ASP.NET Development Company in India
Build Fast, Secure Web Applications and APIs on ASP.NET Core
As a leading ASP.NET development company in India, Zenkins designs and ships production-grade web applications, RESTful and gRPC APIs, and enterprise portals on Microsoft’s ASP.NET Core framework. Our India-based engineering teams — operating from Ahmedabad — combine daily hands-on ASP.NET Core delivery with a global engagement model that gives international organisations access to senior framework specialists at competitive rates.
We build on ASP.NET Core MVC, Razor Pages, and Minimal APIs for web and API development, C# as the primary language, Blazor for interactive front-ends, and Azure for cloud deployment. Whether you need a greenfield ASP.NET Core application, a Web API backing a mobile app, or a migration off legacy ASP.NET MVC or Web Forms, Zenkins has the framework depth and track record to deliver it.
What Is ASP.NET Core and Why Do Enterprises Choose It?
ASP.NET Core is Microsoft’s open-source, cross-platform web framework for building web applications, HTTP APIs, and real-time services. It runs on Windows, Linux, and macOS, and replaced the older, Windows-only ASP.NET (Web Forms and MVC 5) as the framework Microsoft actively develops and recommends for new work.
ASP.NET Core’s enterprise adoption is driven by a request pipeline built around dependency injection and middleware from the ground up, which keeps cross-cutting concerns — logging, authentication, error handling — out of business logic. Independent TechEmpower benchmark rounds have repeatedly placed ASP.NET Core among the fastest general-purpose web frameworks tested, ahead of most Java, Node.js, and Python peers on comparable hardware. For organisations already running Microsoft infrastructure — Azure AD, SQL Server, Office 365 — ASP.NET Core integrates with far less custom glue code than competing frameworks require.
Zenkins is an ASP.NET development company in India with over a decade of experience across every generation of the framework. Our engineers work across ASP.NET Core MVC, Razor Pages, Minimal APIs, Blazor, and Entity Framework Core, and have delivered ASP.NET applications for clients in financial services, healthcare, retail, and professional services across the USA, UK, Australia, Canada, and India.
ASP.NET Core — Choosing the Right Model for Your Project
Not every ASP.NET Core project needs the same hosting model, and picking the wrong one early adds friction later. Here’s how Zenkins evaluates the decision:
| Use case | Recommended ASP.NET Core model | Why |
|---|---|---|
| Public marketing or content-driven site | Razor Pages or MVC (server-side rendering) | Fast first paint, strong SEO, simpler hosting |
| Internal business tool / admin portal | Blazor Server or MVC with Bootstrap | Rapid development, no separate JavaScript build pipeline required |
| Mobile app or SPA backend | ASP.NET Core Web API (Minimal API or controller-based) | Clean separation between frontend and backend teams |
| High-throughput internal microservice | Minimal API + gRPC for service-to-service calls | Lower per-request overhead, faster inter-service communication |
| Legacy ASP.NET Web Forms or MVC 5 app | Incremental migration to ASP.NET Core | Removes IIS/Windows lock-in, unlocks container and Linux deployment |
| Real-time dashboards or chat features | ASP.NET Core with SignalR | Persistent connections without a separate WebSocket stack |
Zenkins recommendation: All new ASP.NET projects should target ASP.NET Core on .NET 8 LTS. Applications still running classic ASP.NET Web Forms or MVC 5 should be assessed for migration, as they no longer receive framework-level investment from Microsoft.
Our ASP.NET Development Services
Zenkins delivers the full spectrum of ASP.NET work — from greenfield ASP.NET Core applications and API-first backends to migration off legacy ASP.NET codebases.
ASP.NET Core Web Application Development
Full web applications built with MVC and Razor Pages, choosing server-side rendering where SEO and initial load speed matter, or an API-first architecture where a React or Angular frontend is already in play. Every application starts with a layered structure that keeps domain logic independent of controllers and infrastructure code.
ASP.NET Core Web API & Microservice Development
RESTful and Minimal APIs designed contract-first using OpenAPI, with gRPC available for internal service-to-service calls where latency matters. Rate limiting, request validation, structured logging, and consistent error responses are built in from the first sprint, not retrofitted after launch.
ASP.NET MVC & Web Forms to ASP.NET Core Migration
For businesses still running ASP.NET MVC 5 or classic Web Forms, we plan and execute the move to ASP.NET Core — mapping incompatible APIs and session-state dependencies, sequencing the migration to avoid a disruptive big-bang cutover, and validating functional parity before go-live.
