Learn how to improve performance using scalability with the async and await keywords. When are asynchronous code able to help us and when will it make our performance worse.
We want good performance in our software, and we can get good performance in two ways. 1. Refactor the software to do its tasks faster. 2. We can improve the software scalability so we can handle more concurrent tasks.
Asynchronous code targets scalability making us use the resources of our servers better.Continue Reading
The latest update in the C# in a Nutshell series, it obviously covers C# 7.0. With 1037 pages it is a massive volume, most of it can be used as a reference book, and many of the chapters are not important unless you have very specific needs. The topic in each chapter is covered in significant detail, you will be hard-pressed to find a detail that is not covered I think.
It can be read, cover to cover, but I would recommend to read the first 4 chapters and pick from the remaining based on interest or need. The detail level and reference book type of writing make the book dry to read, so be warned!
My notes from the book are collected here, I hope they will be useful to someone.

The book is published in 2014 so it is starting to show some age. Even though ASP.NET MVC 5 is the last version until it changed the name to ASP.NET MVC Core which is in version 2, see the version history here. So why read a four year old book? Many projects still use MVC 5 and it allowed me to gain an overview of the technology before diving into MVC Core. Unless you have a particular interest in MVC 5 I would recommend a book about MVC Core instead.
At 624 pages and 17 chapters, I read it in a couple of weeks. It does start to show it’s age when referencing jQuery and AngularJS, it is rather old versions mentioned. But the chapters about the MVC framework are sound and contains a good walkthrough about each main feature of the framework. If you need a primer on MVC 5 I will recommend it.

When you have worked in a specific area for a long time, many of the tasks begin to be repetitive. One way to keep sharp is to engage the brain with programming puzzles. A site that contains many puzzles is hackerrank.com. The name is a bit over the top for my taste, but they keep an extensive list of many different programming challenges.
Each challenge is solved in the programming language you choose. It makes a great way to both keep the skills up to date and practice using programming languages that you do not use that often. Especially the challenges that are rated medium and up are good for keeping your skills sharp.
I have tried to tackle one of the most difficult challenges; spy game revisited if you keep on reading there will be spoilers so if you want to solve the problem your self, please stop reading. I will implement the solution using C# .NET. You can find the code here.
