Real .NET Challenges. Real Solutions.

Every business building a .NET platform faces the same three obstacles. Here is how our team solves each one — with ASP.NET Core expertise, a fixed price, and a clear path from web platform to mobile app.

01
The Problem

Enterprise .NET Projects That Run Forever on Hourly Billing

Most .NET agencies quote a low estimate to win the project then bill hourly as scope expands. Enterprise web platforms and custom software projects are particularly vulnerable — complex integrations, changing business requirements, and open-ended development retainers mean the final invoice bears no resemblance to the original number.

01
Our Solution

Fixed-Price .NET Development — Scoped Before Code Starts

Every .NET project is scoped completely before development begins — web app, API, admin panel, integrations, and deployment configuration. One fixed price covering the complete deliverable. Our mobile app development clients who later extend their .NET backend to mobile get the same fixed-price model for both — one partner, one price discipline, across the full platform.

02
The Problem

.NET Platform Built — But No Path to Mobile Users

Businesses invest in a .NET web platform and admin system then realise their customers and field teams need a mobile app. Building mobile on top of an existing .NET backend should be straightforward — but most .NET agencies do not do mobile, forcing you to find a second vendor who does not understand your backend architecture.

02
Our Solution

One Team Builds Your .NET Backend and Your Mobile App

We build the .NET REST API and the mobile app that runs on top of it — same team, same architecture decisions, same codebase ownership. Your ASP.NET Core backend becomes the foundation for an iOS and Android mobile app development project. No second vendor. No API translation problems. No mobile team that does not understand your business logic.

03
The Problem

Legacy .NET Framework Systems Blocking Modern Development

Many businesses are running on .NET Framework 4.x — Windows-only, expensive to host, incompatible with modern cloud infrastructure, and locked out of the performance gains in ASP.NET Core. Every new feature takes longer to build, hosting costs remain high, and the gap between your platform and competitors widens each year.

03
Our Solution

ASP.NET Core Migration — Faster, Cheaper, Cloud-Ready

We migrate existing .NET Framework systems to ASP.NET Core incrementally — keeping your platform live throughout the migration, reducing cloud hosting costs, and unlocking Linux deployment on Azure or AWS. After migration, your modernised AI-powered .NET backend is ready to serve both web and mobile clients from a single codebase.

What Sets Our .NET Development Apart

Four non-negotiable commitments on every .NET project — and the reason clients across USA, UK and Canada choose our team for their web platform and then return to us for mobile app development on the same backend.

Fixed Price
No Hourly Billing

Fixed-Price .NET Development — Web Platform to Mobile App

Every .NET project is fully scoped and priced before development begins. The number in your proposal covers the complete web platform, API, and admin panel. When you are ready to extend to mobile, that project is fixed-price too. No hourly billing across the full digital platform lifecycle.

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.

01

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.

02

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.

03

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.

04

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.

05

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.

06

Deployment, Launch & Mobile Extension

We manage complete deployment to Azure, AWS, or your chosen infrastructure. Post-launch support is included for 90 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.

.NET Platforms Built for Every Stage of Growth

From a startup building their first .NET web platform to an enterprise modernising legacy software — we deliver every project at a fixed price. When your .NET platform is live and your users need a mobile app, our mobile app development team extends it to iOS and Android on the same backend. Clients across USA, UK, Canada and India.

ASP.NET Core Architecture That Scales From MVP to Enterprise

Every .NET platform we build uses clean architecture — separated into API, business logic, and data layers — hosted on Azure or AWS with auto-scaling. Your MVP launches fast and the same ASP.NET Core codebase scales to enterprise load without a rebuild. And when you need mobile, the same backend serves your iOS and Android app.

High-Performance REST APIs — Sub-100ms Response Times

ASP.NET Core is consistently the fastest mainstream web framework in TechEmpower benchmarks. We build REST APIs with sub-100ms response times using optimised Entity Framework queries, Redis caching, and async/await throughout. The same high-performance backend serves your web app and your mobile app clients simultaneously.

03

Clean Architecture — Testable, Maintainable, Handover-Ready

Every .NET codebase we deliver follows clean architecture with SOLID principles, dependency injection via Microsoft DI, and full test coverage using xUnit. When we hand over your platform, your internal team or any future developer can understand, extend, and maintain it without needing us to explain it.

