And that’s all because some time ago, somebody at Microsoft had, let’s say, not a best idea :P. But what’s the problem? Path.Combine can be used with one, two, three or even four arguments. In an ideal world the first argument should be passed as an absolute path and...

This is video is the start of a brand new series of videos about C# / CLR internals. We're going to look at C# Switch Case Internals and what interesting things happen under the hood and how well it performs as compared to if-else statements.

In this video, we're going look in what situations JIT will emit bounds check for arrays and how to force it to generate bounds-check free code. Bounds Check elimination is something that we want to do to increase performance since each check has a cost associated with it especially that it will emit a possible branch. ♦ link to loop clone video: https://youtu.be/zxcHkEu6aTY

Omówienie ogólnych zasad jak powinno używać się wyjątków w C#.

This video talks about the "Skip" method, and differences in implementation between dotnet frameworks. Also, we will try to implement a less flexible but faster version of the "Skip" method. Enjoy. 🙂

This video will show you some of the performance and allocation problems that you might encounter when writing LINQ expressions and offer a couple of solutions on how to solve them. LINQ Links: ♦ https://github.com/NetFabric/LinqBenchmarks ♦ https://github.com/NetFabric/NetFabric.Hyperlinq

Obszerny artykuł o hermetyzacji w programowaniu obiektowym na przykładach w C#.

Artykuł kierowany dla osób, które chcą zostać programistami .NET. Dowiesz się nim podstaw programowania obiektowego, to znaczy czym jest dziedziczenie.

How I built a very simple macro system for C# that works right in the code editor

Jak zbytna ufność temu, co wygeneruje resharper czy visual studio zmarnowała pewnej blondynce 8h pracy (a łącznie firma straciła na tym błędzie 10-12 godzin). A wystarczyło czytać.
