.NET Framework to modern .NET.
Move legacy .NET Framework applications to current .NET for better speed, security and hosting options, without disrupting the business.
Migrating from .NET Framework to modern .NET (such as .NET 8) involves checking compatibility, upgrading libraries, moving projects in stages and replacing Windows-only parts. The result runs faster, receives current security updates and can be hosted on Linux and in the cloud.
Sound familiar?
- You are stuck on .NET Framework 4.x or older.
- The app only runs on Windows servers you want to retire.
- Libraries have no versions for your current setup.
- Hosting costs are high because of licensing.
How we handle it.
Four clear steps, with you informed at each one.
Assess compatibility
Run analysis tools and review unsupported APIs and packages.
Upgrade in layers
Move shared libraries first, then services, then the web layer.
Replace blockers
Rewrite Windows-only components such as legacy UI or WCF where needed.
Test and deploy
Verify behaviour, performance and deployment, then switch over.
Mistakes to avoid.
Upgrading everything at once
Layered upgrades are easier to test.
Ignoring third-party libraries
Check each dependency for a supported version early.
Skipping performance tests
Compare before and after, so you can prove the gain.
Common questions.
Can .NET Framework apps run on Linux after migration?
Modern .NET runs on Linux, macOS and Windows, which opens up cheaper hosting.
What about WCF or Web Forms?
These have no direct equivalent and are replaced with modern approaches such as APIs and Blazor or a JavaScript frontend.
Is it a full rewrite?
Often most code carries over. The parts that depend on removed features are rebuilt.