Secure Architecture + DPDP Act Compliance in ASP.NET Core

Every .NET web application is built to industry-standard web application security best practices — SQL injection prevention, XSS protection, CSRF tokens, secure authentication with ASP.NET Core Identity, and encrypted data at rest. India DPDP Act compliance and secure data handling for international clients built into the data architecture from day one.

05

Fixed Price. Every Project. No Exceptions.

The price in your proposal is the price on your final invoice. No hourly billing, no scope-creep additions, no change request charges for agreed features. Fixed price is not a marketing claim at AZRIVA — it is a contractual commitment on every .NET engagement.

.NET Development — Frequently Asked Questions

Our team has answered the most common questions about our services.

Updated May 2026
Dot net development cost in India depends on project scope, complexity, and integration requirements. A simple ASP.NET Core web application or business portal starts from $8,000–$15,000. A mid-complexity platform with REST APIs, admin panel, and third-party integrations ranges from $15,000–$40,000. Enterprise .NET platforms with complex business logic and ERP integrations start from $40,000 upward. As a full-service mobile app development company in India, we also build the mobile app on top of your .NET backend at the same India pricing advantage. Contact us via our quote page for an estimate within 48 hours.
A simple ASP.NET Core web application takes 8–12 weeks from design sign-off to production deployment. A mid-complexity platform with APIs and integrations typically takes 14–20 weeks. Complex enterprise .NET systems take 24–40 weeks. We deliver a deployable build at the end of every two-week sprint throughout. After your .NET platform is live, extending to a mobile app on top of your existing backend typically adds 10–16 weeks for a cross-platform iOS and Android application.
We build with ASP.NET Core for web APIs and web applications, Entity Framework Core for database ORM, Blazor for server-rendered and WebAssembly UI, and SignalR for real-time functionality. Cloud hosting on Azure or AWS. SQL Server, PostgreSQL, and MySQL for databases. Every .NET codebase follows clean architecture with SOLID principles, dependency injection, and automated testing using xUnit. For AI-powered applications, we integrate Azure OpenAI Service and ML.NET directly into the ASP.NET Core backend.
Yes — this is one of the most common journeys our clients take. Your .NET REST API becomes the foundation for an iOS and Android mobile app development project. We audit your existing ASP.NET Core API for mobile readiness, add any mobile-specific endpoints needed, and build the cross-platform mobile app on top of your existing infrastructure. One backend. One team. Web and mobile from a single architecture — no duplication of business logic or database.
.NET Framework is the original Windows-only Microsoft runtime — mature and widely deployed in enterprise systems but no longer receiving major updates. ASP.NET Core is the modern cross-platform successor — runs on Windows, Linux, and macOS, significantly faster, cloud-native, and actively developed by Microsoft. For all new projects we build with ASP.NET Core. For existing .NET Framework systems, we offer migration to ASP.NET Core — reducing hosting costs and opening the path to Linux cloud deployment. A modernised ASP.NET Core backend also provides a better foundation for future mobile app development.
Yes. Every .NET project includes 90 days of post-launch support as standard — bug fixes, performance monitoring, security patches, dependency updates, and infrastructure scaling. After the initial period, we offer ongoing maintenance retainers. Microsoft releases .NET major versions annually, so having a maintenance arrangement keeps your platform on supported versions. Clients who extend their .NET platform to mobile app development benefit from unified maintenance across web and mobile from one India-based team.
Yes. We integrate Azure OpenAI Service, Microsoft Semantic Kernel, and ML.NET for on-premise machine learning into ASP.NET Core backends. Common implementations include AI-powered search, document processing, chatbots, predictive analytics, and automated data classification. Our AI app development team architects AI features as clean service layers within your .NET backend — not bolted-on external calls — so they scale with your platform and serve both your web app and your mobile app from a single AI layer.
.NET development costs in India are 60–70% lower than equivalent agencies in the USA, UK, or Australia. Our mobile app development company in India works IST with 4-hour daily overlap with UK and 10+ hours with USA. Fixed price means the saving is locked in from day one. Clients who start with a .NET web platform and later extend to mobile benefit from the same cost advantage across both engagements — one India-based partner for the full digital platform at consistent fixed pricing.
