Netofficials designs, builds and modernises .NET applications for mid-market and enterprise teams, covering custom .NET application development, ASP.NET Core APIs, and migration from legacy .NET Framework systems.
.NET development services cover the design, build, integration and ongoing maintenance of software applications built on Microsoft's open-source, cross-platform developer platform, primarily using C#, Microsoft's statically typed object-oriented language, and ASP.NET Core, Microsoft's open-source web framework for APIs and server-side applications. Netofficials, an India-based software development company, delivers new builds, feature extensions, REST API layers and legacy modernisation for mid-market and enterprise clients in the US, UK and Australia.
.NET runs on Windows, Linux and macOS, giving organisations flexibility in hosting environment. ASP.NET Core handles high-throughput REST APIs and server-rendered web applications within the same ecosystem. Entity Framework Core, Microsoft's open-source object-relational mapper, manages relational data access against SQL Server, PostgreSQL and other databases. Netofficials applies SOLID principles, a set of five object-oriented design guidelines, and reviews security posture against the OWASP Top 10 list of critical web application security risks throughout each build.
.NET suits enterprise software where long Microsoft support cycles, strong typing, compliance audit trails and a mature tooling ecosystem are priorities. It fits teams already running Azure, Microsoft's cloud computing platform, since Azure App Service, Azure SQL and Azure Service Bus integrate directly with the runtime. It is not the right fit where the team's existing expertise is entirely in Node.js or Python and a rewrite is not justified. For organisations with ageing .NET Framework codebases, Netofficials provides legacy software modernisation where the existing logic has long-term value.
Engagements begin with a scoping call to map requirements, existing infrastructure and integration points. Netofficials then produces an architecture proposal, agrees a delivery model and assigns a team covering C# development, testing with xUnit, a free open-source unit testing framework for .NET, and deployment using Docker and Kubernetes. The client receives versioned source code, infrastructure-as-code scripts, API documentation and a handover session at each milestone.
What We Deliver
Netofficials builds multi-role portals, customer-facing platforms and internal tools using ASP.NET Core, Microsoft's open-source web framework. Data persistence uses Entity Framework Core, Microsoft's open-source object-relational mapper, targeting SQL Server or PostgreSQL. Suited to teams that need a long-term-support codebase with defined upgrade paths.
We design APIs consumed by web frontends, mobile clients and third-party platforms. REST APIs follow resource-based conventions with OpenAPI documentation and versioning. gRPC, a high-performance remote procedure call framework, suits low-latency internal service contracts. Both patterns support Azure API Management for access control and rate limiting.
Netofficials builds scheduled jobs, queue consumers and long-running background tasks using .NET's hosted service model. These run independently of the web layer, improving reliability under load. Typical uses include report generation, data ingestion pipelines and event-driven processing triggered by Azure Service Bus or similar message brokers.
For notifications, live dashboards and collaborative interfaces, Netofficials integrates SignalR, ASP.NET's library for real-time web functionality, into existing or new .NET applications. SignalR manages WebSocket connections with automatic fallback. This suits operations platforms, trading interfaces and any product where users need immediate data updates without manual refresh.
When a unified C# codebase across frontend and backend reduces context-switching for your team, Netofficials delivers Blazor, Microsoft's framework for building interactive web UIs in C#, in either WebAssembly or Server rendering modes. Component libraries, form validation and state management are scoped to your product's user roles and data model.
Netofficials packages .NET applications into Docker, an open-source containerisation platform, and orchestrates them on Kubernetes or Azure, Microsoft's cloud computing platform. CI/CD pipelines on GitHub Actions or Azure DevOps automate build, test and deployment. This delivery pattern suits teams requiring environment parity, horizontal scaling and repeatable release processes.
How We Work
Netofficials works with your CTO, product owner or engineering lead to capture functional requirements, integration points and non-functional constraints such as throughput, compliance and data residency. Architecture options are evaluated and documented in decision records. You receive a written scope, proposed stack and a module-level effort breakdown.
Architects define the Entity Framework Core data model, ASP.NET Core API contracts and, where applicable, Blazor UI wireframes before production code begins. Each artefact is reviewed and signed off by your team. You receive an architecture document, OpenAPI specification and a validated data model that governs all subsequent sprint work.
Development runs in two-week sprints in C# against the agreed .NET version. Each sprint closes with a working demo and a backlog review where your product owner can reprioritise. REST, gRPC or SignalR endpoints are built to the approved contracts. You receive version-controlled code increments and a sprint report after every cycle.
