.NET 7 minimal API from scratch | FULL COURSE | clean architecture, repository pattern, CQRS MediatR

In this course I want to provide you a project structure and code organization to get you started with real .NET 7 minimal API projects. It's a full course on this topic where I start from creating and explaining the project structure, setting up different layers using EF Core, repository pattern, CQRS and MediatR. The biggest part of the video is however around the .NET 7 minimal API, taking you from the initial setup, explaining route handlers, implementing all CRUD operations and so on. Last but not least, this course walks you through the process of refactoring the .NET 7 minimal API so that it becomes readable, maintainable and scalable. At the end, you'll have a full project structure organized according to modern architectural patterns that you can take as a template for your own projects.

WhatsApp for Windows Phone is one of the few apps on Windows 10 Mobile today that continues to receive frequent updates from its developer. Unfortunately, the app itself is one based on Silverlight, which is what apps built for Windows Phone 8.1 used back in 2014. This means the app isn't a Universal Windows Platform app (UWP,) and as such doesn't run across all the different Windows 10 platforms and devices available today.
