We had a ton of stuff go down in the world of C# .NET this year. The big news was all about generative AI, ChatGPT, and Copilot, but the .NET team and the community didn’t take a sabbatical. We had loads of conferences, announcements, new frameworks, and cool tools. There was a fresh C# version release, a new .NET version, and plenty more. Yours truly went over all the 2023 announcements, the most popular conference sessions, the top tool releases, and the most-loved blog posts of the year.

I don’t think I have to make the point of how important tools are. What would we do without IDEs like Visual Studio? Or without good email clients like Gmail and Outlook? For power users like software engineers, good tools can 10x your productivity. Everyone got their favorite tools, and I think I gathered a pretty good list. So here’s my list of tools that I use every day and highly recommend.

C# has been through a lot of change in the last decade. From open-sourcing the language to a new cross-platform framework to yearly releases instead of 3-year iterations. Meanwhile, new languages, new frameworks, and new paradigms have taken off in the software industry, including the rise in popularity of Node.js , TypeScript, Kotlin, Rust, Go, and Python. Through it all, C# and .NET stayed relevant and popular . In this blog post, we’ll glimpse the day-to-day activity and challenges the C# language design team faces.

Disclaimer: This blog post was written by a protein-based intelligence. in a previous blog post , I showed you how to use PostgreSQL in C# with Npgsql, Dapper, and Entity Framework Core. But if you’re going to use one of them, it’s probably a good idea to make sure you’re not choosing a library that has really bad performance. Or at least to understand how much it’s going to hurt.

One of the most used databases these days is PostgreSQL (aka Postgres). Its accomplishments include being the most popular DB [among professional developers] according to Stack Overflow survey of 2022 , the database in all of the fastest TechEmpower benchmarks , and being the most advanced open source database (self-proclaimed). We’ll talk today about combining Postgres with my favorite language and runtime: C# and .NET. Just because Postgres isn’t a first-party Microsoft database, like SQL Server, doesn’t mean you don’t have full support for it in C#.

Oren certainly makes a unique impression. Having listened to a lot of CEO interviews in countless podcast episodes, I never encountered another CEO more knowledgeable about the intricacies of C# than Oren. As we sidetracked into his many adventures in developing a database, Oren’s talked about .NET garbage collection, ...

Six productivity tips when using ReSharper or Rider

After going through a bunch of code interviews, here's some things I learned from coding problems that I never use in my day-to-day.

In this article, you'll see how frameworks like Entity Framework and MongoDB C# driver use expressions trees to make that conversion. And you'll see how to use expression trees yourself to build dynamic queries. Those are queries that you aren't able to create at compile time because you'll know how the query should look like only at runtime.
