I wanted to repost the index of all the Little Wonders and Little Pitfalls posts and presentations so that they would be readily visible for anyone new to these series. I also linked in my C#/.NET Fundamentals presentation "Of Lambdas and Linq", a short primer for those just starting with LINQ and lambda expressions.

C# is a wonderful language for modern programming. While everything in C# has a reason and a place, occasionally there are things that can be confusing for a developer who isn’t aware of what is happening behind the scenes. This is another post in the Little Pitfalls series where I explore these issues; an index of the Little Wonders and Little Pitfalls posts is here. Many times, we create overloaded methods or constructors to allow them to accept different kinds of data. Further, there are times ......

This Friday and Saturday I will be giving my C#/.NET "Little Wonders" and "Little Pitfalls" presentations to the St. Louis Day of .NET Conference in St. Louis, Missouri at the Ameristar Casino and Conference Center. I'm including the presentations here for the attendees and anyone else interested. The C#/.NET Little Wonders presentation has been touched up a bit.

This is my fifth post in the Little Pitfalls series where I explore these issues; the previous Little Pitfall post can be found here. Side Note: I’ll be presenting sessions on the Little Wonders and the Little Pitfalls at the St. Louis Day of .NET conference on August 5th and ......
C# is a wonderful language for modern programming. While everything in C# has a reason and a place, occasionally, there are things that can be confusing for a developer who isn’t aware of what is happening behind the scenes. This is my fourth post in the Little Pitfalls series where I explore these issues; the previous Little Pitfall post can be found here. Today we are going to look at a potential pitfall that can bite developers who expect the default behavior of declaring the same method (with ......
C# is a wonderful language for modern programming. While everything in C# has a reason and a place, occasionally, there are things that can be confusing for a developer who isn’t aware of what is happening behind the scenes. This is my third post in the Little Pitfalls series where I explore these small pitfalls; the previous Little Pitfall post can be found here. In the last Little Wonders post, we talked about the Nullable static class (not to be confused with the Nullable<T> struct) and ......

This is my third post in the Little Pitfalls series where I explore these small pitfalls; the previous Little Pitfall post can be found here. This week we’re going to look at operator overloading. Yes, I bolded that because it is very important to note we overload operators, ......
Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. Today we’re going to look at an interesting Little Wonder that can be used to mitigate what could be considered a Little Pitfall. The Little Wonder we’ll be examining is the System.Nullable static class. No, not the System.Nullable<T> class, but a static ......
Starting a new series to parallel the Little Wonders series. In this series, I will examine some of the small pitfalls that can occasionally trip up developers. Introduction: Of Casts and Conversions What happens when we try to assign from an int and a double and vice-versa? 1: double pi = 3.14; 2: int theAnswer = 42; 3: 4: // implicit widening conversion, compiles! 5: double doubleAnswer = theAnswer; 6: 7: // implicit narrowing conversion, compiler error! 8: int intPi = pi; As you can see from the ......
This week in C# Fundamentals, we'll tackle the basic differences between C# struct and class types. Sure, this has been discussed many times by many different people, but I believe it's one of those subjects that needs to be brought up over and over again to help people new to the language and refresh people who may have forgotten all the minutia. Introduction: So, what is the difference between a struct and a class? Well, if you have only ever been exposed to the Java world, there is no concept ......
C# Fundamentals Genesis I’ve decided to begin a line of back-to-basics blogs that I hope to post regularly. I used to teach C++ Programming, Algorithms, and Data Structures courses at Webster University in the evenings here locally, and have missed those teaching and mentoring moments when I had to stop teaching after the birth of my twins (no more free time for me!). While some of these fundamentals will be obvious to those who know the languages well (I hope to post C# and C++ tidbits), I’m hoping ......
