Our .NET development services give B2B teams business applications, APIs and integrations that fit existing systems and that your own engineers can extend. One cross-functional team works under a named delivery lead and a technical architect, from written discovery scope to handover. Send a short brief to start scoping.
We build line-of-business software on .NET, such as workflow tools, internal systems and customer-facing portals. A technical architect is accountable for system design and code quality, so your team receives a codebase it can maintain and extend rather than a black box.
Your .NET services can connect to the databases, third-party platforms and Microsoft systems you already run. We agree the integration points in the written discovery scope, so dependencies are visible before development starts and surprises at release are less likely.
If your current .NET application is hard to change, we can extend it or rebuild parts of it in stages. We review what you have first. If another approach suits you better, we will say so after scoping.
| Consideration | .NET suits best | Netofficials may recommend another approach |
|---|---|---|
| Software type | Business and enterprise software such as internal tools, customer portals, APIs and integrations, where long-term maintainability and structured back-end logic matter. | After scoping, we will recommend a different stack if your product is mainly a content site or a short-lived prototype that .NET would over-engineer. |
| Existing systems | You already run Microsoft-oriented systems, SQL databases or internal services, and the new software has to connect to them cleanly. | If your estate is built around another platform and your team maintains it, we will say so after scoping and suggest the approach that fits it. |
| Team and ownership | Business applications, APIs and integrations that sit alongside existing Microsoft, SQL Server or Azure systems and need long-term maintainability | Your systems, hosting or team skills point to a different platform; if so, we will recommend that approach after scoping. |
We write down your requirements, users, existing Microsoft systems and databases, and the first-release scope for the .NET build.
You receiveYou sign off the written first-release scope
Our technical architect sets out the system design and technology choices for your .NET solution, alongside the user flows and interfaces, for your review.
You receiveYou approve the design and architecture before development starts
One cross-functional team builds your .NET APIs, integrations and application features in Agile sprints, with a named delivery lead running day-to-day progress.
You receiveYou attend a client-facing review at the end of every sprint
We test the .NET build, including integrations and critical workflows, against the acceptance criteria agreed with you before anything is released.
You receiveYou accept the release against the acceptance criteria agreed for your .NET build.
Netofficials deploys the .NET application to your environment, then hands over the documentation and deployment access your team needs to run it.
You receiveYou take over documentation and deployment access
| Layer | Example choices | Decision to review |
|---|---|---|
| Application & API | C#, ASP.NET Core, Web API | Business rules, hosting target and who consumes the API |
| Interface | Blazor, or React or Angular on ASP.NET Core APIs | Your team's frontend skills and how interactive the screens must be |
| Data & integrations | ASP.NET Core Web API, Entity Framework Core, SQL Server or PostgreSQL | Which existing services, integrations and databases must stay, and who owns each |
| Quality | xUnit or NUnit for unit and integration tests, Playwright for critical journeys | Critical workflows, integration risks and the acceptance criteria for release |
Send a short brief on your system, your users and the outcome you need, and we reply with questions, a proposed written scope and the cross-functional team we would put on it.
Netofficials builds a defined .NET application, API or integration to a fixed-price scope, which suits you if the requirements are clear enough to write down and you want a firm end point.
A dedicated India-based team of .NET and cross-functional engineers keeps extending your platform sprint after sprint, which suits you if the roadmap will keep growing beyond a first release.
Individual .NET engineers join your in-house team and work in your repositories and tickets, which suits you if you already have the architecture and management and need extra hands.
Cost and timeline on a .NET project depend on scope, the systems the software must connect to and the team you need. Integrations with existing databases, Microsoft systems or third-party APIs usually add the most uncertainty, followed by the number of user roles and workflows in the first release. We set these out in a written discovery scope with an estimate before any build starts. You can choose fixed-price project delivery, a dedicated India-based team or staff augmentation.
You own the code: IP assignment is confirmed in the contract before the build begins. For communication, we agree the communication window, meeting schedule and update cadence with you before work starts. A named delivery lead handles day-to-day progress, and you review the work at the end of every sprint. At release we hand over documentation and deployment access.
Yes, if your team already runs a .NET application, we can extend it, add integrations or take on defined modules. Discovery starts with the existing codebase, database and dependencies, so the first-release scope reflects what is already in place. A technical architect is accountable for system design, technology selection and code quality standards. If .NET is not the right fit for part of the work, we will say so after scoping and recommend another approach.
Tell us what you need to build, modernise or connect on .NET, and which systems it must work with. We reply with questions and a proposed scope. Your named delivery lead then walks you through a written discovery scope before any build starts, and the contract confirms IP assignment up front. If .NET is not the right fit, we will say so after scoping.
