Avion Technology Builds and Modernizes .NET Applications That Are Built to Last
From a new enterprise application built on modern ASP.NET Core, to a legacy .NET Framework system that’s been running your business for a decade and finally needs to move forward, Avion Technology designs, builds, and modernizes .NET applications with the reliability and long-term thinking .NET was built for.
We treat .NET Framework migration as a real specialty, not an afterthought. Modern ASP.NET Core for new builds, careful, staged migration for legacy systems built by people who understand both sides of the .NET ecosystem, not just whichever one is currently trendy.
.NET Services Avion Technology Delivers
We provide end-to-end .NET services — from new application development through legacy modernization, API development, and long-term support.
Custom .NET Application Development
What it is: Full applications built from the ground up on modern ASP.NET Core to your specification.
Benefits: A product built on solid, enterprise-grade architecture from day one, not shortcuts you’ll pay for later.
Ideal for: Businesses building a new enterprise application or internal system.
Expected outcome: A production-ready .NET application built around your requirements.
.NET Framework to .NET Core/Modern .NET Migration
What it is: A staged migration plan and execution moving your application from legacy .NET Framework to current, cross-platform .NET.
Benefits: Off unsupported infrastructure and onto a modern, actively developed platform, without a risky big-bang rewrite.
Ideal for: Businesses running business-critical applications on aging .NET Framework.
Expected outcome: A working application incrementally migrated to modern .NET.
Legacy .NET Modernization & Refactoring
What it is: Refactoring and modernizing an aging or poorly structured .NET codebase,
whether or not a full framework migration is needed.
Benefits: A faster, safer, easier-to-extend application without necessarily a full rewrite.
Ideal for: Businesses with a .NET application that’s become difficult to maintain.
Expected outcome: A cleaned-up,
modernized codebase your team can build on confidently.
ASP.NET Core API Development
What it is: API-only .NET backends built to serve modern frontends, mobile apps, or third- party integrations.
Benefits: A clean, fast, cross-platform backend decoupled from any specific frontend.
Ideal for: Businesses building or already running a modern web or mobile frontend.
Expected outcome: A well-documented, performant .NET API.
Blazor Development

Ideal for: .NET teams wanting rich
interactivity without a separate JavaScript framework.
Expected outcome: A responsive,
interactive application built with Blazor.
Performance Optimization
What it is: Diagnosing and fixing slow queries, inefficient Entity Framework usage, caching
gaps, and background processing issues.
Benefits: A faster, more reliable application under real production load.
Ideal for: Applications experiencing slowdowns as data and traffic grow.
Expected outcome: Measurably faster response times and more reliable processing.
Database Design & Entity Framework Optimization
What it is: Schema design, indexing strategy, and Entity Framework Core query optimization.
Benefits: A data layer that stays fast and correct as your application scales.
Ideal for: Applications with complex data models or growing datasets.
Expected outcome: A well-structured, properly indexed database that performs at scale.
Azure Cloud Integration
What it is: Deploying and integrating .NET applications with Azure services for hosting, storage, and cloud-native capabilities.
Benefits: A cloud deployment that takes advantage of .NET’s native, deep Azure integration.
Ideal for: Businesses running or planning to run .NET workloads on Azure.
Expected outcome: A properly deployed, Azure-integrated .NET application.
.NET Microservices Development
What it is: Architecting and building .NET applications as microservices where genuinely warranted.
Benefits: Independent scaling and deployment for the parts of your system that need it.
Ideal for: Larger .NET systems with real scaling or team-autonomy requirements.
Expected outcome: A properly bounded, resilient microservices architecture built on .NET.
Third-Party & AI Integration
What it is: Connecting your .NET application to payment gateways, CRMs, analytics, and AI/LLM services.
Benefits: A connected, capable application where data and functionality flow automatically.
Ideal for: Applications that rely on external services or AI-powered features.
Expected outcome: Seamless, well-tested integrations.
Code Audit & Technical Due Diligence
What it is: A structured review of an existing .NET codebase’s architecture, test coverage, and technical debt, including framework version risk.
Benefits: A clear, prioritized picture
of what’s solid and what needs attention — useful before investing, hiring, or planning a modernization roadmap.
Ideal for: Businesses inheriting a codebase, evaluating an acquisition, or planning a modernization push.
Expected outcome: A detailed audit report with prioritized recommendations.
.NET Maintenance & Support
What it is: Ongoing development, bug fixes, dependency updates, and monitoring after launch or migration.
Benefits: An application that stays secure, current, and reliable, with a partner who knows it well.
Ideal for: Businesses that want continuous improvement and peace of mind long-term.
Expected outcome: A well-maintained, continuously evolving .NET application.
Our Implementation Process
How Avion Technology Will Build Your React Application
Phases
What happens
Discovery & Assessment
We learn your goals and requirements — and if you have
existing code, including legacy .NET Framework, we review what’s there.
Planning & Architecture
We define features, data model, scope, and the right
technical architecture, including a migration plan if relevant.
Development
We build with clean, tested, idiomatic C# and .NET code from the start.
Migration Execution
If modernizing, we migrate incrementally, validating
functionality at each stage.
Testing
We build meaningful test coverage and validate the application against real scenarios.
Deployment & Launch
We set up CI/CD and deploy with monitoring in place from
day one.
Support & Growth
We maintain, optimize, and extend your application as your
needs evolve.

FAQs
Your .NET Questions, Answered
.NET Framework is legacy technology receiving limited updates, is Windows-only, and increasingly harder to hire for. Modern .NET is cross-platform, actively developed, generally faster, and gives you access to a much larger, more current talent pool.
It can be if done carelessly, but we plan and execute migrations in stages, validating functionality at each step, which significantly reduces the risk compared to a disruptive, all-at-once rewrite.
In most cases, yes. We assess your existing codebase and migrate incrementally, preserving what’s working and modernizing what needs it, rather than starting from zero unnecessarily.
It depends heavily on the size and complexity of your existing application and its dependencies. We provide a realistic timeline after a thorough assessment, since rushing this specific type of project tends to create more risk than it saves.
Yes. We build new enterprise applications on current ASP.NET Core with the architecture and testing discipline built in from day one.
Blazor lets you build interactive web UI using C# instead of JavaScript, which can reduce context-switching for .NET-focused teams. We use it when it’s the right fit and recommend a JavaScript frontend when that better suits your requirements.
Yes. We regularly inherit existing .NET applications, including legacy .NET Framework systems, audit the codebase, and take over ongoing development and maintenance.
Usually, yes. Most performance problems come from specific issues, like inefficient Entity Framework queries or missing indexes, that we can diagnose and fix without a full rewrite.
Yes. We build meaningful test coverage using xUnit or NUnit as a core part of development, not an afterthought, so your team can deploy with confidence.
Yes. We build API-only ASP.NET Core applications designed to serve mobile apps, single-page applications, or other clients cleanly.
