.NET Development Services
CrestCoder builds high-performance Node.js backends and APIs for businesses across India, Australia, South Africa, and the UK. .NET 10 LTS backends with ASP.NET Core, Entity Framework Core, and C# 14 — enterprise-grade architecture with the performance and tooling the modern .NET ecosystem provides.
.NET 10 (LTS, Nov 2025 to Nov 2028) brings C# 14, EF Core 10, and AI-ready features like vector search. Here is where .NET genuinely fits.
ASP.NET Core is a natural fit for enterprise backends — strong typing, dependency injection, and tooling that large teams and long-lived codebases need.
C# 14 brings field keyword, extension members, and improved pattern matching — less boilerplate, cleaner domain models.
EF Core 10 adds vector search, JSON data type support, and hybrid search — built-in support for AI workloads with SQL Server 2025 and Azure SQL.
.NET 10 runs on Linux, macOS, and Windows — deploy to containers, cloud, or on-prem without vendor lock-in.
REST and gRPC APIs on ASP.NET Core with built-in auth, model validation, and OpenAPI documentation.
Multi-tenant enterprise systems, admin portals, and internal tools with role-based access and audit logging.
.NET applications containerised with Docker and deployed to Azure, AWS, or on-prem Kubernetes when the project warrants it.
Blazor for .NET-native frontends, or ASP.NET Core APIs paired with React, Vue, or Angular when that is the better fit.
Entity Framework Core for SQL Server, PostgreSQL, or SQLite — migrations, queries, and data access done properly.
.NET version upgrades, security patches, and ongoing feature development under a monthly retainer.
Our catalog does not include a dedicated .NET case study — we are transparent about that. What we bring to .NET projects is the same enterprise-grade architecture discipline we apply across our backend work: clean layering, proper dependency injection, and codebases that new developers can onboard to without a month of archaeology.
We follow the patterns the .NET ecosystem itself recommends: repository pattern with EF Core, CQRS where complexity warrants it, proper use of middleware and DI, and API documentation via OpenAPI. The architecture is the same whether the codebase is greenfield or a migration from .NET Framework.
We build on .NET 10 LTS (supported to Nov 2028) and plan version upgrades as a scheduled engineering activity.
C#'s type system catches errors at compile time, not in production. Combined with nullable reference types and proper model validation.
Two-week sprints with a working demo at the end of each — you see real software, not slide decks.
Small enough that senior engineers stay hands-on, large enough to staff a dedicated team when you need one.
We map out API design, data model, and deployment strategy — cloud, containers, or on-prem — before writing code.
API contracts and EF Core data models defined early so your frontend team can build in parallel.
Two-week sprints with a working demo at the end of each, deployed to a staging environment you can access anytime.
Unit tests with xUnit, integration tests, and CI/CD pipeline setup before launch.
Production deployment, then an optional monthly retainer for .NET upgrades and continued feature work.
We reply within 24 hours with an honest architecture recommendation — no obligation.
