A couple of weeks ago I wrote an article about building and deploying a Blazor app without touching a Windows machine and realized maybe I should take a step back and explain what Blazor is and why anyone would use it. It's still fairly new to most in the front end development world, but it's awesome and you should check it out.
Check out this post to see how you can use Python from inside a C# .NET Core application with a more modern approach than my original articles using Pythonnet.
Hi everyone! There is a lot of information about different C# features. About various life hacks and best practices in this language.
I want to tell you about equally useful, but less popular tips for working with this language.
Dapper is a popular and easy-to-use object-relational mapping (ORM) tool for .NET developers. It is lightweight, fast, and provides a simple way to execute SQL
Implicit operators are a C# feature that can make our code more readable and expressive. But beware! Misuse can backfire and cause a great deal of headaches!
We use Azure Function Core Tools to create a local.settings.json file and import our Function settings to that file so we can run our Functions locally.
I've recently gotten into using Docker in my development cycle and I'm really enjoying how much of a wonderful tool it is. One thing that always used to be a pain was setting up a development server to run SQL Server. Now with Docker, I can just spin up a Docker container and I instantly have a SQL Server ready to go.
I recently wrote a blog post introducing some of my favourite NuGet packages: My Top 4 NuGet Packages for ASP.NET Core. In that post, I briefly introduced a package called MediatR. Today, I will dedicate this post to revisiting MediatR in further detail.
QR code is a computer-readable identification that contains data about the item to which it is attached. The article demonstrates how to generate QR-Code image.

Compared to other languages, C# was way behind in capabilities to handle data efficiently. Well, those days are over now. Microsoft just improved the C# syntax, making it easier for developers to manage data in arrays.
We are always talking about the mainstream programming languages to an extent where Python, Java, SQL, etc, are all that we see mostly. There are many other dynamic frameworks and languages like our topic of choice today; C sharp or C#, which are playing an integral part in global software development communities. Let's take an in-depth look at the fundamentals of C# as well as the .Net framework to better understand the exclusivity, features, and their advantages.
Performance is often one of the key focus points when building enterprise software. Many of the systems that we build rely heavily on communications with other systems. When these external communications become slow, then our software becomes slow. Unfortunately, we often have no control over the response time of the services that we depend on. However, we can optimize the way that we communicate with those services in order to ensure maximum performance.

If you follow the Microsoft development community at all, you’ve most likely already heard of the new web development framework called Blazor. If you haven’t heard of it, here’s an overview from the product site:
When you think about database providers for ASP NET Core apps, you probably think about Entity Framework Core (EF Core), which handles interacting with SQL databases. But what about the NoSQL options? A popular option for NoSQL is MongoDB. So in this article we're going to learn how to create a simple ASP NET Core CRUD API using MongoDB as the database provider.
It is very glad to see that the web technology is improvising day by day. One such notable improvement is the introduction of WebAssembly and direct usage of them in evergreen browsers.
Object oriented programming (or OOP) is a style of programming that encapsulates data and behaviours into models known as objects. In this way, related code is grouped together and kept separate from other code, and provides reusable blocks that can be used to rationalise the problem at hand.
.NET 5.0 was officially released this week, bringing with it a range of improvements to the .NET ecosystem. Like many .NET developers, I was quick to download it and give it a test run. This article discusses some of the most exciting new features in .NET 5.
Hangfire is a .NET library that makes it really easy to adding background tasks to your .NET app. It supports one-off "fire and forget" tasks, as well as scheduling recurring tasks. On top of that it supports persistence, so all of your tasks will continue to exist even after restarting your app.
When looking for the perfect .NET reporting solution to design meaningful reports, there are quite a few factors you must consider when evaluating your options.

In this article, I look into some of the shortages of event-driven
programming and suggest behavior trees as an effective alternative,
suitable for back/front-end application development.
Exception handling is common to most programming languages, and the mechanism and behaviors are similar in most languages: try\catch\finally. It is well documented. We are not going to discuss that.
Dapper and EF Core are popular .NET libraries for data access and management. Both have strengths and weaknesses, and the choice will depend on the project's sp
Is it me or Functional programming (FP) seems to be trending lately? FP languages like Haskell, Elixir, and F# are stronger than ever and large frameworks try to adopt a more functional approach. Even C# tries to include functional constructs in the language.

Software development is a complex task and as a developer you gain nothing from "reinventing the wheel". I'm a firm believer that you should make your life as easy as possible as a developer, by using tried and tested packages where possible; it will take so much headache out of your development experience.

In the latest release of .NET 9, several enhancements have been introduced to LINQ, providing developers with more powerful and efficient ways to work with data
Extension methods are one of the coolest features of C#. It allows our custom methods to be used on the objects without needing to extend or change the underlying class.
Dependency injection (DI) is a wonderful thing. Simply add your dependency as a parameter to the constructor (most commonly) of your class, register it with you DI container, and away you go - the DI container will manage the rest. Some of the key benefits of DI are: greater testability, greater maintainability, and greater reusability.
Interface is mostly viewed as a useful feature to write more maintainable code. But the concept of Interface developed to address a different issue with C++.

edit: Unlike the conclusion of the post below, I based the analyzer on C# CaaS and not .NET IL. Its now available to use https://devsnicket.com/eunice/#csharp. The latter doesn't preserve the order of members of a class either in the dll or pdb. Although, after looking at some open source C# projects, this capability wasn't used by default.

Recently I've been learning how to write code in F#. For those who haven't heard of it, F# is Microsoft's/.NET's answer to a functional-first programming language. My motivation was to learn a functional programming language that would make coding for scientific computing and data analysis more expressive, concise, and maintainable, all while fitting seamlessly into the .NET ecosystem that I already know and love. F# fits that bill perfectly.

Type inference is a common feature among mainstream programming languages. The functional ones, like ML and Haskell, are pioneers in exploring this programming paradigm where the declaration of a variable or a function may omit a type annotation. Today, even classic imperative languages such as C++ offer, to a certain extent, a kind of type inference.
If you've spent much time around C# and .NET, it's likely that you will have come across LINQ (Language-Integrated Query), which allows you to use a range of powerful querying capabilities directly in the C# language.

This year was a special edition of MS Build; for obvious reasons, it was 100% virtual. I must say that I had my doubts at first, but I'm forced to admit that Microsoft nailed it. The experience was fantastic. I liked the personal schedule builder and the rebroadcast in 3 different timezones, to only name a few things. Microsoft even took the time to ship the conference's gear to all attendees, DIRECTLY to their doorstep, what a nice touch.
