.NET Development Services Built on ASP.NET Core and C#

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.

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.
