Shrinking talent pool
Fewer engineers want to work in .NET Framework, WebForms, or classic ASP — hiring and retention get harder every year.
The Problem
Legacy .NET Framework Is Quietly Becoming a Liability
The application still works — but every year it gets harder to staff, harder to secure, and harder to extend.
Security & compliance risk
.NET Framework no longer receives new feature investment from Microsoft, leaving older apps increasingly exposed as standards move on.
Locked to Windows Server & IIS
You can't take advantage of cross-platform hosting, containers, or modern cloud pricing while the app is tied to legacy infrastructure.
Hard to extend
Adding new features, APIs, or integrations takes longer every year as the framework falls further behind the modern .NET ecosystem.
How We Work
Assess First. Then Migrate, In Sprints — Not a Big-Bang Rewrite.
Fixed-Price Code Assessment
We review your current .NET Framework application — architecture, dependencies, data access, and risk areas — and deliver a clear migration plan with scope, approach, and timeline before any migration work begins.
Migration in Sprints
We migrate the application in incremental, reviewable sprints rather than a single big-bang rewrite, so your team can validate progress and your business keeps running throughout.
Ongoing Support
After go-live we stay on to monitor, fix and keep the application current on supported .NET versions, and can add AI features and workflow automation once the new foundation is in place.
Step 1: The Code Assessment
Know Exactly What Your Migration Will Take Before You Commit to It
A fixed-price, fixed-scope review of your application. You keep every deliverable, whether or not you migrate with us.
What you get
- Architecture & dependency auditEvery project, NuGet package and third-party library mapped and checked for .NET Core / .NET 8+ compatibility.
- Risk registerThe blockers — WebForms pages, WCF services, Windows-only APIs, data access — ranked by effort and business risk.
- Migration roadmapA sprint-by-sprint plan for moving the application incrementally while it stays live.
- Cost & timeline estimateA fixed scope and price range for the full migration, so you can budget and get sign-off.
- Walkthrough with your teamA live session to review findings with your engineers and answer their questions.
Case Studies
Legacy .NET Work We've Delivered
Real projects, described as they happened. Client names are kept confidential.
ASP.NET (.NET Framework 4.8) to ASP.NET Core Migration
IT services company · 51–200 employees · Jul 2025 – Jan 2026
The situation
The client's web application ran on ASP.NET and .NET Framework 4.8. They needed it moved to ASP.NET Core while their own team kept working, and the legacy code had to be understood and documented first.
What we did
- Analyzed and documented the legacy ASP.NET code before changing it
- Migrated Web API actions, data models and Razor views to ASP.NET Core
- Worked in two-week sprints, with every task tracked in Jira against acceptance criteria
- Shipped every change through pull request → test environment → QA notes
Outcome
- Delivered sprint by sprint over six months
- Minimal production bugs reported
- Rated 4.5 / 5 overall and 5.0 / 5 for cost

What we did
- Worked across the legacy MVC 5, WinForms and Windows Services parts alongside newer .NET Core and Blazor modules
- Built structured clinical documentation, including an interactive spine diagram for vertebra-level diagnosis
- Added secure document storage on Azure Blob Storage, PDF generation and e-signatures
- Delivered patient and client portals with full audit trails
Outcome
- Structured diagnosis records instead of free-text notes
- Clinical documents stored securely in the cloud
- Legacy and modern .NET running side by side in one product

Production Audit of a .NET 8 Multi-Tenant SaaS
AI voice agent platform for US small businesses
The situation
A production .NET 8 platform serving many customer accounts (tenants) and handling live phone calls needed its security and tenant isolation reviewed.
What we did
- Audited authentication and authorization across the API
- Checked tenant isolation, so one customer can never see another's data
- Reviewed webhook handling for tampering and replay risks
- Fixed the issues found, in the production codebase
Outcome
- Completed production security audit
- Auth, tenancy and webhook integrity issues fixed
- The same audit approach we use in our code assessments
