When crafting code to showcase your talent, a productive development environment involves more than finding the best IDE (Integrated Development Environment) or text editor.

According to the 2021 survey contacted by StackOverflow, Visual Studio Code (VS Code ) emerged as the most popular IDE with 71.06% of all the respondents.

VS Code has been around for quite a few years and it has gained popularity more than any IDE in the market because:

  • It’s lightweight and is capable of running smoothly on low-end computers (4G RAM).
  • It comes functional out-of-the-box and supports a lot of programming languages like Ruby, TypeScript, JavaScript, Rust, Python, C++, C#, Java, Go, and more.
  • It is highly customizable, which gives you the ability to add a custom color theme, keyboard shortcuts, layouts, and other configurations to make it efficient for developing any application.
  • VS Code has a marketplace of over 35,000 extensions ready for download to add more functionalities to the IDE.

In brief, VS Code has almost limitless capabilities when the right extensions are installed and configured properly.

This article will reveal the top 10 best VS Code extensions to improve your productivity for C# and .NET development.

In the end, I will list some bonus extensions that will help you as a C# and .NET developer.

5 – Auto-Using for C#

Auto-Using for Csharp extension

The Auto-Using for C# allows you to auto-import from different namespaces and provides IntelliSense for references that are yet to be imported into the C# file.

When you start typing a symbol, the extension will display options from different namespaces, where you will use the up/down arrow keys to navigate the options and press the Tab key to select a specific option causing the extension to automatically add the using statement for you.

In case there are multiple completions with the same name, the extension will compress them into a single completion and allow you to choose between them.

6 – C# Namespace Autocompletion

The C# Namespace Autocompletion extension suggests the entire namespace for you to fill or you can choose the “namespace-fill” option and it will automatically fill the namespace according to the folder structure of your project.

7 – NuGet Reverse Package Search

NuGet Reverse Package Search vs code extension

The NuGet Reverse Package Search adds reverse .NET Core package lookup support in VS Code. This is similar to the “Add Package” context menu item in Visual Studio.

When you highlight a symbol and run the “NuGet Reverse Package Search” command from the command palette, the NuGet Reverse Package Search extension will tell you the package the symbol belongs to.

Sometimes when you type some code or a symbol that you think is valid but OmniSharp tells you it’s invalid, it might be due to a missing NuGet package.

To address this issue, just highlight the text or symbol and run the “NuGet Reverse Package Search” command from the command palette to search the package repository.

Once the results are found, you can choose the package from the drop-down list and the extension will automatically install the package in your project.

The AI was trained on both text and hundreds of millions of lines of code from the GitHub repository. Also, the AI can translate any natural language to code in real-time in the supported programming languages.

At the time of writing this article, GitHub Copilot is supported in Neovim, Visual Studio Code, and JetBrains

After installing the extension, you will get code suggestions as you type and you can press the Tab key to accept them.

For example, type the following code in any of the supported IDE (Neovim, Visual Studio Code, and JetBrains) and you should get code suggestions from GitHub Copilot:
