C# 8.0 just rolled out with plenty of new features. One of the most important is the support of nullable reference types (NRT). A bunch of words that don't seem to explain what it does. I mean, aren't all types (except value types) already nullable?

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.

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.

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.
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.
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.

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.
Overview
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.

F# fits that bill perfectly.

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.

Recently nullable reference types have become trendy. Meanwhile, the good old nullable value types are still here and actively used. How well do you remember the nuances of working with them? Let's jog your memory or test your knowledge by reading this article. Examples of C# and IL code, references to the CLI specification, and CoreCLR code are provided. Let's start with an interesting case.
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.
