.NET development company

10+ years building on the .NET platform · Rated 4.9/5 on Clutch by 35 clients

.NET 8+ is used by 20.7% of professional developers, according to the 2025 Stack Overflow Developer Survey, which places it among the most widely used platforms. Separately, Statista data puts overall .NET usage at 25.2% among developers worldwide, while the older .NET Framework (versions 1.0 to 4.8) still accounts for 16.4%. So a meaningful share of production systems have not yet moved to the newer platform.

Stack Overflow, GoDaddy, and UPS run their production infrastructure on .NET, and Microsoft’s customer directory lists dozens more. In a Microsoft case study, GoDaddy’s principal software architect credited the move to .NET Core with faster production performance and better scaling, even though the switch happened on a live system.

Bamboo Agile works in the same field. We are a software development company in Tallinn, Estonia, with over 20 years of experience in telecom, education, healthcare, finance, and other industries. Our clients include A1 Group, Orange, Mobile TeleSystems, and Sanofi. For .NET projects, the core of our stack is ASP.NET and Azure, a combination built for systems that must run for years without a rewrite.

.NET consultancy

Before development starts, a consultation answers two key questions: is .NET the right choice for your new project, and what slows down the system you already have.

Services in this area:

Technology stack assessment and framework selection
Architecture review of an existing .NET application
Migration plan for a move from .NET Framework to modern .NET
Code audit before an acquisition or before a new team or another .NET development company takes over
Performance and scalability assessment
Technical due diligence for investors

Custom .NET application development services

We build .NET applications in C# and ASP.NET Core for the web, desktop, or cloud, based on where the application needs to run. Many projects start when an off-the-shelf tool covers most needs but misses one key piece. Our job is to create that piece, and workarounds become unnecessary.

What this covers:

Web application development
Desktop software development for Windows
Cross-platform development for web, desktop, and mobile from a single codebase
Custom APIs and business logic
Database design and data management

Integration with Microsoft and third-party systems

.NET solutions connect well with other Microsoft technologies and third-party applications. With the right integration, your system gains new functionality and keeps its performance.

Common integration requests within our .NET development services:

Integration with Microsoft 365, Dynamics 365, and SharePoint
Payment and CRM system integration
Reporting and analytics integration
Connections between new and legacy systems that currently can’t exchange data
Single sign-on across your company’s tools

Legacy .NET framework modernization and monolithic refactoring

Many companies still run critical software on .NET Framework. Microsoft continues to support it, but new features, libraries, and cloud services target modern .NET, and fewer developers want to work with older code. We migrate these applications to modern .NET in stages, and the system stays in use throughout the process.

Moreover, AI tools help us map dependencies and spot refactoring opportunities before they become costly. As a result, stack upgrades and legacy migrations take 40–50% less time.

Typical .NET modernization services include:

Migration from .NET Framework to modern .NET
Replacement of outdated components such as Web Forms, WCF, and legacy desktop UI
Refactoring of hard-to-maintain code
Breakup of monoliths into modules or microservices
Transfer of on-premises applications to Azure or another cloud platform
Containerization and CI/CD setup for existing applications

Cloud migration

The target platform depends on where the rest of your infrastructure runs: Microsoft Azure, AWS, or a hybrid environment.

Main tasks:

Cloud migration and infrastructure setup
Modernization of legacy systems during the move
Scalable infrastructure
Deployment automation
Database migration and consolidation
Cloud cost and performance review

Maintenance and DevSecOps support

Maintenance is part of our .NET development services: for applications in production, we take care of performance optimization, dependency and security updates, and infrastructure monitoring.

Support covers:

Security patches and vulnerability fixes
Regular updates of the framework and dependencies
Performance analysis and optimization
Bug fixes and incident response
Infrastructure monitoring

Dedicated .NET developers

Our .NET engineers can join your team full-time or part-time. The format works well for projects that need specific expertise or last longer than one fixed-scope engagement with a .NET development company.

What you get:

Individual .NET engineers or full teams matched to your stack
Team size that adapts to each project phase
Direct integration into your workflow and tools
Senior engineers for architecture reviews and code audits
Expertise in web, desktop, cloud, and mobile .NET development

Signs it's time to modernize your .NET system

Problems in older .NET systems tend to build up gradually. These signals usually appear first.

Support for your version has already ended, or ends soon

.NET 6 and .NET 7 no longer receive security patches from Microsoft, and support for .NET 8 ends in November 2026. Any vulnerability discovered after the end of support stays open until the application is migrated.

Deploying a change takes longer than writing it did

If you still ship an application by copying files to a server, or if each release requires someone to watch logs for an afternoon, your infrastructure has fallen behind the application.

New features get bolted onto code that already does too much

When one new field requires changes in five unrelated files, the codebase has accumulated technical debt. This happens in any system that has changed over many years.

