ASP.NET Core API
ASP.NET Core is Microsoft's modern web framework for building APIs. Performance is industry-leading (benchmarks: 2-3x faster than Node/Python). Learning takes 2-3 months for basics, another 2-3 for mastery (EF Core, dependency injection, middleware, async/await patterns). Enterprise demand is strong (Fortune 500 uses .NET). Mastery earns $120k-180k, with 15-20% premium in enterprise consulting.
