.NET is the enterprise backend framework. Its performance characteristics — ASP.NET Core consistently ranks among the fastest web frameworks in independent benchmarks — combined with Microsoft's long-term support commitment, deep integration with Azure, and a mature ecosystem of libraries make it the choice for organizations building backend systems that need to perform reliably at scale for years. When you hire a .NET developer, you want someone writing modern C# with current framework patterns — not legacy Web Forms patterns that belong in a different decade.
C# is a language that has grown significantly more capable in recent versions — nullable reference types, records, pattern matching, LINQ, async/await with the Task parallel library, and source generators make modern C# genuinely pleasant to work in. When you hire .NET developers from Devvista, you get C# engineers who write modern, idiomatic .NET code — not legacy Web Forms developers who have not kept current with the ecosystem.

What Our .NET Developers Build
ASP.NET Core APIs
We build high-performance REST and gRPC APIs with ASP.NET Core — properly structured with the minimal API approach or MVC controllers depending on complexity, using middleware for authentication and authorization, FluentValidation for request validation, MediatR for CQRS patterns, and Serilog for structured logging. Our APIs are documented with Swagger/OpenAPI and tested with xUnit and integration tests against a real database.
Enterprise Application Development
Enterprise .NET applications often involve complex domain models, multiple bounded contexts, and integration with legacy systems. We apply Domain-Driven Design patterns where appropriate, build clean architecture with proper separation between domain, application, infrastructure, and presentation layers, and use Entity Framework Core with the patterns that keep database access performant and testable.
Microservices with .NET
We build .NET microservices using ASP.NET Core, communicating through message buses (MassTransit with RabbitMQ or Azure Service Bus) and HTTP. These services follow the patterns that make microservices manageable — proper service boundaries, circuit breakers with Polly, distributed tracing with OpenTelemetry, and health checks integrated with orchestration platforms.
Azure-Integrated Applications
Microsoft's ecosystem is a natural fit for .NET. We build applications that leverage Azure services — Azure Functions for serverless compute, Azure SQL for managed SQL Server, Azure Service Bus for messaging, Azure AD for identity, and Azure DevOps for CI/CD. Our developers are familiar with both the .NET SDK integrations and the managed identity patterns that make Azure security practical.
Legacy .NET Modernization
Organizations running .NET Framework 4.x applications on Windows Server need a migration path to .NET 8+ running on Linux containers. We manage these migrations — assessing compatibility, upgrading framework dependencies, refactoring Windows-specific code, and containerizing the application for deployment on modern infrastructure.
.NET Skills We Cover
Our .NET developers work with .NET 8 and ASP.NET Core, C# 12, Entity Framework Core 8, MediatR, AutoMapper, FluentValidation, Polly, Serilog, and xUnit. For messaging, they use MassTransit with RabbitMQ, Azure Service Bus, and AWS SQS. For containerization, they build Docker images for .NET and deploy to Azure AKS, AWS ECS, or bare Kubernetes. For databases, they work with SQL Server, PostgreSQL, and Cosmos DB.

Why Choose Devvista?
.NET developer quality varies significantly. Our assessment tests for clean architecture patterns, Entity Framework performance understanding, and async programming correctness — the things that separate experienced .NET engineers from those who know the syntax but not the platform.
Engagement Models
Full-time dedicated, part-time, or project-based. Enterprise projects typically benefit from a long-term dedicated relationship.
