What does it cost to hire senior .NET developers from Codieshub?

Senior .NET engineering at Codieshub is scoped to the engagement rather than quoted as a published hourly rate. A dedicated team typically pairs two senior .NET developers with a QA engineer. For defined-scope product builds, we price by milestone after a discovery sprint. For typical budgets and timelines, see our project cost estimator at codieshub.com/project-cost-estimation. All pricing is fully loaded, with no recruiter fees, benefits overhead, or equipment costs on your side.

Can Codieshub migrate our legacy .NET Framework application to modern .NET?

Yes, and we have a structured process for it. We begin with a dependency audit (NuGet packages, Windows-specific APIs, WCF services) and produce a migration risk map. For large codebases we use a strangler fig approach, routing traffic incrementally to the modernized service while the legacy system handles remaining workloads. Smaller codebases can often be lifted in a single focused sprint of 8–12 weeks. We've completed migrations for .NET Framework 3.5, 4.0, 4.5, and 4.8 applications.

How long does it take to build an ASP.NET Core API with EF Core from scratch?

A well-structured API covering authentication (JWT or Azure AD), CRUD operations over a normalized schema, and integration with one external service (payment gateway, CRM, etc.) typically takes 6–10 weeks for a two-engineer team. Adding real-time features (SignalR), background processing (Hangfire or Azure Functions), or a Blazor front-end adds 4–6 weeks per major component. We deliver a working, tested build at each two-week sprint boundary.

Do your .NET engineers have experience with domain-driven design and CQRS?

Yes. Our senior engineers have implemented DDD aggregate patterns, CQRS with MediatR, and event sourcing (EventStoreDB, Azure Event Hubs) on production systems. We're candid about when DDD is the right fit, complex domains with evolving business rules, versus when a simpler layered architecture delivers the same outcomes without the overhead. We discuss these trade-offs explicitly during technical discovery.

What testing practices do your .NET teams follow?

We write xUnit tests for domain logic and service-layer code, integration tests using WebApplicationFactory for API endpoints, and contract tests (Pact) for service-to-service interactions in microservices architectures. Code coverage is tracked via Coverlet and enforced as a CI gate. We use FluentAssertions for readable test output and Moq or NSubstitute for mock-based unit testing. Test files are co-located with the code they test, not buried in a separate project.

.NET Development Services

What does .NET development cover for enterprise teams?

.NET development for enterprise teams covers ASP.NET Core APIs and microservices, Blazor, SignalR real-time features, gRPC services, MAUI apps and Azure-native functions on one runtime, plus migrations from legacy .NET Framework. Codieshub begins with an architecture review of bounded contexts and data access, then applies DDD or CQRS only where the domain calls for it.

Last updated November 3, 2026

Stack: ASP.NET Core, EF Core, Blazor, SignalR, gRPC
Testing: xUnit, coverage gates, Roslyn analyzers

How we approach .NET Development

.NET is the platform enterprise teams reach for when correctness, performance, and long-term vendor support are non-negotiable. With .NET 8 now in LTS, the ecosystem spans everything from high-throughput ASP.NET Core APIs and microservices to desktop applications, MAUI mobile builds, and Azure-native serverless functions, all on a single runtime with first-class tooling support. Codieshub has delivered .NET solutions for insurance platforms, fintech back-office systems, and logistics SaaS products that process millions of records daily, giving our engineers hands-on experience with the enterprise integration patterns and performance characteristics that matter at scale.

C# and the .NET ecosystem reward discipline: strong typing catches whole categories of bugs before runtime, Entity Framework Core with properly tuned migrations keeps data access predictable, and ASP.NET Core's minimal API model makes building performant, versioned HTTP services simple. Our teams are fluent in the full .NET stack, from Blazor server-side rendering to SignalR real-time features to gRPC for internal service communication, and we select patterns based on your actual load profile, not framework fashion.

For companies already invested in Microsoft's ecosystem (Azure Active Directory, Azure Service Bus, SQL Server, or Power BI).NET is the natural backbone. Our architects understand how to build .NET services that integrate with these Azure-native services without creating hard lock-in, so you retain flexibility as your infrastructure needs evolve. We staff teams of senior engineers who have shipped to production, not recent bootcamp graduates still learning the framework.

The challenge

Enterprise .NET projects frequently stall when aging .NET Framework codebases resist modernization, when EF Core migrations are applied haphazardly and schema drift becomes a maintenance burden, or when teams mix architectural patterns (anemic models in one service, rich domain objects in another) until the codebase becomes inconsistent and hard to extend.

Our approach

Codieshub engineers start .NET engagements with an architecture review: we map bounded contexts, assess data access patterns, and identify where the existing codebase can be incrementally modernized versus where a targeted rewrite delivers better ROI. We apply Domain-Driven Design principles when the domain is complex and lean toward simpler CQRS with MediatR when it fits. We don't impose patterns for their own sake.

The outcome

Clients get a well-structured .NET codebase with explicit boundaries between layers, tested service logic, documented API contracts via OpenAPI/Swagger, and a CI/CD pipeline that runs xUnit tests, code coverage gates, and static analysis (Roslyn analyzers) on every pull request. Production deployments are containerized (Docker/Kubernetes or Azure App Service) with structured logging via Serilog/Application Insights.

Why Codieshub

Six reasons teams stay past the pilot.

The shortlist we get asked about on every call, what actually separates Codieshub from a dev shop.

Enterprise-Grade Reliability
.NET's strong typing, runtime performance, and Microsoft's long-term LTS commitment make it the default choice for financial, healthcare, and logistics systems where downtime and data integrity are business-critical.
High-Throughput API Performance
ASP.NET Core consistently ranks among the fastest web frameworks in TechEmpower benchmarks. Our teams tune middleware pipelines, connection pooling, and async I/O to deliver APIs that hold up under real production load.
Azure-Native Integration
From Azure AD B2C auth to Service Bus messaging to Cosmos DB and SQL Server, our .NET engineers build integrations that use Microsoft's managed services without creating brittle vendor coupling.
Microservices & gRPC
We architect .NET microservices with clearly defined service contracts, gRPC for internal communication, and distributed tracing (OpenTelemetry) so you can debug cross-service flows without log-diving.
Legacy Modernization
We migrate .NET Framework 4.x applications to modern .NET in staged phases, running both runtimes in parallel when needed, so you modernize without a big-bang rewrite that halts feature development.
Team Augmentation on Your Stack
Need two additional senior C# engineers for a 6-month sprint? We slot into your existing .NET team with your tooling (Azure DevOps, GitHub Actions, Jira) and coding standards, without imposing our own process.
