I am a software engineer with many years of experience in C# development, and I have a lot of experience in WPF project development. I use a three-tier architecture or domain-driven architecture to develop projects Objects, and use WPF features such as data binding, triggers, commands, value converters, and technologies such as multi-threading, Lambda, delegation, reflection, serialization, generics, MEF, etc. using design patterns such as factory mode and singleton mode to design code to ensure high-quality code design.
