The Legacy .NET Problem
Hundreds of enterprise and mid-market applications still run on .NET Framework 4.x, creating mounting risks.

Security Vulnerabilities

.NET Framework receives only security patches from Microsoft. No new features, no improvements. Aging dependencies create an expanding attack surface that puts your business at risk.

Performance Bottlenecks

Modern .NET delivers 3-10x better throughput and lower memory usage. Legacy apps waste cloud infrastructure spend and deliver subpar user experiences.

Talent Crisis

Fewer developers want to work on legacy .NET Framework. Recruiting and retaining talent for aging technology stacks is becoming prohibitively expensive.

Innovation Roadblock

Cannot leverage AI services, cloud-native architectures, or the latest SDKs and libraries. Your competitors on modern stacks are moving faster.
