Imagine there’s no… NullReferenceException! (C# 8 plans)

Well, maybe not a totally ‘no’ NullReferenceException, but a whole lot less than now. Well, yeah, I had to catch your attention somehow :P. But anyway, have you heard those rumors about C# 8, how amazing it is going to be and how hard Microsoft is working on the release…? If not, you definitely should read this post! Because the promised changes sound really good and will be a must-to-know quite soon.

So today I wanted to write about one of the “louder” planned features – nullable reference types. Yes, you read it right. And yes, all the reference types we already have in C# are actually… nullable. Yeah, makes no sense, yeah, what a bullsh… No! Wait! Continue Reading

Want to work at Microsoft? You need to read this!

I’ve always had the impression that companies like Microsoft or Google are some magical places in the far-far-away-land (yep, America seems quite far away for a European kiddo 😉 ). People working there must be some kind of amazing scientists who write their code by setting the appropriate voltage directly on transistors. Or, at least, use assembler-like languages every day 😉.

If you have a similar idea, you may like to read some facts I discovered after talking to one of Microsoft employees. My todays ‘guest’ is Ela Mościcka who’s been working at Microsoft for +3,5 years as a Talent Sourcer. And probably the most busy person I’ve met so far :D. We are talking about working at MS and how a programmer can become a MS employee. Continue Reading

C# stuff nobody told you – delegate is a class! And there is a good reason for that!

Have you ever wondered why blue screens of death happen so rarely, nowadays? Of course, we can thank Microsoft for this but the way they fixed this problem is not so obvious! According to Marino Posadas (and his book Mastering C# and .Net Framework) back in 2010, Microsoft made an analysis of this topic and they came to the conclusion that the 90% (wow!) of the blue screens were caused by drivers! So, Microsoft made manufacturers to follow the Hardware Compatibility List. That somehow solved most of the problem but what with the rest 10%? Most of them was due to the… Continue Reading

C# Delegates – a fairy tale about when (and how) to use them.

Many people neglect C# delegates because they cannot find a reason to use them. On the other hand, there is (rather small) group of people who overuse delegates in code that could be easily replaced by literal method call. So when should we use delegates? Well, they show their real power in situations when we need a mechanism to easily switch from one logic to another, without changing our application’s core code. Continue Reading

C# stuff nobody told you – enum is a b*tch!

New year, new me… Just kidding, no running or yoga plans, but I decided to have a (temporary) break with ‘C# attributes you should know’ series and start with a brand new one – C# facts that somehow surprised me. For the first article, I will show you how (friendly looking, always helpful, good guy) enum can become an asshole. An asshole who will steal your precious time!

C# attributes you should know #3: [DebbugerBrowsable] and [DebuggerDisplay]

Today I again focus on the attributes that will make your debugging less painfull :). This time my scribbles should appeal to the programmers who prefer keeping their code clean (and adhere to the principle: the less ‘spare’ code the better).
So grab a mug of whatever you like and take a look at DebbugerBrowsable and DebuggerDisplay . The first one may be a good alternative to DebuggerTypeProxy I described in previous post and the second one is just ‘a must’ (really!) that makes life easier. Continue Reading

C# attributes you should know #2: [DebuggerStepThrough] and [DebuggerHidden]

Last time I wrote about C# attribute DebuggerTypeProxy that helps us customize the way we display our type’s data while debugging. Today I would like to introduce you to the world of attributes that helps you skip some parts of code while debugging. Most of the C# programmers probably know them well, but I realized that only a few can tell the differences between them. So, ladies and gentlemen, let me introduce you the DebuggerStepThrough and DebuggerHidden. Continue Reading

C# attributes you should know #1: [DebuggerTypeProxy]

[DebuggerTypeProxy] is very useful attribute when you have a class that inherits from another class and that one inherits from another one, and some of the classes contain collections of items and hundreds of properties that in fact are not important to you… Strictly speaking, when displaying class’ members while debugging makes you feel like quitting the job.

C# Attributes – introduction

C# Attributes are very popular for ‘decorating’ assembly with some additional data, usually influencing on the application’s behavior or the way data are managed. You probably already used at least some of them – Obsolete, Serializable, Required, Display, MaxLength, RegularExpression, WebMethod are only a few of hundreds available in .Net world. What is more, you can write your own custom attribute and use it like a build-in one. I will write more about this in the next post. Right now, let’s focus on… Continue Reading
