On September 26, we hosted a free virtual event – .NET Day Online ’23. This was the fifth annual edition of the conference, and we were absolutely amazed at how lively the conversation was! We’d like to extend a huge thank you to the wonderful speakers who joined us to share their passion for the work they do.  This year we decided to experiment with the format and fit everything into one full day, instead of staggering the content over two days as in previous years. Over 6,000 people registered for the 11-hour event, and we were thrilled to host them. For those who couldn’t join us – the ..read more

In recent .NET versions, there’s a new way to build JSON-based APIs with ASP.NET Core: Minimal APIs. Inspired by previous attempts in the ASP.NET ecosystem and elements from other communities, the Minimal APIs approach is an attempt to simplify the development of JSON-producing HTTP APIs. This post explores why it makes sense to use Minimal APIs, the programming model compared to ASP.NET Core MVC, and some drawbacks that might make you consider using it. Why ASP.NET Core Minimal API? Over several versions of .NET Core and .NET, performance has been a central focus of the .NET team. While ASP.N ..read more

As a developer, you deal with many data formats, some of which are friendly to humans while others are optimized for computers. It’s not often you need to look directly at complex data formats, but it can help when debugging nagging problems in your codebase. If you’ve been building applications for any time, you’ve likely run into the following commonly-used data formats: HTML, XML, JSON, JSON Web Tokens (JWT), and URLs.  With the release of JetBrains Rider 2023.1, we’ve introduced a new set of debugging visualizers to help you make sense of the data in your application’s memory. Each vi ..read more

When working with databases, there are a few tenets to keep in mind to maximize your application’s performance. First, reduce the number of network calls. Second, reduce the complexity of your queries. Third, reduce the data retrieved in your result set. If you’re an Entity Framework Core 7 user, you can strive to meet these using JSON columns. JavaScript Object Notation (JSON) is a language-independent format widely used across many technologies and ecosystems. However, while JSON support has been available in most database engines for quite some time, the EF Core team only recently released ..read more
