The Strategic Case for 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.

Senior ASP.NET talent

Our selection process is rigorous and we hire under 1% of applicants. Your team is staffed only with senior, full-time engineers who have 8+ years of experience working on complex ASP.NET systems in production. No juniors or freelancers. Just experienced engineers who ship.

Flexible engagement options without vendor lock-in

Start with a focused pod or embed a few seniors to stabilize a codebase. Scale to a dedicated team or ask us to run end-to-end delivery. We document everything, keep ownership clear, and make it easy for your internal team to assume control at any point.

Fast onboarding and workflow fit

We ramp in 2 to 4 weeks, often faster for staff augmentation. Our engineers immediately align with your tools and processes. Time zone overlap keeps feedback tight and decision cycles short.

Referenceable outcomes at scale

We have delivered complex solutions for more than 500 companies, including Rolls-Royce, Adobe, and Google. We have delivered hundreds of ASP.NET projects, from migrations to high-throughput APIs, partner portals, and data-heavy dashboards.

Cloud done right

We run ASP.NET on Azure or AWS using the simplest platform that meets your needs. That can mean App Service for speed, Kubernetes when you need control, or serverless for event-heavy workloads. Environments are defined as code, identity, and secrets are managed centrally, and scaling is tested before go-live.

Security and compliance you can verify

We follow OWASP guidance, enforce SSO and least-privilege access, and encrypt data in transit and at rest. Our work has cleared HIPAA, SOC 2, and ISO 27001 audits run by US clients, with audit trails preserved across environments.

ASP.NET FAQ

Frequently Asked Questions

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

Augmentation bypasses the 6+ month hiring cycle for senior architects. It’s a tactical move to embed elite, pre-vetted talent in weeks, ensuring you hit critical roadmap dates without the typical recruiting delays.

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

Avoid a high-risk ‘big bang’ rewrite. The proven approach is to incrementally carve off features into new microservices. This de-risks the process and requires a team experienced in both legacy and modern .NET.

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.

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

It's completely viable and a first-class citizen on any cloud. Modern .NET is open-source and container-native, running identically on AWS or GCP as it does on Azure, with no performance penalty or lock-in.

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

The .NET ecosystem attracts senior engineers focused on long-term, robust systems. Its top-tier performance and modern C# features make it highly appealing. Retention is about providing meaningful work, which team augmentation directly supports.

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

Use microservices only when a business need, like independent scaling, outweighs their operational complexity. We advise starting with a well-structured "modular monolith" and breaking out services pragmatically as your application evolves.

Engagement Models

How We Can Work With You.

Need a couple of extra software engineers on your team?

Get senior, production-ready developers who integrate directly into your internal team. They work your hours, join your standups, and follow your workflows—just like any full-time engineer.

Staff Augmentation

Need a few teams to deliver several projects in simultaneously?

Spin up focused, delivery-ready pods to handle full builds or workstreams. Together we align on priorities. Then our tech PMs lead the team and drive delivery to maintain velocity and consistency.

Software Development Teams

Want to offload everything to us, from start to finish?

Hand off the full project lifecycle, from planning to deployment. You define the outcomes. We take full ownership of the execution and keep you looped in every step of the way.

ASP.NET Development Services Provided

Custom Application Development

If your business runs on custom software, these applications must be fast, reliable, and built on a technology stack that supports long-term growth and simplifies maintenance.

We specialize in building high-performance web applications using modern ASP.NET Core and C#. Our teams deliver secure, data-driven platforms with clean architecture, ensuring they are scalable and easy to evolve as your business needs change.

ASP.NET Enterprise App Development

Large organizations require applications that securely integrate with a complex ecosystem of existing solutions. Adherence to strict security protocols and corporate governance is critical.

We build robust enterprise solutions designed to handle high-traffic workloads and complex business logic. Our expertise extends to integrating with legacy data sources, CRMs, and ERP systems, ensuring your new application integrates cohesively with your existing systems.

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 an inability to leverage modern infrastructure. This presents a significant operational risk and makes attracting new engineering talent difficult.

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 and delivers value faster than a full rewrite.
