AsNoTracking() is a powerful method from DbExtensions class. And for sure – the method you should know and use 😉. Continue Reading
Reading Microsoft documentation when we have all that stackoverflow questions with answers usually seems a waste of time. And as a typical, lazy programmer I admit that (much too often) I agree with that sentence 😉. But today I decided to check how Enumerable.Empty<T>() works and wasn’t satisfied with the knowledge I got. I started digging a little bit deeper and wasted some of the precious beauty-sleep time so if you want to know what’s happening when you add an element to an empty collection, let me tell you a story of today’s night.
No, not that story, you sick head! Continue Reading
This is the last post about C# 8 planned features and today I will write about Index type, recursive pattern and changes in switch construction. I will also teach you how to make new friends while programming. I hope you will not argue, that reading this post will pay off ;). Continue Reading
If you were online at least once in the previews week you probably noticed the biggest announcement from Microsoft! Yeah, everybody is talking about C# 8 planned features. And because the news is literally everywhere, I gave up and decided not to repeat what everybody already read. But that decision is no longer valid because back THEN (which means – yesterday or so) my pet project wasn’t so nasty and I wasn’t so stuck in the middle of some stupid, trivial task that seems to be unable to accomplish… So yeah, I changed my mind, I will wrote about C# 8, just to avoid touching (for at least a day 😉 ), the disaster I programmed :D. No, it’s not procrastination, not at all! 😉
Reading application’s logs is not a big fun but let’s be honest – it is part of our job and we will not avoid it. So why don’t we make it slightly more pleasant?
Stack traces explorers to the rescue! Continue Reading
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
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
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
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!
