Applied Domain-Driven Design in .NET
What is Domain Driven Design (DDD) really about? How might Command Query Responsibility Segregation (CQRS) help us to build better software? Far from being esoteric concepts, they can be harnessed by everyday developers to create long-lasting, flexible solutions.
DDD and CQRS are gaining in popularity because they attack genuine challenges in software development. This course balances explaining important underlying theory with both design- and code-focused exercises, giving participants both understanding and new practical development skills.
Rather than teaching a framework, the course teaches a factoring and some ways to implement it, highlighting the key pitfalls to avoid along the way. During the course, a small application will gradually be built up from scratch. The course also includes coverage of testing, how to apply the insights from the course to existing systems and how to scale out a system developed using CQRS.
In the course we use the latest .NET 5 and C# 9.
