Code Maze (code-maze.com) is a Croatian-based .NET / C# tutorial publisher run by Marinko Spasojević. The platform has built one of the larger English-language reference catalogs for ASP.NET Core, Blazor, and the modern .NET ecosystem — with both free written tutorials and a paid course catalog that goes deeper.
The CourseFlix listing carries three Code Maze courses: Microservices in .NET (covering the modern .NET microservices stack with Docker and Kubernetes), Blazor WebAssembly (full-stack C# in the browser), and C#/.NET Interview Mastery — Hands-On Edition (2026) (the technical-interview prep aimed at .NET-focused roles).
Material is paid and aimed at .NET developers building production applications or preparing for .NET-focused engineering interviews. For broader content, see CourseFlix's C# category page.
