New IDE for C# (.NET): Feature Overview and First Impressions

New IDE for C# (.NET): First Look — What Does It Offer Developers?

The market for development tools on the .NET platform continues to actively evolve. A new integrated development environment (IDE) has recently emerged, focused exclusively on C# and the .NET ecosystem. In this article, we will examine its key features, performance, and first impressions from using it.

Key Features of the New IDE

The developers position the product as a lightweight yet powerful alternative to heavyweight solutions. Here is what stands out at first glance:

• Lightning-fast startup and low memory consumption: The IDE starts in literally 2–3 seconds, consuming about 200–300 MB of RAM at idle. This is especially important for those working on machines with limited resources.
• Deep integration with .NET 8 and 9: Full support for the latest framework versions, including AOT compilation, Source Generators, and Hot Reload for web and desktop projects.
• Smart IntelliSense based on ML: Code suggestions are not just static — the environment analyzes the project context and offers the most relevant method and class options, speeding up code writing by 20–30%.
• Built-in debugger with LINQ visualization: The debugger allows you to view LINQ query results in real time without leaving debug mode. This is a real find for those who frequently work with collections and databases.
• Refactoring "on the fly": Over 40 automatic refactorings are available — from renaming across the entire call chain to extracting interfaces and optimizing async/await.

Performance and Compatibility

Initial tests show that the environment is practically on par with Visual Studio in build speed for complex solutions, but wins in interface responsiveness. Developers note stable operation with solutions of up to 500 projects.

The IDE is fully compatible with .csproj and .sln project formats and supports the NuGet package manager out of the box. For team collaboration, integration with Git (pull requests, blame, visual branch comparison) is provided.

First Impression and Conclusions

After several hours of working with the new IDE, it can be confidently said: this is not just "another environment," but a well-thought-out tool that fills the niche between the bulky Visual Studio and overly minimalist editors like VS Code. Working with large solutions was especially pleasing — no lag when opening files or switching between tabs.

On the downside: there is currently no built-in memory profiler or tools for working with Docker (only via CLI). However, the developers promise to add them in upcoming updates.

Verdict: if you are looking for a fast, modern, and specialized environment for C# and .NET — this IDE definitely deserves attention. It is suitable for both educational projects and industrial development.