There's a part of the system nobody wants to touch

If your team avoids a module because no one knows what a change might break, the system needs structural work. Another patch will only make the problem worse.

Hosting costs keep climbing without more traffic to show for it

An application built for on-premises servers often runs inefficiently in the cloud if it was moved there without changes to its architecture.

Our .NET development process

Each project follows the same core stages, and you see progress at each of them.

Discovery

We study your business goals, current systems, and technical constraints. Then we work on a clear scope, a list of priorities, and an estimate of time and cost.

Architecture and planning

A senior .NET engineer designs the architecture, selects the stack, and plans integrations with your existing systems. For legacy projects, this stage includes a migration plan that keeps the system running throughout.

Development

The team works in short iterations and you can see the result at the end of each one. AI tools may handle routine code, while architecture decisions and production-related changes go through senior review.

Testing and quality assurance

Automated and manual tests run throughout development. This way, security checks and performance tests catch problems before they reach production.

Deployment

We set up CI/CD pipelines and release the application to Azure, AWS, or your own servers.

Support and evolution

After launch, we monitor the system, fix issues, and keep the framework and dependencies up to date. New features can be added as your business needs change.

Our .NET technology stack

Being an experienced custom application development company, Bamboo Agile monitors and adheres to the latest technological trends – we constantly enrich our well-established expertise with brand new tools, fresh methodologies, and skills.

AI can write .NET code. Here's what it can’t do

AI tools speed up many routine tasks in .NET development. Some decisions, however, still depend on the experience of a senior engineer. The table below shows how the work splits between the two.

.NET task	How AI helps	Role of an experienced .NET developer
ASP.NET Core controllers and Minimal APIs	Generates CRUD endpoints and boilerplate code quickly	Defines service boundaries and maps endpoints to your domain model
Migration from .NET Framework to .NET 8/9	Flags obsolete APIs and suggests replacements	Verifies that business logic survives breaking changes, especially in WCF and Web Forms
Entity Framework Core migrations	Drafts migration scripts from model changes	Reviews the generated SQL for performance on large tables and protects production data from loss
Blazor components	Produces working components from a description	Chooses between Server and WebAssembly hosting and designs state management, which affects the responsiveness of the whole app
Azure infrastructure costs	Suggests scaling rules and service tiers	Adapts the setup to real traffic patterns and failure modes based on production experience
Pull request reviews	Flags obvious bugs and style issues	Checks that the change solves the right problem and adds no security or scaling risks

Case studies

Here are the custom .NET software development projects our team has worked on and proud of.

Education

.NET school management platform built to digitize processes

Bamboo Agile built Znaj, a .NET (ASP.NET Core) platform that handles enrollment, grading, and school communication in one system. We designed and built the online payment flow for tuition, meals, and other fees, and built the platform from architecture through launch.

Energy

.NET desktop software for oil & gas exploration and production

Bamboo Agile added 2 .NET engineers to the client’s team. They have been working inside the client’s existing E&P desktop platform for 2 years. The team built a new feature that corrects the visualization of stratigraphic well layers, and maintained the live system throughout with no disruption to daily operations.

Why hire our .NET developers

Here is what you can expect from working with our .NET developers.

Flexible team size

You can hire dedicated .NET developers as a separate team or add individual engineers to your in-house team. Requests to scale up or down take one to two days.

AI-assisted development with senior review

AI tools take over scaffolding and boilerplate code, which speeds up routine work. Architecture decisions, database changes, and production-related code still go through a senior .NET engineer before they merge.

Full IP ownership

You own all code and architecture decisions once the project ships. Development can move in-house or to any custom .NET development company you choose at any time, and everything you’ve built stays with you.

Overlap with your working hours

Our developers are based in Europe, so their schedules match EU business hours and can shift to overlap with the US working day. Code reviews and quick questions get answers sooner instead of being postponed for the next day.

Enterprise and high-load experience

We have worked on enterprise systems for various industries. As a rule, these projects handle large user bases and heavy data loads, so architecture, performance, and stability get attention from the first sprint.

Secure development

ISO 27001 certification confirms the strength of our internal security processes. Every team member follows secure coding standards. Vulnerability checks take place at each stage of the development lifecycle, before issues turn into real threats.

Engagement models we offer

Projects differ in scope, timeline, and how closely your team wants to stay involved. Choose the model that fits your case, and we can adjust it later if the project changes.

Dedicated team

When you hire dedicated .NET developers, a full team of .NET developers works only on your project as part of your workflow. A good fit for long-term projects with a changing scope.

Staff augmentation

Individual .NET engineers join your existing in-house team to fill a skill gap or handle extra workload. You keep control of the project; we provide the people.

Time & material

You pay for the hours worked, and the scope can change as the project evolves. Choose it when you hire .NET developers before the requirements are fully defined.

Hire .NET developers in four steps

Four steps separate your request from the first day of development, and the process stays transparent at each of them.
