and give some hints how to avoid messy code.

Source code documenting is very important task. Code documentation servers as persisted communication between developers who are using same code. Undocumented or poorly documented code may be hard to understand to other developers who have then waste their valuable time to struggling through the code they don’t understand well. In this posting I introduce you some code documenting tips.