The team writes unit tests with xUnit, integration tests against staging data and runs performance profiling before each release candidate. Security is reviewed against the OWASP Top 10 list of critical web application risks. You receive test coverage reports, a security review summary and a signed-off build ready for deployment.
CI/CD pipelines on Azure DevOps or GitHub Actions push verified builds to Docker containers orchestrated by Kubernetes on your chosen cloud environment. At handover you receive full source code with IP assignment, deployment runbooks, API documentation and credentials. An optional support retainer covers post-launch maintenance and feature iterations.

Cost and Timeline Factors
Cost depends on the factors below, including scope complexity, integration surface, compliance requirements, infrastructure choices and engagement model. Netofficials provides a scoped estimate after a short brief, so buyers receive a grounded projection before committing to a project.
Get a scoped estimateMore user roles, modules and business rules increase design and development effort directly. Reducing scope to a defined MVP before build starts is the most effective way to control initial cost.
Each third-party system, legacy API or data migration adds discovery, mapping and testing work. Providing clean API documentation and data schemas for existing systems shortens this phase considerably.
GDPR, HIPAA or financial regulations require additional audit logging, encryption and access controls. Identifying applicable regulations before architecture begins avoids costly rework to the data and security layers.
Managed cloud services on Azure reduce operational DevOps work but add licensing cost. Self-hosted deployments lower licensing spend but require more infrastructure configuration and ongoing maintenance effort.
Fixed-scope contracts suit well-defined requirements; dedicated team or staff-augmentation models suit evolving roadmaps and add ongoing cost. Post-launch SLA commitments, monitoring and update cycles are a separate cost dimension from the initial build.
FAQ
Still deciding? Send a short brief and we reply with questions and a scope.
Ask us directly →Cost depends on the number of user roles, the complexity of business logic, third-party integrations such as payment gateways or ERP connectors, and compliance requirements like HIPAA or SOC 2. Infrastructure choices on Azure, the scope of automated testing with xUnit, and whether the application targets web, API or multiple surfaces each add to the total. Netofficials produces an itemised breakdown after a scoping call before any commitment is made.
New projects should use current .NET, Microsoft's open-source, cross-platform developer platform, which receives active feature development and long-term support releases. .NET Framework is the older Windows-only predecessor now in maintenance mode, receiving security fixes but no new features. The only reason to target .NET Framework is a hard dependency on a Windows-specific library or COM component that has no current .NET equivalent.
Netofficials, an India-based software development company, schedules a daily overlap window aligned to the client's morning hours for stand-ups and live reviews. Asynchronous communication covers the remaining hours through structured updates in tools such as Jira or Linear and documented decisions in Confluence or Notion. Sprint reviews and retrospectives are held at fixed cadences so clients in the US, UK or Australia maintain full visibility without requiring late-night availability.
The client owns all source code, database schemas, CI/CD pipeline configurations, and related intellectual property upon final payment. IP assignment terms are written into the contract before work begins. Netofficials transfers the full repository, including Docker and Kubernetes manifests and workflow files, at project close. Review the engagement models page for details on contract structure across fixed-scope and dedicated-team arrangements.
Yes. Netofficials begins with a codebase assessment to map dependencies, identify technical debt, and determine which modules can be migrated incrementally versus which require targeted rewrites. This assessment-first approach avoids unnecessary full rebuilds. Legacy software modernisation typically moves the application toward ASP.NET Core and current .NET, improving cross-platform portability and access to actively maintained libraries without disrupting live operations.
Netofficials writes unit tests using xUnit, a free open-source unit testing framework for .NET, alongside integration tests that verify behaviour across service boundaries. Security is reviewed against the OWASP Top 10, the Open Web Application Security Project's list of critical web application risks. Performance profiling runs before each release. Code is reviewed against SOLID principles, a set of five object-oriented design principles, to keep the codebase maintainable as it grows.
Security practices are applied at every layer. ASP.NET Core, Microsoft's open-source web framework, provides built-in middleware for authentication, authorisation, and HTTPS enforcement. Entity Framework Core, Microsoft's open-source object-relational mapper, uses parameterised queries by default to prevent SQL injection. Each release is reviewed against the OWASP Top 10. For regulated industries, Netofficials maps controls to the relevant compliance framework during the design phase rather than retrofitting them at the end.
Netofficials offers three models: fixed scope for projects with well-defined requirements and a set deliverable; dedicated team for ongoing product development where scope evolves sprint to sprint; and staff augmentation to place C# and ASP.NET Core engineers directly inside an existing team. The right model depends on how stable your requirements are, how much internal capacity you have, and whether you need a single accountable partner or individual contributors. See the engagement models page for a full comparison.
