In the “classical unit tests” developers quite often use Arrange/Act/Assert comments to annotate the main parts of the test method script. However, the test case scenarios in component tests tend to be more complex and those simple notations don’t fit anymore. Here's my proposition on how to deal with that problem...

Wprowadzenie do EF Core

I gathered my notes from playing with C# records and Nullable Reference Types. Read more if you want to learn if you can use them e.g. for Value Objects or want to do Type-Driven Development.

In the previous posts in this series, I took a first look at the internal design of StringBuilder class as a linked list, and then looked at the source code behind the constructors and Append methods. In this post I look at (arguably) the most important method on StingBuilder, ToString(), and show how the final string is created from multiple chunks. I also looks at the overload ToString(startIndex, count), and show how recent implementations differ from that used in .NET Framework.Terminology recap In ...

Jak przekazać kontekst? I co w ogóle oznacza kontekst? I dlaczego Dependency Injection nie zawsze jest odpowiedzą. Zapraszam.

When I started my career, SQL Injection and Cross-Site Scripting were perceived as sophisticated attacks. Mature admins installed MSSQL servers with the Internet turned off, because by default, open to the world was a potential source of the attack. Setting up the firewall wasn’t even a standard. Today we have easier. By using the cloud, many things are warranted. Suppliers protect us from basic break-ins. For instance, they’re blocking DDoS attacks and many other attacks that we don’t even know existed...

8th July 20218th July 2021Steve Gordon.NETPart Two: Understanding the Overhead of a StringBuilder To continue exploring how the StringBuilder works, we’ll shift focus and study its logical design. Today, we’ll start by looking at how the type is designed and the overhead involved with creating and using StringBuilder instances. If you missed part one of this series, I explained why you may decide to use StringBuilders in your application code for more efficient string manipulation. Don’t worry if you mi...

On this page: If you've been following this blog and my Twitter feed, you know I've been going through a lengthy process of updating the Markdown Monster WPF desktop application from using an WebBrowser control based editor and preview interface to using the new WebView2 control. This new control provides a modern browser that use the Chromium engine which provides much better compatibility with modern Web Standards than the old Internet Explorer based WebBrowser control. The new control has strict r...
