Exploring Features of GitHub Copilot in Visual Studio

• Natural language support for programming languages – GitHub Copilot’s artificial intelligence understands & processes natural language to provide code suggestions, making it easier to translate ideas into actual code efficiently.
• Autocomplete-style suggestions – Offers suggestions for entire functions, methods, and even code snippets, reducing manual coding, thereby saving time and increasing productivity.
• Personalized suggestions based on context – Provides suggestions on the context of a function, variable name, and even keyboard shortcut, helping you complete the code faster.
• Ability to analyze billions of lines of code at once – GitHub Copilot has been trained on vast amounts of codebases, therefore, it can analyze code to provide relevant suggestions.
• Accessible from the left-hand side panel – You can click the GitHub Copilot’s icon and select Open Copilot to get it on the left side, ensuring an integrated and seamless experience on Visual Studio.
• Neural network – The tool uses a neural network, a variant of the Generative Pre-trained Transformer (GPT) architecture, to generate intelligent and accurate code completion suggestions.
• Add comments or structured blocks of code – It suggests relevant code and also helps add comments and structured blocks faster, which improves code readability and manageability.
• Boilerplate code generation – When you start a new function, method, or class, GitHub Copilot can generate the initial boilerplate code, which saves you time and helps you focus on writing the core logic of a program.

The seamless integration of GitHub Copilot within Visual Studio can help you perform repetitive tasks faster and more efficiently. You can add the GitHub Copilot for Business using the same steps. To know more, read this guide.
