Visual Studio Code C# Intellisense

Posted on 30-04-2021 by admin

Welcome to the C# extension for Visual Studio Code! This extension provides the following features inside VS Code: Lightweight development tools for.NET Core. Great C# editing support, including Syntax Highlighting, IntelliSense, Go to Definition, Find All References, etc. Visual Studio comes with its own C compiler, which is actually the C compiler. Just use the.c file extension to save your source code. You don't have to be using the IDE to compile C. You can write the source in Notepad, and compile it in command line using Developer Command Prompt which comes with Visual Studio. The Microsoft C/C for Visual Studio Code extension supports IntelliSense, debugging, code formatting, auto-completion. Visual Studio for Mac doesn't support Microsoft C, but does support.NET languages and cross-platform development. For installation instructions, see Install Visual Studio for Mac.

Since the day that Microsoft released Visual Studio Code, I had installed it on Windows instead of notepad++. Because VS Code does not have a built-in code formatter or beautifier by default, I was eager to see a more powerful VS Code with extensions. Now there it is. We can find many useful extensions on Visual Studio Marketplace. Recently I was writing C/C++ code on Ubuntu and found the extension Clang-Format for beautifying C/C++ code. Let’s take a glimpse of how to make clang-format works with Visual Studio Code on Windows and Linux.

Getting Started with Clang-Format

To install an extension, we can press Ctrl+Shift+P and type in “install extension”. When all extensions listed, search for “format”, and you will see the Clang-Format: After installing the extension, you need to restart VSCode.

To format code, you can call Command Palette again with Ctrl+Shift+P, and then input “format”: The shortcut Ctrl+Shift+I is for Linux. If you want to use it on Windows, you need to use Alter+Shift+F.

If you do not have Clang-Format installed on your system, you will see the prompt:

How to Install Clang-Format on Windows

Download Clang for Windows (32-bit) or Clang for Windows (64-bit).

Install the package and add the path of %LLVM% bin to your system environment.

The shortcut Alter+Shift+F now works in Visual Studio Code for Windows.

How to Install Clang-Format on Ubuntu 14.04

There are two ways to install clang-format on Ubuntu 14.04: the stand-alone clang-format-3.4 or Clang for x86 _64 Ubuntu 14.04. The package size of stand-alone is much smaller than the full LLVM.

If you choose to install clang-format-3.4, the VS Code extension can’t work instantly. It will still prompt you that no clang-format found. Why? The installed clang-format tool is named clang-format-3.4:

To make it work, you just need to create a symlink:

Alternatively, if you download and extract the LLVM package, you will find clang-format under clang+llvm/bin:

Similarly, create a symbolic link for clang-format:
