If you’re a developer using Visual Studio 2022, you’ve probably heard about GitHub Copilot. It’s an AI-powered coding assistant that helps you write code faster, minimize repetitive tasks, and even suggest solutions to complex problems. But how exactly can it improve your productivity?
In this article, we’ll explore the top ways GitHub Copilot can enhance your workflow in Visual Studio 2022, helping you write better code in less time.
1. Faster Code Completion and Suggestions
One of the most obvious benefits of GitHub Copilot is its autocomplete capabilities. Instead of typing out entire functions or classes, Copilot can predict what you’re about to write and offer real-time suggestions.
How it helps:
- Reduces keystrokes by suggesting entire lines or blocks of code.
- Understands context, predicting variable names and function structures based on your existing code.
- Speeds up repetitive tasks, such as writing boilerplate code, getter/setter methods, or database queries.
For example, if you’re writing a function to fetch data from an API, Copilot might generate:
public async Task<List<User>> GetUsersAsync()
{
using (HttpClient client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync("https://microsoft.graphapi.example/users");
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<List<User>>(responseBody);
}
}
Instead of writing all of this from scratch, Copilot suggests it based on your method name and context. That’s a huge time saver!
2. Helps with Learning and Exploring New APIs
Whether you’re working with a new framework, library, or API, Copilot can help you discover best practices and learn how to use unfamiliar code structures.
How it helps:
- Auto-generates API calls based on method names.
- Suggests the correct syntax for new libraries.
- Reduces time spent searching Stack Overflow for examples.
Let’s say you’re new to Entity Framework Core and need to fetch data from a database. Instead of Googling examples, just start typing, and Copilot will generate:
public async Task<List<Customer>> GetActorsAsync()
{
using (var context = new AppDbContext())
{
return await context.Actors.ToListAsync();
}
}
This is especially helpful for junior developers or when learning new technologies on the go.
3. Automates Boilerplate and Repetitive Code
We all hate writing the same repetitive code — whether it’s logging, exception handling, or writing test cases. GitHub Copilot takes care of that by automatically generating common patterns.
How it helps:
- Speeds up unit test writing, suggesting test cases based on existing methods.
- Generates logging and exception handling blocks.
- Handles repetitive tasks like constructors and DTOs.
For instance, if you have a method that needs structured logging:
public async Task ProcessOrderAsync(Order order)
{
// Business logic here
}
//Log order Id and add error handling.
public async Task ProcessOrderAsync(Order order)
{
try
{
_logger.LogInformation("Processing order {OrderId}", order.Id);
// Business logic here
}
catch (Exception ex)
{
_logger.LogError(ex, "Error processing order {OrderId}", order.Id);
throw;
}
}
Copilot can auto-generate logging and error handling, saving you from writing it manually.
4. Enhances Code Readability and Best Practices
Writing readable, maintainable code is crucial, but we often fall into bad habits — using poor variable names, skipping comments, or not following best practices.
How it helps:
- Suggests meaningful variable and function names.
- Adds comments automatically for better readability.
- Follows coding standards based on context and existing code.
For example, if you write a complex function, Copilot may suggest meaningful inline comments, improving readability for your future self and teammates.
5. Assists in Writing Unit Tests Faster
Testing is essential, but writing unit tests can be time-consuming. Copilot can generate test cases based on your existing functions, reducing the manual effort needed.
How it helps:
- Creates unit test templates for methods automatically.
- Suggests assertions based on function outputs.
- Speeds up Test-Driven Development (TDD).
For example, if you have a method:
public int Add(int a, int b)
{
return a + b;
}
Copilot can generate the corresponding unit test:
[Test]
public void Add_ShouldReturnCorrectSum()
{
var result = Add(2, 3);
Assert.AreEqual(5, result);
}
This speeds up test coverage and ensures fewer bugs in production.
6. Boosts Collaboration with Teams
If you’re working on a team, Copilot helps by:
- Providing consistent coding patterns across team members.
- Encouraging best practices without extensive documentation.
- Reducing the need for pair programming on simple tasks.
Instead of waiting for a senior developer to review and suggest improvements, Copilot helps you write cleaner code upfront, leading to fewer review cycles.
7. Supports Multiple Languages and Frameworks
If you switch between different programming languages (C#, JavaScript, Python, etc.), Copilot adapts to each language’s syntax and best practices.
How it helps:
- Works across multiple frameworks like .NET, Angular, React, and Python.
- Understands project context, whether frontend, backend, or full stack.
- Saves time when switching between languages.
For example, if you’re building an ASP.NET API but need to write some JavaScript for the frontend, Copilot helps you transition smoothly without looking up syntax differences.
Final Thoughts: Is GitHub Copilot Worth Using?
Absolutely! GitHub Copilot is like having an AI-powered coding assistant that helps you write code faster, reduce errors, and automate tedious tasks.
While Copilot isn’t perfect (it sometimes suggests incorrect or inefficient code), when used wisely, it significantly boosts productivity. If you’re using Visual Studio 2022, integrating Copilot into your workflow is a game-changer!
