Course Overview

The Microsoft course Dot NET with C# and ASP.NET API Development provides a comprehensive foundation in building modern, scalable web APIs using the .NET ecosystem. Designed for aspiring .NET developers, backend engineers, and full-stack developers, this course equips learners with the skills to design, develop, and deploy RESTful services using C# and ASP.NET Core. While there is no standalone certification exam exclusively for ASP.NET API development, the knowledge aligns closely with Microsoft’s Azure Developer Associate (AZ-204) certification, which emphasizes API development in cloud environments. With .NET remaining a cornerstone in enterprise application development, demand is strong—over 80% of .NET developer job postings require ASP.NET and C# skills, reflecting its widespread adoption across financial, healthcare, and SaaS industries.

Participants engage with core Microsoft technologies including .NET 8, ASP.NET Core Web API, Entity Framework Core, RESTful service design, and Azure integration. The course includes hands-on labs conducted in Visual Studio Code and the Azure Portal, where students build a fully functional CRUD-based API for managing product data using in-memory databases and dependency injection. A key project involves creating a controller-based web API that supports HTTP methods like GET, POST, PUT, and DELETE, while implementing model validation and API documentation via OpenAPI (Swagger). These labs simulate real-world development workflows, enabling students to test endpoints using REST Client extensions and command-line tools, ensuring practical readiness for production environments.

This training prepares candidates for roles requiring Microsoft Azure and .NET expertise, supporting career advancement toward certifications like the Microsoft Certified: Azure Developer Associate. Professionals with these skills command competitive salaries, with ASP.NET developers in the U.S. earning an average of $113,098 annually, and top earners surpassing $132,000. Koenig Solutions enhances this learning experience with Guaranteed-to-Run batches and 1-on-1 training options, ensuring personalized instruction using official Microsoft courseware. Graduates gain the expertise to contribute immediately to enterprise API development projects, positioning them for long-term success in cloud-native application development careers.
