Artificial Intelligence in a C# Developer's Arsenal: From Autocomplete to Code Generation

Modern development on the .NET platform increasingly relies on artificial intelligence tools. It is no longer enough to simply write code manually — AI assistants save hours of work, help avoid bugs, and speed up refactoring. We have gathered the key AI solutions that every C# developer should try.

1. GitHub Copilot — The Universal Partner

The market leader in AI code assistants. It works in Visual Studio and VS Code. Copilot analyzes the context and suggests entire functions, methods, and even unit tests. For C#, it is especially useful when working with LINQ, asynchronous operations (async/await), and Entity Framework.

Pros: deep integration, understands complex patterns, supports a chat interface.
Cons: paid subscription ($10/month), sometimes generates redundant code.

2. Visual Studio IntelliCode — AI at the Service of Intellisense

A free extension from Microsoft. IntelliCode does not replace Copilot, but significantly improves standard autocomplete. It ranks suggested options based on thousands of popular projects from GitHub. For C#, this means more accurate suggestions for collections, strings, and .NET APIs.

Pros: free, does not require a powerful internet connection, improves typing speed.
Cons: cannot generate code blocks, only suggests lines.

3. ReSharper with AI Extension (JetBrains)

The legendary code analyzer has received AI features. JetBrains added the ability to get error explanations, one-click refactoring, and XML documentation generation. For C#, this is a lifesaver when working with legacy code and complex generic structures.

Pros: powerful refactoring, deep code analysis, SOLID hints.
Cons: paid (from $149/year), heavy for weak PCs.

4. ChatGPT and Its Integrations

OpenAI ChatGPT (especially the GPT-4 version) is actively used for writing C# scripts, converting code from other languages, and debugging. There are extensions for Visual Studio (e.g., ChatGPT for .NET) that allow you to ask questions directly in the IDE.

Pros: versatility, understanding of natural language, free access (with limitations).
Cons: no direct integration with the compiler, possible hallucinations.

5. Codeium — A Free Alternative to Copilot

A rapidly growing startup offering a free AI assistant for individual developers. It supports C#, ASP.NET Core, and Blazor. It handles repetitive tasks well: writing DTOs, mapping, simple controllers.
