HOW THIS IS DIFFERENT
Outsourced C# Development, Without the Usual Trade-Offs
Outsourcing .NET work usually means paying for hours and hoping for output. A BlastAsia team works inside your codebase and your sprint rhythm, and uses AI-assisted tooling so each engineer ships more.
âš TYPICAL .NET OUTSOURCING
X Months of ground-up development before a working release
X Requirements drift and rework as specs stay abstract
X Headcount is the only lever, so more output means more people
X Knowledge walks out the door when the contract ends
✦ A DEDICATED BLASTASIA .NET TEAM
✓ Developers, business analysts and QA assigned exclusively to your product
✓ Working software every 2-week sprint, in your repositories and your standards
✓ AI-assisted coding and automated testing raise each engineer's output
✓ Full source code ownership and documented handover
WHAT WE BUILD
C# and .NET Work We Take On
From new builds to long-running enterprise systems, the team covers the full Microsoft stack and the engineering around it.
Web Applications and APIs
ASP.NET Core applications, REST APIs and back-end services built for production scale. See our web development practice →
Legacy .NET Modernization
Move VB, classic ASP and older .NET Framework systems onto a current .NET stack, in place and without a multi-year rewrite. See App Modernization →
Azure Cloud Applications
Cloud-hosted .NET applications built on the Azure ecosystem, from new builds to lift-and-modernize moves. See Cloud App Development →
SQL Server and Data Layers
Database design, performance tuning and reporting for the SQL Server backends that .NET applications depend on.
Integrations
Connect your .NET systems to payment, ERP, identity and third-party services, with the integration kept maintainable.
Testing and DevOps
Automated testing and CI/CD built into the team, so releases are repeatable. See Software Quality Testing →

ENGAGEMENT OPTIONS
Choose How You Want to Work With Them
The same teams can join you in three ways. Pick the one that fits how well defined your scope is.
A .NET Team That Extends Yours
A dedicated, cross-functional team that works in your existing codebase or on a new build, as an extension of your in-house team, with BlastAsia handling the people side. Azure or the cloud provider of your choice.
Fixed-Scope or Continuous AI-Native Builds
For projects specified end to end, or ongoing AI-native delivery. These run on our standard development stack and deploy to the cloud and AI provider you prefer.

COMMON QUESTIONS
Outsourcing C# Development: FAQ
Why outsource C# development to the Philippines?
The Philippines has a deep pool of English-speaking engineers and a long track record in software outsourcing. BlastAsia has built software on the Microsoft stack from Pasig City since 2001, for clients in the US, Europe and Asia-Pacific, and time zones have never been a barrier.
Can you take over an existing .NET codebase?
Yes. A dedicated team can work inside your existing codebase, fix and enhance it, or modernize it step by step. We start with a review of the code and the spec.
Can you modernize a legacy .NET application?
Yes. We move older systems, such as VB, classic ASP and .NET Framework applications, onto a current .NET stack. See App Modernization for how that works.
Who owns the code?
You do. Every engagement includes full source code and IP ownership, and the work lives in your repositories.
Do you only do C#?
C# and .NET are our core specialization, but the team also works across the wider stack: Angular and modern JavaScript on the front end, SQL Server and Azure behind it. See our engineering expertise.
