When Companies Hire .NET Developers Through Coderio.
Building or Scaling Enterprise Backend Systems
.NET is one of the most capable platforms for enterprise backend development — performant, mature, and backed by Microsoft's long-term investment. When your product requires reliable, high-throughput APIs, complex business logic, or backend services that integrate deeply with Microsoft enterprise systems, our .NET developers build it with the architectural depth and engineering discipline the platform demands.
Modernizing a Legacy .NET Framework Application
Many organizations run critical business systems on .NET Framework 4.x — applications that are difficult to maintain, cannot run on modern infrastructure, and are increasingly expensive to extend. Our developers execute incremental modernization strategies — migrating to .NET 6/7/8, refactoring toward clean architecture, introducing proper testing, and containerizing workloads — without disrupting the business systems that depend on them.
Building Microservices Architecture in .NET
ASP.NET Core is one of the strongest platforms for microservices, and the .NET ecosystem has matured significantly around patterns like Clean Architecture, CQRS, and Domain-Driven Design. Our engineers design and implement .NET-based microservices that are independently deployable, well-tested, observable, and built for the operational realities of distributed systems at scale.
Building on Azure with .NET
.NET and Azure are Microsoft's deeply integrated stack, and building cloud-native applications that take full advantage of Azure's managed services — Service Bus, CosmosDB, Azure Functions, AKS, and Azure AD — requires engineers who understand both sides of the equation. Our developers design and implement Azure-native .NET architectures that are scalable, cost-efficient, and operationally sound.
Building Real-Time Applications with SignalR
SignalR is .NET's built-in solution for real-time, bidirectional communication — powering chat applications, live dashboards, collaborative tools, and notification systems. Our developers design and implement SignalR-based real-time features that are reliable, scalable with Azure SignalR Service, and properly integrated with your existing .NET backend.
Filling a Critical .NET Engineering Gap
A key .NET engineer is transitioning, on leave, or simply unavailable at a moment when your backend roadmap can't afford to slow down. We provide immediate, qualified coverage to keep your .NET services and delivery commitments on track.
Reinforcing for a High-Stakes Launch or Migration
Major backend releases, .NET Framework to .NET Core migrations, or enterprise system integrations often require temporary but elite reinforcement. We provide senior-level .NET talent for exactly these moments.
.NET FAQs.
- What is the difference between .NET Framework and .NET Core / .NET 6+?
.NET Framework is Microsoft’s original Windows-only runtime, first released in 2002, and remains in widespread use across enterprise systems. It is no longer receiving feature updates — only security patches. .NET Core was Microsoft’s cross-platform, open-source reimagining of .NET, which has since been unified into a single platform called simply .NET (version 5 and above). Modern .NET runs on Windows, Linux, and macOS, supports containerization, delivers significantly better performance than .NET Framework, and is the platform for all new Microsoft investment. If your systems are still on .NET Framework, migrating to modern .NET is a strategic priority our developers can help you execute. - What is the difference between ASP.NET Core MVC and Minimal APIs?
ASP.NET Core MVC is the traditional, convention-based approach to building web applications and APIs in .NET — with controllers, action methods, model binding, and view rendering for web UIs. Minimal APIs, introduced in .NET 6, provide a lightweight, function-based approach for building HTTP APIs with less ceremony and lower overhead, well-suited for microservices and simple API endpoints. Many .NET 8 applications use both patterns within the same project. Our developers are experienced in both and can advise on the right approach for your specific use case. - What is Clean Architecture and why do your .NET developers apply it?
Clean Architecture is an architectural pattern that separates application code into concentric layers — domain, application, infrastructure, and presentation — with dependencies pointing inward toward the core business logic. It ensures that business rules are independent of frameworks, databases, and external services, making applications significantly easier to test, maintain, and evolve over time. The .NET ecosystem has embraced Clean Architecture widely, and our developers apply it as a default for new projects and introduce it incrementally during legacy modernization engagements. - Can your .NET developers work with our existing SQL Server or Azure infrastructure?
Yes. Our engineers have extensive experience with SQL Server at all scales — query optimization, index tuning, stored procedures, replication, and migration strategies. For Azure infrastructure, we work with the full range of Azure managed services that .NET applications typically depend on, including Azure SQL, Azure Service Bus, CosmosDB, Azure AD, App Service, and AKS. We work within your current environment rather than requiring a rebuild from scratch. - How do your developers approach performance optimization in .NET?
Our engineers profile .NET applications using dotnet-trace, dotnet-counters, and BenchmarkDotNet to identify memory allocations, garbage collection pressure, thread contention, slow database queries, and inefficient async patterns. They apply techniques including Span<T> and memory pooling for allocation reduction, compiled queries in Entity Framework Core, response caching and output caching, async throughout the request pipeline, and connection pooling — addressing performance at the root rather than applying surface-level fixes. - Is .NET a good choice for new backend projects in 2025?
Yes. Modern .NET — particularly .NET 8 and the upcoming .NET 9 — is one of the highest-performing backend platforms available, consistently ranking at or near the top of the TechEmpower Framework Benchmarks. Microsoft’s continued investment in performance, cross-platform support, cloud-native capabilities, and AI integration via Semantic Kernel makes .NET a strong, future-proof choice for new enterprise backend projects. Combined with C#’s continued language evolution — records, pattern matching, nullable reference types, primary constructors — modern .NET is a significantly more productive and expressive platform than it was five years ago.

Only the Best .NET Developers.
Our rigorous vetting process does the hard work of finding the top developers.
Finding a .NET developer who can truly own an enterprise backend (not just implement controllers) requires evaluating depth that framework familiarity alone doesn’t guarantee. Our selection process combines technical screening, real code review, and deep technical interviews conducted by senior engineers, assessing .NET-specific expertise across C# language depth, ASP.NET Core architecture, data access patterns, distributed system design, performance optimization, and production operations. We don’t just verify that a developer knows Entity Framework or can scaffold an ASP.NET Core project; we verify that they understand the CLR, can design maintainable architectures at scale, reason through concurrency and performance challenges, and make sound technical decisions under real production constraints.
What sets our process apart is the bar we hold on the non-technical side. Working nearshore demands engineers who communicate proactively, adapt to your workflows, and operate as true team members rather than remote contractors. Every .NET developer we place has been evaluated for English fluency, responsiveness, and professional maturity. Because technical depth without collaboration is only half the equation.
