Sam July 9th, 2021 API versioning can help evolving our APIs without changing or breaking the existing API services. URL segment, request header, and query string are three ways to achieve API versioning in ASP.NET Core application. ASP.NET Core OData 8, built upon ASP.NET Core, has the built-in API versioning functionality via route URL prefix template. For instance, the following code configures a version template in the route URL prefix to achieve URL based API versioning: services.AddControllers(...

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...

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...

One of the questions I frequently get asked by people who watch my Durable Functions Fundamentals Pluralsight course is whether you can use dependency injection with Durable Functions (as my demo app uses static methods). The answer is yes, and it's quite simple although there are a couple of considerations about logging that are worth pointing out. In this post I'll give a quick overview of the main steps, and you can get more details on the official docs site if you'd like to dive further into the top...

5th July 20215th July 2021Steve Gordon.NETPart 1: Why do we need a StringBuilder and when should we use one? After becoming proficient in .NET and C#, developers are likely to learn that they should use a StringBuilder to optimise string manipulation and concatenation. This is not a hard and fast rule for all situations but is generally good advice if your code combines or modifies strings repeatedly, particularly if the number of modifications is unbounded and not known until runtime. In this post, I ...

Experiments in self-contained native executables in .NETComment on this post [3]Posted in Open Source Sponsored By One of the best parts of the .NET ecosystem is the excitement around experimentation. Someone is always taking .NET to the next level, trying new things, pushing the envelope. Michal Strehovsky has an interesting experiment on his GitHub called "bflat." This is not a produc...

Recently, I had to convert an SVG file to PNG. I tried a few free online converters, but none of them were able to convert the image correctly. Indeed, they don't support custom fonts… Instead of wasting more time at searching for an existing tool, I opened Visual Studio and I made a quick application to convert my images!

The other day at work I ran into an attribute I hadn't heard about, the [Conditional] attribute. In this post I start by describing conditional compilation using pre-processor directives like #if, and then introduce the [Conditional] attribute, and describe how it differs to using #if.Conditional compilation with #if With the release of .NET Core 5 years ago (has it really been that long?!) the need to multi-target .NET libraries and applications became more prominent. As the early versions of .NET...
