Unlocking the Full Potential of GitHub Copilot in Visual Studio 2022

In the ever-evolving landscape of software development, staying ahead means constantly refining your tools and techniques. Recently, I embarked on upgrading my blog to .NET 8, and in doing so, I discovered some advanced, underutilized features of GitHub Copilot in Visual Studio 2022 that completely transformed my workflow.

Moving Beyond the Basics: A Deeper Dive into Copilot

Like many developers, I initially used Copilot for simple code suggestions and autocompletion. However, I soon realized that this powerful tool has much more to offer, especially when used interactively within Visual Studio. Here’s a look at some advanced capabilities that can significantly enhance your coding experience.

Named Threads and Slash Commands: Organizing and Streamlining Workflows

One of the first things I noticed was the ability to create named threads within Copilot’s chat window. This feature allows you to manage multiple streams of work simultaneously, each organized under a specific thread. Whether you’re migrating a project to a new .NET version or setting up Docker containers, having these threads keeps your tasks neatly compartmentalized.

Another standout feature is slash commands. If you’re a veteran of old-school IRC or similar platforms, you’ll appreciate the ability to use commands like /explain to get detailed explanations of selected code. This context-aware functionality ensures that you receive relevant insights based on the exact code snippet you’re working on.

Rubber Duck Debugging: A Conversational Approach to Problem-Solving

Rubber duck debugging has long been a go-to strategy for developers. The idea is simple: explain your code out loud (or to an actual rubber duck), and the process of verbalizing your thoughts often leads to solutions. With Copilot, you can take this a step further. By engaging in a back-and-forth dialogue with Copilot, you can effectively brainstorm solutions, refining your code with the tool acting as a highly responsive sounding board.

Inline Suggestions and Contextual Commands

One of the most impressive features is Copilot’s ability to provide inline suggestions. For example, while refactoring a method, you can right-click and trigger inline suggestions specific to that code block. The tool will narrow down its focus, offering guidance on just the section of code you’re working on. This level of contextual awareness is invaluable for making precise, informed changes to your codebase.

Intelligent Refactoring: Beyond Basic Renaming

Copilot also offers more than basic code refactoring. When renaming a method, for example, it doesn’t just suggest alternative names like “LoadShows” instead of “GetShows”; it also considers the broader context of your application. This feature goes beyond simple text replacement, providing intelligent insights that could lead to better code organization and readability.

Automated Test Generation and Commit Messages

Another hidden gem is Copilot’s ability to generate tests. By simply asking it to create more tests based on an existing one, you can quickly expand your test coverage. It’s not just about automation but about smart automation that understands your code’s structure and logic.

Similarly, commit message generation is a feature that can save you a lot of time. When you’ve made several changes across your codebase, Copilot can analyze the diffs and generate a comprehensive commit message that captures all the modifications, ensuring nothing is overlooked.

Error Analysis and Breakpoint Suggestions

When a test fails or an exception is thrown, Copilot steps in with error analysis. It doesn’t just identify the issue but explains why it occurred, referencing the relevant parts of your code. This transparency is crucial, as it allows you to understand the reasoning behind Copilot’s suggestions, making it easier to trust and act on its advice.

Additionally, Copilot can assist with breakpoint management, suggesting conditional breakpoints that can be incredibly useful during debugging sessions. By understanding the context of your code, it can even pre-fill conditions that align with your current line of thought.

A Friendly Partner in Coding

What became clear to me through this process is that Copilot is much more than a code completion tool. It’s a collaborative partner that understands context, provides intelligent suggestions, and helps you explore new ways to solve problems. While it’s easy to dismiss Copilot as just another autocompletion tool, doing so would mean missing out on the wealth of features that can make your development process smoother and more efficient.

In conclusion, if you’ve only been using Copilot for basic tasks, it’s time to delve deeper. Explore the chat threads, use the slash commands, and take advantage of the inline suggestions and intelligent refactoring. With these tools at your disposal, you can unlock new levels of productivity and code quality in Visual Studio 2022.
