.Net
Your .NET Framework application still runs the business, but Microsoft stopped investing in it, the shop that built it may be gone, and every new feature takes longer than it should. Technijian's Orange County team builds, migrates, and modernizes .NET applications onto .NET 8, with Clean Architecture and CI/CD from day one.
Sound Familiar?
- Your core business application — the ERP, CRM, internal portal, or customer-facing platform that generates revenue — was built on .NET Framework 4.6 or 4.8 five to twelve years ago, and Microsoft put it in permanent maintenance mode three years ago: security patches only, no path to Linux or containers.
- You paid a development agency to build a custom .NET application, and then they pivoted to AI consulting, the lead developer left, or the company folded — leaving you with a production app, no documentation, no automated tests, and NuGet packages nobody has touched in years.
- Your backend runs on WCF services that Microsoft has deprecated and will not port to modern .NET, and the move to REST APIs or gRPC has been 'planned' for two years without anything actually shipping.
- Your team still deploys by right-click Publish, releases take 45 seconds, the application crashes under 200 concurrent users, and features ship once a month instead of every sprint.
- Senior engineers don't want to join a team maintaining legacy .NET Framework in 2026, and every feature takes three times longer than it should because your team is fighting the framework instead of building product.
The Typical Approach vs. Technijian
❌ Typical Provider
Most dev shops offer one of two things: a full rewrite that takes months of discovery before a single feature ships, or a patch job that keeps the .NET Framework application alive without touching the underlying platform, the end-of-life WCF services, or the missing tests. Either way, you're stuck waiting or you're stuck stalled.
✓ The Technijian Way
Technijian treats it as a phased migration: WCF services get replaced incrementally with ASP.NET Core Web API or gRPC endpoints while your existing application keeps running, the codebase moves to .NET 8 with Clean Architecture, and CI/CD is in place from day one — so you get 2-week sprint cycles shipping real progress instead of a stalled rewrite.
What’s Included
- .NET Framework to .NET 8 Migration — Move your .NET Framework 4.x application onto .NET 8 — our standard for all new development — so it can run on Linux and in containers, exit maintenance-mode-only support, and stop costing 2-3x more to host than it needs to.
- Legacy Codebase Inheritance & Stabilization — Take over an undocumented application left behind by a dev shop that's gone dark — no automated tests, no documentation, a 'copy files and pray' deployment process — and stabilize it before any new features get built.
- WCF to REST API / gRPC Migration — Replace WCF service contracts, data contracts, bindings, and behaviors incrementally with ASP.NET Core Web API or gRPC endpoints, keeping your existing application running throughout the migration.
- Blazor & React Frontend Modernization — Rebuild aging Web Forms or MVC front ends in Blazor or React on top of the modernized .NET backend, built to Clean Architecture principles.
- Azure Cloud-Native Deployment & CI/CD — Move off right-click Publish and onto Azure cloud-native infrastructure with CI/CD pipelines running from day one, delivered in 2-week sprint cycles so features ship continuously instead of once a month.
Why Technijian
Technijian has built, migrated, or modernized 200+ .NET applications, and .NET 8 — the current LTS release — is our standard for all new development, not whatever version happens to be newest. That standard is what makes a 50% average performance gain and 60% less memory use realistic outcomes of a migration rather than a like-for-like port that just moves the same problems onto newer infrastructure. We work in 2-week sprint cycles with CI/CD in place from day one, so a WCF-to-REST migration or a legacy codebase inheritance ships in increments you can see, not a multi-month rewrite with nothing to show until the end.
Industries We Serve
Technijian modernizes .NET applications for organizations running revenue-generating platforms — ERPs, CRMs, internal portals, and customer-facing systems — that were built on .NET Framework years ago and now need to run on current, supportable infrastructure.