Enterprise Portals & Multi-Tenant Applications
Role-based access control, multi-tenancy, approval workflows, and reporting modules built for internal teams and customer-facing portals, with permission models designed to hold up as the organisation scales.
Authentication & Identity Integration
We implement ASP.NET Core Identity, IdentityServer/Duende, Azure AD (Entra ID), or third-party providers like Auth0 and Okta, using OAuth 2.0 and OpenID Connect so sessions and tokens follow the specification rather than a hand-rolled shortcut.
Blazor & Front-End Integration for ASP.NET
Our UI engineers pair ASP.NET Core backends with Bootstrap-based server-rendered views, Blazor components for teams that want to stay in C#, or a decoupled React/Angular frontend — whichever fits your team’s skillset and the product’s interactivity needs.
ASP.NET Application Maintenance & Upgrades
Ongoing support, .NET version upgrades, NuGet dependency updates, and performance tuning for ASP.NET applications — including ones Zenkins didn’t originally build.

Frequently Asked Questions
What is ASP.NET Core and how is it different from ASP.NET?
ASP.NET Core is Microsoft’s modern, open-source, cross-platform web framework for building web applications and APIs. Classic ASP.NET (Web Forms and MVC 5) is Windows-only and runs on the older .NET Framework, which is now in maintenance mode. ASP.NET Core runs on Windows, Linux, and macOS, and is the version Microsoft actively develops and recommends for all new projects.
Should I choose Razor Pages, MVC, or Minimal APIs for my project?
It depends on what you’re building. Razor Pages suit page-focused applications with simple flows, MVC suits applications with more complex controller logic and shared views, and Minimal APIs suit lightweight backend services where a full MVC pipeline is unnecessary overhead. We help clients choose based on the actual shape of the application rather than defaulting to one pattern.
Can you migrate our ASP.NET MVC or Web Forms application to ASP.NET Core?
Yes. This is one of our most common engagement types. We start with a compatibility assessment covering third-party dependencies, session-state usage, and any Windows-specific APIs, then propose a migration sequence — either incremental (strangler pattern) or a full rebuild, depending on codebase size and risk tolerance.
What databases work with ASP.NET Core applications?
ASP.NET Core applications we build typically use Entity Framework Core or Dapper against SQL Server, PostgreSQL, or MySQL, though we also work with MongoDB and other NoSQL stores when the data model calls for it.
How do you handle authentication in ASP.NET Core applications?
We implement ASP.NET Core Identity for applications that manage their own user store, or integrate with IdentityServer/Duende, Azure AD (Entra ID), Okta, or Auth0 when centralised identity is required. Token-based authentication uses OAuth 2.0 and JWT bearer tokens following the OpenID Connect specification.
Do you build APIs that other teams' frontends can consume?
Yes. Many of our ASP.NET Core engagements are pure backend API builds — REST or gRPC — consumed by mobile apps, React/Angular frontends, or third-party integrators. Every API is documented with OpenAPI/Swagger as part of delivery.
How long does an ASP.NET Core project typically take?
A focused API or internal tool can be delivered in 6–10 weeks. A full-featured customer-facing web application typically takes 3–5 months. Migration projects vary more widely depending on the size and age of the existing codebase — we provide a firm estimate after a technical review.
Do you support and maintain ASP.NET applications you didn't originally build?
Yes. We regularly take over ASP.NET and ASP.NET Core applications from other vendors or in-house teams that no longer have the capacity to maintain them, starting with a code and security audit before any new work begins.
Can ASP.NET Core applications be deployed outside of Windows servers?
Yes. ASP.NET Core is fully cross-platform. We deploy applications to Linux-based containers, Azure App Service, Azure Kubernetes Service, AWS, and on-premises Windows or Linux servers depending on what your infrastructure team already runs.
How much does ASP.NET Core application development cost?
A focused ASP.NET Core Web API with authentication and documentation typically ranges from USD 20,000 to USD 60,000. A full-stack ASP.NET Core web application with a Blazor or React frontend, database, and Azure deployment typically ranges from USD 50,000 to USD 180,000. Enterprise-scale portals with multi-tenancy and compliance requirements range higher. Zenkins provides a detailed proposal after an initial scoping session.
