/ Questions, answered

Choosing a .NET development company: questions we get asked.

What do your .NET development services include?

The full scope: custom development of web apps and mobile applications, API development, enterprise portals, desktop software, SaaS platforms, BI dashboards, and cloud work on Microsoft Azure. Engagements run from a single integration to end-to-end software development under one .NET services agreement.

How do I choose the right .NET development company?

Look for a .NET development company with a clear development process, deep technical expertise across the .NET ecosystem, and documented casework like the cases on this page. A reliable .NET development partner shows you real projects, puts senior technical skills on the discovery call, and agrees on scope and code ownership in writing.

What is .NET software development?

Software development on Microsoft technologies: C# code targeting the .NET platform and running on Windows, Linux, or in containers. Modern .NET is open source and cross-platform, so one codebase can serve web, desktop, and mobile platforms.

What can you build on the .NET platform?

.NET applications of every shape: enterprise web apps, line-of-business tools, multi-tenant SaaS, and .NET apps for the desktop. We also deliver .NET development solutions that pair a Microsoft backend with modern JavaScript frontends, software solutions sized to the problem rather than the framework.

Do you build cross-platform mobile applications with .NET?

Yes. Using .NET MAUI, our teams ship cross-platform mobile applications for iOS and Android from a shared C# codebase, alongside a mobile development practice that builds fully native apps. Cross-platform solutions cut duplicate work when web and mobile ship together.

How does a .NET development project start?

Every .NET development project starts with a software audit of the current estate, a definition of business objectives, and an architecture recommendation. You see the plan, the milestones, and the team before development begins.

Who manages the development process day to day?

A dedicated project manager runs project management for the engagement, and the .NET development team demos working software every sprint. You get direct communication with the engineers, not a filtered status report.

Can you optimize or extend existing solutions?

.NET software optimization is its own practice here: performance optimization, seamless integration with the systems you already run, and incremental modernization of existing solutions instead of risky rewrites, including older .NET MVC codebases.

Do you offer .NET software outsourcing?

Yes, in three shapes: team augmentation to fill skill gaps, a dedicated team that manages delivery end to end, and full .NET software outsourcing where Brainvire takes project responsibility. Outsourcing also removes the overhead of recruiting and onboarding .NET engineers in-house.

Which languages and tools does the team use?

C# first, with Visual Basic maintained where estates require it. Those programming languages sit on a comprehensive tech stack: Visual Studio, Entity Framework for data access, Blazor, and the extensive libraries of the .NET ecosystem, standardized on the .NET technologies your team can maintain.

How do you keep .NET applications secure?

.NET provides robust security features out of the box, and we add secure coding standards, vulnerability management, and quality assurance that covers functional, performance, and security testing before every release.

Can you automate business processes in .NET?

Business process automation is one of the most common asks: approval chains, document flows, and agentic background services that take repetitive business processes off your team's plate.

What Microsoft Azure services do you use?

App Service, Azure SQL, Functions, Service Bus, and AKS cover most builds. The cloud development practice designs around the Microsoft Azure services your workloads actually need, with scaling and cost tuning wired in from day one.

What makes Brainvire a strong .NET application development company?

The combination shown on this page: .NET application development backed by 2,500+ enterprise programs delivered, a 95% client retention rate, AI tooling in every build, and delivery from 10+ global offices.

When should a legacy .NET application be modernized?

When it struggles under increased load, blocks mobile access, or its framework version leaves security patches behind. Modernizing legacy systems is often more practical than rebuilding from scratch: the upgrade to .NET Core infrastructure keeps your business logic while improving performance, security, and the user interface.

Why choose .NET for enterprise software?

The .NET ecosystem supports cloud-native applications and integrates with the major cloud providers; its modular architecture lets .NET solutions scale alongside business demands; and a large developer community keeps best practices and reusable code libraries current, which shortens development timelines.

What does a .NET software development project cost?

It depends on scope, integrations, and compliance needs, so we publish no flat rates. Every .NET software development project here is estimated from an agreed-on backlog, with transparent budgeting in the contract and no surprise change orders.

Do development projects include support after launch?

Yes. Long-term support and maintenance are critical for stability after launch, so development projects here carry a software maintenance lane: monitoring, patching, and the ongoing performance of the .NET applications we ship.

How is quality assured on .NET projects?

Rigorous testing standards: automated unit tests, CI/CD pipelines, and a mix of manual and automated testing that keeps test coverage high on every .NET project, with agile sprints keeping progress iterative and requirements flexible.
