ASP.NET Development

ASP.NET Core Applications|Business Web Platforms|Secure HTTP Services

Sphere 10 builds ASP.NET Core systems for organisations that need dependable business software on the web. We deliver customer portals, administration systems and HTTP APIs with the application, data and hosting layers designed together. C# and .NET are central to our engineering, backed by the framework and products we maintain ourselves.

Choose the Right Web Application Structure

We select Razor, MVC, Minimal APIs or a component-based interface according to the actual user journey and integration requirements. A public content page, a data-entry workflow and an API consumed by other software have different needs. The design establishes authorization, validation, session ownership and the boundary between request handling and business rules before the screens multiply.

Our Sphere10 Framework contains separate ASP.NET Core hosting and MVC libraries. They supply lifecycle integration, logging adapters, request utilities and form helpers without forcing every application to load a desktop framework or a particular presentation layer. We build on that owned code where it fits the project.

Implement the Complete Transaction

A form submission must produce a correct business operation, not simply save whatever the browser sent. We implement server-side validation, record-level authorization and transaction boundaries with clear error results. Background work is separated from HTTP response lifetime, and external calls receive explicit timeout and retry policies.

Data access can use NHibernate, provider-specific SQL or another agreed approach. We review query plans and paging against representative data volumes. File uploads, exports and long-running reports are bounded so an ordinary user action cannot consume the application's available memory or block every other request.

Your Working Web Platform

Responsive pages or API endpoints covering the agreed workflows and permission roles.
A domain and persistence implementation with reviewed schema changes and migration instructions.
Integration contracts, representative fixtures and checks for validation, authorization and concurrent updates.
Deployment configuration, health checks and operational logging suited to the selected host.

Acceptance From Browser to Database

We demonstrate complete workflows with valid, invalid and unauthorized requests. Acceptance also covers direct navigation, session expiry, interrupted operations and the expected data volume. The delivery includes source code, build instructions, database setup and a reproducible deployment package. Your team receives a system that can be supported and extended through ordinary .NET tooling, with the agreed browser behaviour verified separately from backend unit tests.
