GitHub Copilot for .NET Developers

In this article, I am going to explain how GitHub Copilot can revolutionize your .NET development process. As an AI-powered code completion tool, GitHub Copilot assists developers by suggesting code snippets, automating repetitive tasks, and improving coding efficiency. Let’s delve into the specifics of using GitHub Copilot for .NET, covering its benefits, requirements, and practical examples.

In my previous article i explained how to send DataTable to a stored procedure using C#, read request body in .NET MVC, convert JSON to DataTable using C#, and read large text files in batches using C# that you might like to read.

Problem Statement

Developing .NET applications can be time-consuming, especially when writing boilerplate code or dealing with complex logic. Developers often spend significant time on repetitive tasks, code debugging, and searching for best practices. These challenges can slow down the development process and reduce productivity.

Requirements

To get started with GitHub Copilot for .NET, you need:

1. GitHub Account: A GitHub account to access Copilot.
2. IDE Support: Visual Studio Code or Visual Studio with GitHub Copilot extension installed.
3. .NET SDK: The latest .NET SDK installed on your machine.

Benefits of GitHub Copilot for .NET Developers

1. Code Completion: GitHub Copilot provides intelligent code suggestions based on context, reducing the time spent on writing code from scratch.
2. Learning Tool: It helps developers learn new libraries and frameworks by suggesting relevant code snippets.
3. Increased Productivity: By automating repetitive tasks and boilerplate code, developers can focus on more critical aspects of development.
4. Error Reduction: It assists in reducing syntax errors and improves code quality by adhering to best practices.

Practical Examples

Example 1: Generating a Simple .NET Class

Suppose you need to create a Person class in a .NET application. With GitHub Copilot, you can generate this class quickly.

// Start typing the class definition
public class Person
{
    // GitHub Copilot suggests the properties
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int Age { get; set; }
 
    // GitHub Copilot suggests a constructor
    public Person(string firstName, string lastName, int age)
    {
        FirstName = firstName;
        LastName = lastName;
        Age = age;
    }
 
    // GitHub Copilot suggests a method to display the person's details
    public void DisplayPersonInfo()
    {
        Console.WriteLine($"Name: {FirstName} {LastName}, Age: {Age}");
    }
}

Example 2: Implementing a REST API Controller

Creating a REST API controller can be streamlined with GitHub Copilot. Here’s an example of an API controller for managing Product entities.

using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;
using System.Runtime.InteropServices;
 
// GitHub Copilot suggests the class definition
[Route("api/[controller]")]
[ApiController]
public class ProductsController : ControllerBase
{
    private readonly List<Product> _products = new List<Product>();
 
    // GitHub Copilot suggests a GET method
    [HttpGet]
    public IEnumerable<Product> Get()
    {
        return _products;
    }
 
    // GitHub Copilot suggests a POST method
    [HttpPost]
    public void Post([FromBody] Product product)
    {
        _products.Add(product);
    }
 
    // GitHub Copilot suggests a DELETE method
    [HttpDelete("{id}")]
    public void Delete(int id)
    {
        var product = _products.Find(p => p.Id == id);
        if (product != null)
        {
            _products.Remove(product);
        }
    }
}
