What is ASP.NET?

ASP.NET is Microsoft's high-performance framework for creating enterprise-grade web applications and backend APIs. It has evolved dramatically from its Windows-only origins into a modern, open-source platform that runs on any cloud environment or operating system, including Linux.

This transformation is why ASP.NET remains a top choice for engineering leaders. Its industry-leading performance, architectural flexibility, and enterprise-grade security provide a stable, low-risk foundation for applications that are designed for long-term growth and maintainability.

Why leading companies partner with BairesDev for ASP.NET development.

  • Top 1% ASP.NET talent

    We hire less than 1% of the engineers who apply to work with us. Each candidate goes through technical tests, architecture reviews, and scenario-based interviews. Only the very best make it through. This means your ASP.NET team is made up of senior engineers with 8-10+ years of experience building and running large systems in production. They know how to write clean code, solve tough problems, and improve project outcomes.

  • Flexible, Scalable Engagements

    We shape every engagement to fit your needs. Start with a few engineers for immediate impact, grow into a dedicated team as demand increases, or let us handle full delivery when scope requires it. Our model allows for quick adjustments as your priorities shift, often in a matter of weeks. So you can flex capacity without losing momentum.

  • Large Bench, Fast Onboarding

    We onboard senior ASP.NET engineers and assemble full teams in 2–4 weeks—far faster than internal hiring cycles. Because we maintain a 4000+ pre-vetted bench of top 1% talent, we can match the right engineers to your exact needs without delay. That speed and breadth allow you to respond to business demands without being slowed down by traditional hiring bottlenecks.

  • Proven Track Record

    We’ve delivered 1,400+ projects for companies ranging from high-growth startups to Fortune 500 enterprises like Google and eBay. Our engineers have built and modernized everything from large-scale customer portals to mission-critical internal platforms. That experience means we know the common pitfalls, scaling challenges, and best practices that keep delivery predictable and systems stable.

ASP.NET FAQ

Frequently Asked Questions

  • Why augment my team instead of hiring more full-time engineers?

    Hiring senior engineers can take 6+ months, and even then, finding the right fit is uncertain. Staff augmentation with BairesDev lets you bypass that cycle. We evaluate over 2.2M applicants per year and hire only the top 1%, so you get pre-vetted ASP.NET talent with 8–10+ years of proven experience.

    Not to mention, our 4000+ bench means we can assemble dev teams and onboard highly qualified engineers in 2-4 weeks. And thanks to our nearshore model, our engineers collaborate with your team just like in-house devs.

  • What's the realistic approach to modernizing a legacy .NET Framework monolith?

    The safest path isn’t a complete rewrite. It’s staged modernization. By peeling off pieces of functionality into new .NET Core services, you minimize risk and preserve business continuity.

    We’ve executed this kind of modernization for clients across industries. Our engineers work extensively in both legacy .NET Framework and modern .NET Core. We guide you through the transition step by step, protecting continuity while moving your architecture forward.

  • How does modern ASP.NET help manage cloud costs at scale?

    Its high performance is a direct cost lever. Handling more requests per node lets you run on smaller, cheaper servers. This efficiency reduces wasted CPU time and directly lowers your monthly cloud bill.

    We help clients capture those savings by architecting .NET solutions with cost optimization in mind. This includes containerization, observability, scaling policies, and resource governance across Azure, AWS, and GCP. Our work gives you predictable performance and a leaner cloud bill.

  • How viable is ASP.NET in a non-Azure (e.g., AWS or GCP) environment?

    Completely viable. Modern .NET is open-source and container-native, so it runs the same on AWS or GCP as it does on Azure without lock-in or performance tradeoffs.

    Where we help is guiding that choice. Our engineers have deep experience deploying .NET workloads across all major cloud platforms, from AWS ECS and Lambda to GCP’s GKE and Cloud Run. We can help you weigh costs, architecture fit, and long-term scalability to ensure your .NET apps perform at their best on whichever cloud you choose.

  • Is it still difficult to attract top engineering talent for the .NET ecosystem?

    Yes For many companies, attracting top .NET engineering talent is difficult, especially for senior roles, modern tech stacks, cloud/AI integration, etc. Competition is fierce, and roles often take months to fill.

    BairesDev removes that bottleneck. We provide top 1% .NET engineers with 8–10+ years of experience, fully vetted and ready to start in just 2–4 weeks.

  • When should we choose a microservices architecture over a monolith with ASP.NET?

    Microservices make sense when a business need—like independent scaling or faster team autonomy—outweighs their operational complexity. Often the smarter path is to begin with a modular monolith and carve out services as your system grows.

    That’s where we add value. Our engineers have modernized and scaled .NET applications for enterprises across industries, and we know when microservices unlock real value versus when they just add overhead. We’ll guide you to the right architecture for your stage and growth goals.

    Whether you’re modernizing a legacy platform or building something new, our solutions are designed to support heavy workloads and complex business logic while meeting strict standards for security and compliance

  • Headless CMS Development

    Modern content delivery requires the flexibility to serve content to multiple frontends, from websites to mobile apps. A traditional, monolithic CMS creates limitations by coupling your content tightly to a single presentation layer.

    We build powerful, API-first headless CMS platforms using ASP.NET. This approach decouples your content management backend from the frontend, allowing your development teams to use any modern technology like React or Vue to build fast, engaging user experiences.

  • ASP.NET E-commerce Development

    A successful e-commerce platform demands extreme scalability to handle traffic spikes, robust security for transactions, and the flexibility to integrate with various payment and shipping providers. Performance is directly tied to revenue.

    Our teams are experienced in building feature-rich online stores using proven .NET-based e-commerce platforms like nopCommerce and Virto Commerce, ensuring your solution is both powerful and highly customizable to fit your unique business model.

  • API Development & Systems Integration

    The value of modern applications is often determined by how well they connect to other business-critical systems. A poorly designed API or a brittle, insecure integration can create performance bottlenecks and expose your organization to unnecessary risk.

    Our teams design and build secure, scalable, and well-documented RESTful APIs that serve as a backbone for your ecosystem. We specialize in complex integrations, reliably connecting your new .NET applications to essential third-party platforms and legacy systems.

  • ASP.NET Legacy Modernization

    Legacy .NET applications often suffer from technical debt, slow deployment cycles, and limited compatibility with modern infrastructure. These issues create operational risk and hold back innovation.

    We provide expert teams to execute pragmatic modernization roadmaps. This typically involves a "strangler fig" approach, incrementally migrating business capabilities to modern, cloud-native .NET services. This method de-risks the process, shortens time to value, and avoids the disruption of a full rewrite.
