.NET in 2026

.NET 10 LTS is
the enterprise standard

.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.

Enterprise backends

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 productivity

C# 14 brings field keyword, extension members, and improved pattern matching — less boilerplate, cleaner domain models.

AI-ready with EF Core 10

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.

Cross-platform

.NET 10 runs on Linux, macOS, and Windows — deploy to containers, cloud, or on-prem without vendor lock-in.

What We Build

.NET development
services we deliver

01

ASP.NET Core APIs

REST and gRPC APIs on ASP.NET Core with built-in auth, model validation, and OpenAPI documentation.

02

Enterprise Applications

Multi-tenant enterprise systems, admin portals, and internal tools with role-based access and audit logging.

03

Cloud-Native & Containers

.NET applications containerised with Docker and deployed to Azure, AWS, or on-prem Kubernetes when the project warrants it.

04

Blazor & Frontend

Blazor for .NET-native frontends, or ASP.NET Core APIs paired with React, Vue, or Angular when that is the better fit.

05

Database & EF Core

Entity Framework Core for SQL Server, PostgreSQL, or SQLite — migrations, queries, and data access done properly.

06

Maintenance & .NET Upgrades

.NET version upgrades, security patches, and ongoing feature development under a monthly retainer.

Enterprise Backend Architecture

Challenge

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.

Solution

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.

Why CrestCoder

.NET backends
built to last

.NET 10 LTS, production-ready

We build on .NET 10 LTS (supported to Nov 2028) and plan version upgrades as a scheduled engineering activity.

Strong typing from day one

C#'s type system catches errors at compile time, not in production. Combined with nullable reference types and proper model validation.

Full project visibility

Two-week sprints with a working demo at the end of each — you see real software, not slide decks.

25-30 person team, senior-led

Small enough that senior engineers stay hands-on, large enough to staff a dedicated team when you need one.

How We Work

Our .NET
development process

01

Discovery & architecture

We map out API design, data model, and deployment strategy — cloud, containers, or on-prem — before writing code.

02

API & data design

API contracts and EF Core data models defined early so your frontend team can build in parallel.

03

Agile development

Two-week sprints with a working demo at the end of each, deployed to a staging environment you can access anytime.

04

Testing & CI/CD

Unit tests with xUnit, integration tests, and CI/CD pipeline setup before launch.

05

Launch & support

Production deployment, then an optional monthly retainer for .NET upgrades and continued feature work.

Common Questions

Frequently
asked questions

Still have questions? Contact us directly.

Which version of .NET do you use?+
.NET 10 for all new projects — the current LTS release (supported until November 2028) with C# 14, ASP.NET Core 10, and EF Core 10. For existing applications, we handle migrations from .NET 6, 8, or 9 with a clear upgrade plan.
ASP.NET Core or Blazor?+
ASP.NET Core for API backends serving separate frontends (React, Vue, mobile). Blazor when the team wants to stay fully in C# for both backend and frontend. We recommend based on your team and project.
Can .NET run on Linux and containers?+
Yes — .NET has been fully cross-platform since .NET Core. We deploy to Linux containers, Azure App Service, AWS, or on-prem Windows servers depending on your infrastructure. There is no Windows lock-in.
Can you migrate from .NET Framework?+
Yes. We handle migrations from legacy .NET Framework to modern .NET 10, including breaking changes between major versions, package replacements, and EF Core migration from EF6.
Do you work with Azure and SQL Server?+
Yes — Azure is a natural deployment target for .NET applications, and SQL Server is the most common database pairing. We also work with PostgreSQL and other databases when that is a better fit for the project.
How do you price a .NET project?+
Most projects are quoted as a fixed price after a discovery call. A standard Node.js API typically starts around $5,000-$12,000. Enterprise backends or backends with complex business logic and integrations usually run $15,000-$45,000, depending on scope.
