Hire .NET developers who write enterprise-grade C# — not just code that compiles. Production .NET requires: dependency injection, async/await patterns, proper exception handling, Entity Framework query optimization (N+1 detection), and the architectural patterns (clean architecture, CQRS, mediator) that keep large codebases maintainable.
.NET production demands: ASP.NET Core for APIs with middleware, authentication (JWT, OpenID Connect), EF Core with migrations and performance tuning, unit testing (xUnit, Moq), Docker containerization, and Azure deployment (App Service, AKS, Functions).
