Get off IdentityServer4 and legacy .NET — safely

Five senior .NET engineers who migrate IdentityServer4 to Duende and .NET Framework to .NET 10. Fixed-scope packages, with AI doing the mechanical work under engineering guardrails that build- and test-gate every change.

Two migrations we know cold

Both start with an $80 working session. If you go ahead with the package, the session fee counts toward it.

Legacy .NET → .NET 10

Still on WebForms or .NET Framework 4.x? .NET 8 and 9 leave support on November 10, 2026, too.

A Readiness Assessment inventories your solution, maps every blocker (WCF, WebForms controls, EF6 patterns, third-party packages), and gives you a sequenced, sprint-level migration plan you can run with us or any team.

Package
Readiness Assessment, one 2-week sprint — from $4,800
Legacy .NET modernization

Not a migration? We take general .NET work too — by the hour, by the sprint, or end-to-end.

How a migration starts

Four steps from first contact to a written plan. Not sure we're a fit yet? Start with a free 45-minute call instead.

1

Send us your setup

Versions, project count, key packages, and what hurts. A rough shape is enough — the booking form takes two minutes.

2

We prep before the call

A pre-assessment email digs into your specifics, so session time isn't spent explaining the basics.

3

60-minute working session

Zoom or Teams. Blocker triage, sequencing, live debugging — whatever your migration needs first. $80.

4

Written summary in 24 hours

The main blockers and a recommended path. If a package fits, you get a fixed-scope proposal and the $80 counts toward it.

A big-bang rewrite

  • Months of work before anything ships
  • Business logic re-derived from memory instead of verified
  • One cutover with no rollback plan
  • AI-generated code nobody checked against the old behavior

An incremental migration with us

  • Strangler-fig sequencing: converted sections ship continuously
  • Multi-targeting, so you keep shipping mid-migration
  • Parity tests on behavior-critical paths
  • AI does the mechanical work; every change is build- and test-gated
  • A deployment and rollback plan before cutover

Transparent pricing

No hidden fees. No long-term contracts. Pick the engagement that fits.

Frequently asked questions

What CTOs and CEOs ask before working with us

How does the sprint-based model work?

We work in 2-week sprints. Each sprint starts with priority alignment, includes weekly check-ins, and ends with a tangible deliverable — a new feature, a system integration, a performance fix. No long-term contracts. Pause or cancel anytime. You only pay for what you need.

How much does it cost to hire a .NET development company?

It depends on the engagement. Our 1-hour consulting is $80/session. Sprint-based development starts from $4,800 per 2-week sprint. For new SaaS projects, we have a production-ready template with 23 built-in features — projects start from $20,000 instead of the typical $50K–$150K for an MVP.

What makes your SaaS template different from boilerplates?

Most boilerplates give you auth, maybe billing, and a landing page. Our template ships with 5 fully connected applications — user-facing app, API, admin dashboard, status page, and documentation site — plus support ticketing, real-time notifications, file storage, a complete observability stack, email system with 15 templates, and blue-green deployment pipelines. It's not a starter kit. It's a production-ready product.

Can you work alongside our existing team?

Yes. Our sprint model is built for this. We plug into your existing workflows, tools, and codebase. Strict NDAs protect your IP, and we handle our own infrastructure and QA. Think of it as adding senior .NET specialists to your team without the hiring overhead.

How fast can you deliver an MVP?

With our SaaS template, the 23 shared features — auth, billing, support, monitoring, admin — are already built. Your team only writes the business-specific logic. What typically takes 4–6 months can ship in weeks. Re-platforming our own template cut its infrastructure cost by 94% and compute time by 92%; client migrations typically land at 60–90% cost reduction.

Do I own the source code?

Yes. 100%. All custom code and IP belong to you. It's in the contract.

Is .NET still a good choice in 2026?

The .NET development market hit $10.5 billion in 2024 and is projected to reach $25.7 billion by 2033. .NET consistently ranks among the top-performing frameworks in benchmarks, runs cross-platform, and powers enterprise applications at companies like Dekra, Glass Lewis, and Betsson — all clients of ours.
