Our ASP.NET Development Services
Enterprise-grade web applications built on ASP.NET Core, designed to scale with your business.
ASP.NET Core Web App Development
Web apps built on ASP.NET Core (.NET 8+), C#, and Entity Framework Core. MVC, Razor Pages, and Blazor, all following Microsoft's recommended architecture patterns.
ASP.NET API Development
RESTful APIs using ASP.NET Core Web API. Versioning, rate limiting, JWT/OAuth 2.0 auth, response caching, and OpenAPI/Swagger documentation included.
ASP.NET MVC Development
Server-rendered web apps with the MVC pattern. Razor views, tag helpers, and clean separation of concerns. Ideal for content-heavy apps and admin panels.
.NET Microservices Development
Monolith-to-microservices migration. Docker, Kubernetes, gRPC, message queues (RabbitMQ, Azure Service Bus), and distributed tracing with Application Insights.
.NET Migration, Modernization & Support
Legacy .NET Framework to ASP.NET Core. On-premises to Azure or AWS. Database migrations, Entity Framework upgrades, version updates, and security patches.
ASP.NET Integration Services
Third-party integrations — CRMs (Salesforce, HubSpot), ERPs (SAP, Dynamics 365), payment gateways (Stripe, PayPal), and cloud services. Custom middleware and ETL pipelines.
.NET Tech Stack We Work With
Why Companies Choose Tech Exactly for .NET Development
Dedicated .NET engineers who plug into your workflow and ship production-ready code from week one.
Modern .NET Core Expertise
Our developers work with .NET 8+ and C# 12 — not legacy .NET Framework 4.x. We use ASP.NET Core's latest features: Minimal APIs, native AOT compilation, Blazor for interactive UIs, and built-in container support. If your project is on legacy .NET Framework, we modernize it.
Enterprise and Regulated Industry Experience
We build .NET applications for healthcare (HIPAA), fintech (PCI-DSS), and enterprise (SOC 2). ASP.NET's mature security model (Identity, Data Protection APIs, anti-forgery tokens) combined with our compliance experience means security is built into every layer.
Azure and Cloud-Native Development
.NET and Azure are a natural pair. We deploy to Azure App Service, Azure Functions (serverless), Azure SQL, and Azure Service Bus. For AWS shops, we deploy .NET Core to ECS, Lambda, and RDS. Containerized deployments with Docker/Kubernetes for teams that need platform-agnostic infrastructure.
Full Stack — Not Just Backend
ASP.NET is the backend, but we also build the frontend. Angular, React, or Blazor for web UIs. We handle the entire stack — database design, API development, frontend, DevOps, and cloud deployment. One team, one vendor, complete delivery.
48-Hour Onboarding
From approval to first standup in 48 hours. Your developer integrates into your existing workflow — Azure DevOps, GitHub, Slack, Jira. No multi-week procurement cycles.

We are proud of what we have built. Let us walk you through our projects.
Discover the Benefits of Our ASP.NET Development Company
Swift Execution
Our team of experts is well-versed in the intricacies of ASP.NET development. Their competence allows us to expedite the whole process keeping intact the performance and security of the app. In comparison to interpreted scripts, these are faster to execute.
Performance
Our priority is providing the customer with the optimal performance of the app. With attributes like JIT compilation, coaching services, and native optimization, we fine-tune the app with critical codes and ensure its operability in different environments.
Powerful Toolsets
At Tech Exactly, we equip our applications with a variety of powerful tools such as Team Explorer, Visual Studio, Debugging, Expression Blends, and Testing tools to enhance productivity and overall efficiency.
Built-in Support
With ASP.NET’s built-in support for APIs, we make an effortless integration of the client’s app with other web apps like HubSpot. We deliver the app specially built to your needs (whether it is synchronizing customer data or automating marketing campaigns or anything else).
Easy Maintenance
Owing to ASP.NET, the developers require less coding for the language. It eliminates unnecessary complexities and results in better readability and overall code quality.
Easy to Deploy
ASP.NET enables the developers with the in-built configuration data. This reduces the deployment time. Without the need for manual code, the developers arrange the system and parameters very smoothly.
Cross-Platform Support
Being an open-source framework, ASP.NET supports cross-platform support. This feature expands the overall reach of the applications.

This is why we do what we do
"I’m most impressed with Tech Exactly’s ability to understand our challenges and come up with options to resolve them."
With other vendors I’ve worked with, I have to spend a lot of time explaining the challenge to them, and sometimes, they still don’t understand it. Tech Exactly takes the time to listen to us and offers us 3 – 5 different options to achieve the expected results.

Frequently Asked Questions
A basic ASP.NET web application (admin portal, CRUD operations, user management) costs $20,000-$50,000. Mid-complexity apps with integrations, complex business logic, and role-based workflows range from $50,000-$100,000. Enterprise platforms with microservices, compliance requirements, and multi-tenant architecture can exceed $150,000. We provide detailed estimates after a discovery call.
ASP.NET Core (now just ".NET 8+") is the modern, cross-platform, actively developed version. ASP.NET Framework (4.x) is legacy and in maintenance mode; it only runs on Windows and won't receive new features. For all new projects, we use ASP.NET Core. For existing .NET Framework apps, we recommend a migration path to .NET Core for long-term maintainability, performance, and cross-platform deployment.
Yes. We handle .NET Framework to .NET Core migrations incrementally. We audit the existing codebase, identify breaking changes and deprecated APIs, and migrate module by module. Common migration work includes: upgrading Entity Framework to EF Core, replacing System.Web dependencies, updating authentication from OWIN to ASP.NET Core Identity, and moving from IIS-only hosting to cross-platform Kestrel.
Blazor is Microsoft's framework for building interactive web UIs using C# instead of JavaScript. Blazor Server runs C# on the server with SignalR for real-time updates. Blazor WebAssembly runs C# in the browser. Use Blazor if your team is C#-focused and you want to avoid maintaining a separate JavaScript/TypeScript frontend. Use Angular or React if your team prefers JavaScript or needs the broader ecosystem.
Yes. We build RESTful APIs using ASP.NET Core Web API (Controllers or Minimal APIs), with JWT/OAuth 2.0 authentication, versioning, rate limiting, response caching, and Swagger/OpenAPI documentation. For microservices, we use gRPC for inter-service communication and message queues (RabbitMQ, Azure Service Bus) for event-driven patterns.
Primarily Azure (App Service, Azure Functions, Azure SQL, Blob Storage, Service Bus) since .NET and Azure are tightly integrated. We also deploy to AWS (ECS, Lambda, RDS) and Google Cloud. For teams that need platform-agnostic deployment, we containerize with Docker and orchestrate with Kubernetes.
Yes. ASP.NET Core is one of the highest-performing web frameworks available — consistently ranking at the top of TechEmpower benchmarks. With proper architecture (caching, async/await patterns, connection pooling, horizontal scaling), ASP.NET Core handles thousands of concurrent requests. Our enterprise clients run .NET apps serving high-volume transactional workloads.
