Dot Net Development Company ASP.NET Core. Build Your Platform. Then Your Mobile App.
Partner with a dot net development company that builds high-performance ASP.NET Core web applications, enterprise software, and REST APIs — then extends them to iOS and Android mobile apps on the same backend. Fixed price. Direct C# engineer access. Trusted by clients across USA, UK, Canada and India. Our AI-powered development pipeline delivers every .NET project faster and with fewer defects.
A Dot Net Development Company That Builds Platforms and Mobile Apps on One Backend
Most businesses that invest in a .NET web platform eventually hit the same wall: the platform works, but their customers need a mobile app — and the original .NET vendor does not do mobile. That forces a second agency, a second codebase, and a backend architecture designed by one team and consumed by another. The result is duplicated business logic, mismatched API contracts, and two vendors pointing at each other when something breaks.
Our team builds the ASP.NET Core backend and the mobile app development layer on top of it — same team, same architecture decisions, same codebase ownership. Whether you are starting with a web platform and planning mobile later, or need both simultaneously, the backend is designed from day one to serve both. Our AI-powered development pipeline integrates Azure OpenAI Service and ML.NET as clean service layers — not afterthoughts — ready to serve both your web and mobile clients from a single AI layer.
Every .NET codebase we deliver follows clean architecture — separated into API, business logic, and data access layers — with full test coverage using xUnit, dependency injection via Microsoft DI, and CI/CD pipelines on Azure DevOps or GitHub Actions. ASP.NET Core APIs are optimised for sub-100ms response times using Entity Framework Core with compiled queries, Redis caching, and async/await throughout. The same high-performance backend serves web and mobile clients simultaneously without separate deployments.

What Our We Deliver Builds for You
End-to-end ASP.NET Core development services — from custom web applications and enterprise software to REST APIs and AI-powered .NET backends. Fixed price. Full source code ownership. Mobile extension ready.
.NET Development Tools We Work With
Every .NET project is built with the Microsoft-recommended stack — ASP.NET Core, Entity Framework Core, and Azure or AWS for hosting. Tested, documented, and handed over with full source code.
Real .NET Challenges.
Every project carries risks — poor UX, missed deadlines, underperforming results. Here is how we eliminate each one.
How We Deliver .NET Projects
A six-stage delivery process designed for overseas clients — every milestone is visible, every sprint produces a deployable build, and every invoice is tied to a deliverable. The same discipline we apply whether building your <a href="/mobile-app-development-company-india/" class="content-link">.NET web platform or mobile app</a>. No black-box development. No surprises at launch.
Discovery & Architecture Planning
We begin with a structured discovery call to understand your .NET requirements, existing infrastructure, integration points, and business goals. We design the solution architecture — web layer, API layer, database schema, and third-party integrations — and document the complete scope before any development begins.
UI/UX Design & API Contract Design
Every .NET web application screen is designed and approved in Figma before development begins. API contracts are documented — endpoints, request/response schemas, authentication model — and agreed before backend development starts. No surprises when frontend and backend teams integrate.
Fixed-Price Proposal
A fixed-price proposal covers the complete .NET scope — ASP.NET Core backend, frontend, database, third-party integrations, deployment configuration, and documentation. One price. Complete deliverable. No hourly billing. No scope creep on agreed features.
ASP.NET Core Development
.NET development runs in two-week sprints using C# with ASP.NET Core, Entity Framework Core, and your chosen database. You receive a deployable build on staging at the end of every sprint — fully testable — so you see real progress across frontend, backend, and API throughout the project.
QA — Automated and Manual Testing
Every .NET build is tested with automated unit tests, integration tests, and API contract tests before staging deployment. Manual QA covers UI, cross-browser compatibility, performance under load, and security vulnerability scanning. No build goes to you without passing all test suites.
Deployment, Launch & Mobile Extension
We manage complete deployment to Azure, AWS, or your chosen infrastructure. Post-launch support is included for 60 days. And when your business is ready to extend the platform to mobile users — our team builds the iOS and Android mobile app directly on top of your existing .NET backend.
Industry-Specific .NET Development
We deliver AI solutions for .NET applications and enterprise platforms across the industries where Microsoft ecosystem depth, C# type safety, and Azure cloud integration deliver the most robust and scalable outcomes — energy, healthcare, and automotive.
What Sets Our .NET Development Apart
Businesses choose us because of how we work — not just what we build.
for Enterprise Backends vs Node.js vs Python / Django — Which Is Right for You?
Choosing the right backend for your enterprise platform. How ASP.NET Core compares against Node.js and Python for web applications, REST APIs, and enterprise software — across the criteria that matter most to business owners.

Every .NET project at AZRIVA is fixed price — scoped completely before development begins. Pricing depends on scope, integration complexity, and platform scale. All tiers include full source code ownership.
All pricing is fixed — the number in your proposal is the number on your invoice. Clients who extend their .NET platform to mobile app development receive the same fixed-price model for the mobile project. VAT/GST applicable for Indian clients.

Complete .NET scope defined and priced before development begins. Web application, REST API, admin panel, integrations, and deployment — one fixed price. No hourly billing. No scope creep on agreed features. The same fixed-price model extends to mobile app development when you are ready.
