Next-Gen ASP.NET Application Development That Delivers
Looking for high-performance, scalable, and future-proof ASP.NET development? At TwinCore, we turn your product idea or legacy codebase into a modern digital platform using the full power of the ASP.NET ecosystem - from classic MVC to the latest .NET Core & Web API stacks.
With over 70 successful ASP.NET projects, Microsoft Certified developers, and 12+ years of expertise, we deliver custom enterprise-grade applications with bulletproof code, clear architecture, and reliable performance.
ASP.NET Development Services We Offer
At TwinCore, we provide a full spectrum of ASP.NET services tailored to your product stage and business needs:
Custom ASP.NET Development
We build ASP.NET applications from scratch — backend on C#, frontend with Razor or JS frameworks. You get clean code, easy maintenance, and fast delivery. Whether it’s an admin panel, internal tool, CRM, or full SaaS — we handle architecture, logic, integrations, and testing. The codebase works out of the box, with proper structure, database layer, and deployment to your hosting or cloud. We write it like for ourselves — no shortcuts, no fragile hacks, just clean ASP.NET that runs stable and can be supported without rewriting everything.
Performance Optimization
If your ASP.NET app loads slow, crashes under traffic, or eats memory — we’ll fix that. We use profiling tools to spot heavy code, long queries, and blocking threads. Then we refactor it: async calls, caching, background jobs, and clean DB access. You’ll see faster response times, smoother user experience, and less server load. Doesn’t matter if it's a legacy Web Forms site or modern .NET Core project — we make it move. No theory — we look at real logs, fix real bottlenecks, and prove it works better.
Migration to ASP.NET Core
Still on .NET Framework? We’ll move your app to ASP.NET Core. No data loss, no full rewrites. We take your codebase, clean up old parts, update packages, move to cross-platform. You get a faster app, less bugs, cheaper hosting, and support for new features. This isn’t just about “being modern” — old .NET holds back speed, scaling, and future work. We’ve done dozens of upgrades: monoliths, Web Forms, MVC 5 — we know where it breaks and how to avoid it. Your team keeps control — we do the heavy lifting.
ASP.NET Consulting
Got an ASP.NET app that’s slow, messy, or stuck? We review it and show what’s wrong: architecture, DB usage, async mistakes, dead code, or poor testing. We don’t sell buzzwords — just clean feedback and fixes. Want to split a monolith? Move to microservices? Push to cloud? We’ll show what to do — or do it for you. Need advice before you start building? We help plan that too. You talk to .NET engineers who’ve seen hundreds of apps and know what breaks, what scales, and what burns money.
Dedicated ASP.NET Developers
Need extra developers for your ASP.NET project? We provide engineers who’ve worked with C#, .NET Core, Blazor, EF, and frontend if needed. You set the tasks — we code. Daily updates, no babysitting. Full-time or part-time, remote and reliable. Ideal if you don’t want to hire in-house or need fast ramp-up. We match your stack, tools, and code style. You don’t get trainees — only engineers who know how real ASP.NET projects work. Interview them first — or we’ll replace free if not a fit.
Support & Maintenance
Your ASP.NET app needs updates, monitoring, and fixes. We handle that. No matter who built it — we’ll keep it alive, fix bugs, patch security issues, and monitor uptime. We handle hosting configs, database checks, memory leaks, and logs. You don’t have to explain everything — we get into code, figure it out, and fix what breaks. Ideal if you don’t have devs on staff, or your team is too busy. We keep your system fast, stable, and safe — with clear monthly reports and hands-on support.
ASP.NET Solutions We Create
We build ASP.NET-based platforms that power real-world businesses:
Enterprise Apps
We build custom ASP.NET apps for enterprise operations — not MVPs, but systems that run real business logic. From internal CRMs to dashboards and order tracking tools, we develop clean, maintainable .NET backends integrated with your ERP, identity providers, or legacy systems. Secure logins, RBAC, multi-language, reporting? All covered. Apps we build actually solve day-to-day problems — used by sales teams, admins, and managers, not just engineers. Hosted on AWS, Azure, or hybrid — we make sure your software runs stable and scales easily.
