C# (pronounced see sharp, like the musical note ) is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, declarative, imperative, functional, generic, object-oriented, and component-oriented programming disciplines. It was introduced in 2000 by Microsoft as part of its .NET initiative, and later approved as an international standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2018).
The With…End With statement in VB allows you to execute a series of statements that epeatedly refer to a single object. Thus the statements can use a simplified syntax for accesing members of the object. For example: Is there a C# syntax equivalent? No. There is not. The closest thing to it would be the…
Starting from C# 12, it is possible to define a primary constructor within classes and structs. The parameters are placed in parentheses right after the type name. The parameters of a primary constructor have a broad scope. They can be utilized to initialize properties or fields, serve as variables in methods or local functions, and…
C# is a modern, general-purpose, object-oriented programming language developed by Microsoft. It is widely used for Windows desktop applications, games (especially using the Unity engine), and web development through the ASP.NET framework. C# is considered to be beginner-friendly and is a great language for new programmers. Below we explore some of the reasons why C#…

Starting with C# version 12, you can specify default values for your parameters in lambda expressions. The syntax and the restrictions on the default parameter values are the same as for methods and local functions. Let’s take an example: This lambda can now be consumed as follows: params array in lambda expressions You can also…
All right folks, generic attributes are finally a thing in C#! 🥳 You can define one just as you would define any other generic class: And use it like you would use any other attribute: Generic attribute restrictions When applying the attribute, all the generic type arguments must be provided. In other words, the generic…
The file modifier restricts a type’s scope and visibility to the file in which it is declared. This is especially useful in situations where you want to avoid name collisions among types – like in the case of generated types using source generators. A quick example: In terms of restrictions we have the following: On…
C# 11 introduces the concept of raw string literals to the language and with that come a set of new features for string interpolation as well. First of all, you can continue to use the interpolation syntax as you know it in combination with raw string literals like this: The output will be: Escaping braces…
Raw string literals are a new format which enables you to include whitespace, new lines, embedded quotes, and other special characters in your string, without requiring escape sequences. How does it work: A quick example: This will output the following: Whitespace before the closing sequence The whitespace before the closing double-quotes controls the whitespace which…
Feature is not available in C# 10.0. Please use language version 11.0 or later. There are two ways to approach this: Language version is greyed out and cannot be modified The Language version cannot be changed from the Properties window of the project. The version is linked to the target .NET framework version of your…
.NET 6 introduced a few new helper methods to deal with throwing exceptions, and one of them is ThrowIfNull. The usage is simple: The method will throw a ArgumentNullException when myParam is null. It will do nothing otherwise. ThrowIfNull can take in two parameters: Note: paramName uses CallerArgumentExpressionAttribute to retrieve the name of your parameter…
