Legacy modernisation · .NET Framework

Move legacy .NET Framework applications to .NET 8 in the cloud, de-risked by AI.

Web Forms, WCF and older .NET Framework code holds many businesses back from the cloud. Paradym Next reads the assemblies and configuration, recovers the business logic and rebuilds it on .NET 8 with a React or Vue 3 front end: in months, with your engineers approving every stage.

The problem

Your .NET Framework application is tied to Windows servers and old patterns.

Web Forms and WCF are not part of modern .NET, so these applications cannot move forward without being rebuilt. Meanwhile they keep running on Windows servers that cost more to host and patch.

No path forward

Web Forms and WCF have no direct equivalent in modern .NET, so upgrades mean rewriting.

Windows-bound hosting

Dependence on IIS and full Windows servers raises cloud costs and slows deployment.

Tangled code

Logic in code-behind files and shared libraries makes changes risky.

Hidden business rules

Rules are buried in code-behind event handlers, configuration transforms and stored procedures. Recovering them first is what keeps the .NET 8 version faithful to the original.

How it works

How our AI-powered modernisation engine works.

Four stages take your .NET Framework application from undocumented code to .NET 8 services with React, Vue 3 or Nuxt front ends on Azure or AWS. AI agents do the reading, mapping, writing and testing. Your engineers approve every stage.

01

Automated discovery and code parsing

Next parses your Web Forms pages, WCF services, assemblies, configuration files and SQL and extracts the business rules, data flows and integrations inside them. Every rule is traced to the code it came from, so nothing drifts in translation.

02

AI-assisted architecture blueprint

Agents map each module to clean target patterns: .NET 8 Web APIs, React, Vue 3 or Nuxt front ends in place of Web Forms, containerised services and managed cloud databases. Your architects review and approve the blueprint before any code is written.

03

Automated refactoring

From the approved blueprint, Next generates production-ready code for .NET 8 services with React, Vue 3 or Nuxt front ends on Azure or AWS. It consolidates duplicated logic and removes dead code, and your engineers review every change.

04

AI-driven regression testing and validation

Generated test suites run the old and new systems on the same inputs, validating 99% functional equivalence before deployment. Any difference goes to your team to resolve.

Value acceleration

What AI acceleration changes.

Compared with a standard manual migration of your .NET Framework application.

Up to 40%

less development effort than a standard manual migration.

3–4x

faster upgrade and migration cycles.

Up to 60%

lower operational and cloud infrastructure overhead.

Risk and accuracy

AI does the heavy lifting. Your engineers make the decisions.

For a CTO or CIO, the risk in a rewrite is not speed but correctness. Human review is built into every stage, so AI output never reaches production unchecked.

Traced to source

Every extracted rule and generated module links back to the .NET Framework code it came from, so reviewers can check it line by line.

Human approval gates

Discovery, blueprint, code and release each need sign-off from your people. Nothing moves forward on AI output alone.

Equivalence testing

Old and new systems run the same test cases side by side, validated to 99% functional equivalence before deployment.

Governed AI

You choose which models are used and where they run, and every agent action is recorded for audit.