E-commerce platforms
We develop e-commerce platforms using ASP.NET Core and custom frontend stacks — perfect for B2B, wholesale, or businesses that outgrew Shopify and WooCommerce. You get custom checkout flows, vendor management, bulk pricing logic, and ERP integrations — not just a product page builder. We build admin panels, hook up APIs (shipping, payment, CRM), and handle database logic for inventory, orders, and delivery. Your store runs fast, handles high load, and works exactly how your team needs it — no themes, no plugins, just real software.
End-to-end Fleet Management systems
We develop fleet tracking and dispatch systems on ASP.NET — ideal for logistics, rentals, and delivery services. You can assign drivers, monitor vehicle status in real time, log fuel data, and sync with GPS hardware or carrier APIs. Our web apps include dispatch views, route history, alerts, and access control for roles like dispatcher, driver, or manager. Everything works in the browser, connects to databases and APIs, and gives you full control of vehicle and route operations — from one place. Works great on mobile too.
Cloud-based IoT
We build IoT dashboards using ASP.NET Core and SignalR for real-time control. Whether you need to monitor sensors, smart devices, or industrial machines — our web panels let users see current status, control outputs, and view trends. We connect via MQTT, REST APIs, or Modbus gateways. The UI is fast, works on tablets, and supports role-based access. Want to trigger actions when values spike? Done. Want a log of everything that changed in the last 24h? Already built in. Just say what needs tracking — we’ll wire it up.
Secure CRM, ERP & CMS platforms
We develop custom admin platforms for managing customer data, internal workflows, and dynamic content — built with ASP.NET and SQL Server (or PostgreSQL if needed). From simple CMS pages with WYSIWYG editors to full-blown CRMs with lead tracking, status flows, and team permissions — we build it under your logic, not someone else’s plugin mess. Need integrations with Salesforce, HubSpot, or 1C? We connect via API or webhook. The result: one system that stores, displays, and syncs your business-critical data — with a clean UI and stable backend.
Intelligent chatbots and microservices integrations
Our team builds ASP.NET-powered chatbot backends and microservice integrations that automate your workflow. You can process orders from Messenger, update CRM leads via chat, or trigger alerts from connected services. On the backend, we use APIs, message queues, and event-driven logic to sync systems and handle high load. Want chatbots in support or sales? We build with logic, not fluff. Want backend services to talk to each other without delays? We use queues and retries the right way. This is the .NET-level of automation — stable, trackable, and production-ready.

The Collaboration Models at TwinCore
We offer a few collaboration models as a .NET development company with custom solutions. Our partners and clients choose what model suits better for their projects.
Time & Material
You pay for a certain service or feature implemented in your business ecosystem. We decided who will work on this task, and you pay for our time and the result that satisfies your requirements specified during the initial consultation.
Dedicated Team
You hire a dedicated team of .NET developers that works only on your project under your supervision. They consult, develop, and deliver custom NET development services and features that you may change during the whole process. Regular updates and post-development maintenance are a great benefit of this collaboration model.
Hire .NET Talent
Hiring experienced developers for the outsource .NET development is what we can also offer. Choose the right talent needed to support your project – we can recommend hundreds of candidates with specific expertise and similar cases. This model is ideal if you prefer the contract-based outsourced models with hired talents who offer the right skills. It is the most flexible model where you can control all the aspects of .NET development. However, this model requires more engagement and control.
Why ASP.NET?
ASP.NET is the enterprise standard for a reason. It's fast, cross-platform, secure, and perfectly suited for modern cloud architectures. Combined with the power of .NET Core and the Microsoft ecosystem, it gives you a stable foundation to build software that lasts.
