Why .NET Wins for Enterprise (Based on 350+ Projects)

Performance Reality: 2-3x Faster Than Alternatives

.NET Core delivers throughput comparable to Node.js and Go. In our benchmarks, .NET APIs consistently handle 100,000+ requests per second on standard hardware. Real-world application: payment processing system handling 50,000 transactions per hour with sub-100ms response times.

Development Speed: 40% Faster Than Java

Entity Framework eliminates weeks of database coding. ASP.NET Core MVC provides built-in authentication, routing, and validation. Based on actual project data across 350+ applications, .NET projects average 40% shorter timelines than equivalent Java implementations.

Microsoft Ecosystem Integration

Seamless integration with Azure (hosting), Active Directory (authentication), Office 365 (document processing), SQL Server (database), and SharePoint (collaboration). For organizations already using Microsoft products, .NET integration saves 30-50 hours of development time per project.

Long-Term Support: 3-Year LTS Cycles

.NET follows predictable release cycles with 3-year Long-Term Support. Applications built on .NET 6 (November 2021) receive support until November 2024. This stability matters for enterprise applications requiring 10+ year lifespans.

Cross-Platform Freedom Since 2016

.NET Core runs identically on Windows, Linux, and macOS. Host on any cloud (Azure, AWS, Google Cloud) or on-premises servers. Real deployment: manufacturing application running on Ubuntu servers, reducing licensing costs by $50,000 annually.
