ASP.NET Core and React Development Services

Facile Technolab builds full-stack web applications with an ASP.NET Core backend and a React frontend — a pairing we use often because it gives clients a secure, high-performance API layer combined with a frontend ecosystem that's fast to develop in and easy to hire for. We work with clients across the US, Europe, and Australia, building new applications and adding React frontends to existing ASP.NET Core APIs.

Our Capabilities in ASP.NET Core

On the backend, our ASP.NET Core work draws on the same toolset across projects not reinvented each time, but applied based on what each project actually needs.

  • Experience configuring Serilog, Sentry, and Datadog for application logging and monitoring
  • Experience integrating AWS S3, AWS Systems Manager, AWS ElastiCache, and AWS ECS where projects run on AWS
  • Experience using Redis for distributed caching and application performance
  • Experience using SignalR for real-time features — live updates, notifications, chat
  • Experience with Azure Blob Storage, Azure App Service, Azure SQL, and other Azure services
  • Integrations with Google Maps, Google Analytics, Google Tag Manager,and other Google APIs and SDKs for .NET
  • Payment gateway integrations including Stripe, PayPal, and region-specific processors
  • Integrations with SyncFusion, DevExpress, Telerik Kendo UI, Power BI, and Grafana for dashboards and reporting
  • API integrations with Twilio, SendGrid, Xero, HubSpot, and similar third-party tools

Our Capabilities in React

On the frontend, our React work follows current React patterns and tooling not the React of several years ago.

  • Convert Figma designs into pixel-accurate React components
  • Component-based development built for re-use across the application
  • State management with Redux Toolkit or Zustand, depending on project complexity
  • Data fetching and caching with React Query (TanStack Query) for applications that talk to ASP.NET Core APIs heavily
  • UI built with Tailwind CSS, Material UI, or component libraries matched to the project's design system
  • Testing with Jest and React Testing Library
  • Component documentation with Storybook on larger projects where multiple developers work on shared UI

How We Work

  • Agile development with two-week sprints
  • Developers participate directly in backlog grooming, estimation, and sprint planning not just execution
  • Daily time tracking, ticket updates, and regular commits so progress is visible throughout, not just at milestones
  • Timezone overlap arranged to suit US, European, and Australian working hours
  • Senior and mid-level full-stack developers available for fast-paced hiring needs

What We Build

A full-stack ASP.NET Core and React project can mean different things depending on where you're starting from. Here's how we typically approach it.

New Full-Stack Applications

We design and build the application from scratch — ASP.NET Core API on the backend, React frontend, with the architecture planned around your specific requirements rather than a generic template. This includes authentication, data models, API design, and the React component structure, all planned together so the two layers fit cleanly.

Adding a React Frontend to an Existing ASP.NET Core API

If you already have an ASP.NET Core backend — possibly built by another team — and need a new frontend, or need to replace an existing one (often an older Angular, jQuery, or Razor-based frontend), we build the React application against your existing API. This is a common project type for us, and it typically starts with reviewing your existing API to understand what's available before any frontend work begins.

Modernizing Older .NET Applications with a React Frontend

For applications running on older ASP.NET MVC or Web Forms with outdated frontends, one modernization path is building a new React frontend that talks to a modernized (or modernizing) ASP.NET Core API — allowing the frontend to be replaced first while backend modernization continues in parallel, or vice versa.

Ongoing Development and Support

For applications already in production, we provide ongoing feature development, bug fixes, and performance work across both the React frontend and ASP.NET Core backend — as a dedicated team or as an extension of your existing one.

Why ASP.NET Core and React Together?

ASP.NET Core and React is one of the most common full-stack combinations we work with, for a few practical reasons. ASP.NET Core gives you a fast, secure, well-typed backend with strong tooling and — if your organization uses it direct integration with Azure and other Microsoft infrastructure. React gives you one of the largest frontend developer communities in the world, a mature component ecosystem, and a clear separation between frontend and backend that lets two teams (or one full-stack team) work without blocking each other.

Using full-stack developers who can move between both layers, rather than maintaining entirely separate frontend and backend teams, is something we recommend where it fits in our experience it can reduce overall project costs by around 20%, largely by cutting down on coordination overhead between teams.

Pairing ASP.NET Core with React vs. Other Frontends

React isn't the only frontend we pair with ASP.NET Core — we also build full-stack applications with Angular and Vue. The right choice depends mostly on your team and what you're trying to achieve:

  • React tends to fit well when you want the largest possible hiring pool, a flexible component-based architecture, and don't need Angular's more opinionated structure
  • Angular tends to fit well for larger enterprise teams that benefit from a more structured, TypeScript-first framework
  • Vue tends to fit well for teams wanting a lighter-weight framework with a gentler learning curve

Frequently Asked Questions about .NET Core and React.JS Development

Find answers to common queries about our .NET Core and React.JS development services.

Why pair React with ASP.NET Core instead of React with Node.js?

Both are common pairings, and React works equally well with either backend. ASP.NET Core tends to be the better fit when the backend needs to handle significant business logic, integrate with Microsoft infrastructure (Azure, SQL Server, Active Directory), or when performance on compute-heavy operations matters. If you're choosing between the two, our guide on ASP.NET Core vs Node.js covers this in more depth — the short version is that the choice usually comes down to your existing infrastructure and team, not React itself, since React doesn't change based on what backend it talks to.

Do we need separate frontend and backend developers, or can one team handle both?

One team can handle both, and for many projects this is more efficient. Full-stack developers who work across ASP.NET Core and React can move between the API and the frontend as needed, without the coordination overhead of two separate teams handing work back and forth. For larger projects with more specialized needs on either side, splitting the team can still make sense — it depends on project size and complexity more than on the technologies themselves.

Can you take over an existing React and ASP.NET Core application built by another team?

Yes. This is a common starting point for new engagements. We begin with a review of both the API and the frontend codebase to understand the current architecture, identify any immediate issues, and establish a baseline before making changes. This applies whether you need ongoing maintenance, new features, or a significant rework of either layer.

How do the React frontend and ASP.NET Core backend communicate?

Most commonly through REST APIs, which is the standard pattern for ASP.NET Core and React applications. For features that need real-time updates live notifications, chat, dashboards that update without a page refresh we use SignalR alongside the REST API to push updates from the backend to the React frontend directly.

Can you migrate an existing Angular or Vue frontend to React while keeping our ASP.NET Core backend?

Yes. Since the frontend and backend communicate through APIs, the backend doesn't need to change for a frontend framework migration. We'd typically start by reviewing the existing API to confirm it supports what the new React frontend needs, then build the React application against that API — migrating page by page or section by section rather than requiring a full cutover on day one.

How do you handle security in .NET Core and React.JS applications?

We implement industry-standard security practices to protect your application and user data.

Can you integrate third-party APIs and services in .NET Core and React.JS projects?

Yes, we can seamlessly integrate third-party APIs and services to enhance your application's functionality.

What industries have you served with .NET Core and React.JS development?

We have served clients from various industries, including healthcare, e-commerce, finance, and more.
