Dometrain is a UK-based online course platform focused entirely on .NET and the broader C# / .NET ecosystem, founded by Nick Chapsas — one of the most widely-followed independent .NET educators on YouTube. The platform launched as an instructor-curated alternative to Pluralsight's .NET track, with course material taught by working senior .NET engineers from Microsoft, JetBrains, and the broader C# community.
The roster includes some of the most authoritative voices on the platform: Stefan Pölz (.NET MVP), Steve Smith (Ardalis), Khalid Abuhakmeh (JetBrains), David Whitney, Filip Ekberg, Rocco Lupo, and many others. Course material covers the full modern .NET stack: ASP.NET Core, Entity Framework, MAUI for cross-platform mobile, the testing tracks (xUnit, integration testing), Azure deployment, and the deep CLR / performance material that separates Dometrain from generic .NET tutorial sites.
The CourseFlix listing under this source carries over 75 Dometrain courses spanning that range. Material is paid; Dometrain runs on per-course or membership pricing on the original platform. Courses are aimed at intermediate-and-up .NET developers building production applications.
