What is .NET?
With ASP.NET Core for web APIs and applications, .NET is a strong choice for enterprises and startups alike — especially those in the Microsoft ecosystem or building high-performance, strongly-typed backends.
Why teams choose .NET
Excellent performance — ASP.NET Core is among the fastest web frameworks
Cross-platform: runs on Windows, Linux, and macOS
Strongly-typed C# with outstanding tooling in Visual Studio
One platform for web, cloud, desktop, and mobile
Backed by Microsoft with strong enterprise support
When to use .NET
- High-performance web APIs and enterprise applications
- Teams and organizations in the Microsoft/Azure ecosystem
- Strongly-typed backends that value tooling and reliability
- Cross-platform apps sharing code across web, desktop, and mobile
Things to consider
- Historically Windows-centric, though modern .NET is fully cross-platform
- Smaller open-source community feel than JavaScript or Python
- Enterprise licensing of surrounding Microsoft tools can add cost
