.NET C# Gunnar Peipman2 Views 0 Comments Hopefully the era of leprosy and corona is over for this time and it’s time to get back to blogging. Exceptions are powerful feature of object-oriented languages as far as they are used like they are thought to use – throw exception only when something really unexpected happens. This advice should be taken seriously – here’s why. Back in days when I was young and beautyful (now I’m only beautyful) I found utility application to get documents and their metadata...

With each new release of C#, pattern matching improves for C# developers. While developers do not widely use pattern matching today, we’ll likely see its adoption grow as more teams and applications move from the Full Framework (.NET 4.8) to the runtime’s newer variants (.NET 5+). Like most unique features to the language, there’s always an initial knee-jerk reaction to either embrace it, use it everywhere, or outright hate it. Regardless of what camp we fall under, we must understand some everyday use c...

Fuzzy search allows finding strings that match the pattern approximately. It is a feature needed in almost every app, but it can be a little problematic to implement. We will focus on EFCore PostgreSql provider as it is free and seems to be the most popular choice nowadays (for me at least). First, our EFCore project needs this package: Npgsql.EntityFrameworkCore.PostgreSQL.FuzzyStringMatch Then, we need to register it with our DbContext, so let’s navigate to Startup.cs and edit our registration like s...

Introduction Today I would like to suggest a less-common but in my opinion a much better way to organize our codebase. Meet the Feature Folders.Problem For ages we have been (at least in the .NET environment) used to thinking about our code structure taking into account the technical aspects. For example MVC application project templates assume the division our objects into separate directories – Controllers, Views, Scripts and so on. We can see the same in many tutorials. If we need add new feature, f...

When a new project is in the start-up phase all models are relatively small, simple, and do not have a lot of relations. This makes the tests easy to arrange and also easy to read. Because the team ...

While this post is addressed to F# .NET developers, it introduces much wider concepts starting from hardware architecture to overall .NET runtime and JIT compiler optimizations. It shouldn't be a surprise - optimizing the application performance requires us to understand the relationships between our high level code and what actually happens on the hardware. There's a popular opinion that F# code must be slower than equivalent C# code. This opinion is mostly false, however it comes with some rationale. ...
