ABOUT THIS COURSE
A deep understanding of design patterns and the ability to apply them to relevant design challenges is key to writing good code. They ensure the code is easy to understand and maintain, can be extended in the face of evolving requirements, and can be reused as needed.
This course will help you learn design patterns by providing context for using each design pattern and mapping it to common real-world problems that developers can relate to. It also provides hands-on code examples in C# to help apply the learned concepts. The course starts by explaining the SOLID design principles for writing good code followed by discussing the classical behavioral, creational, and structural design patterns in detail. The course also focuses on their strengths and weaknesses and the recurring challenges in software design that these patterns address.
After taking this course, you can use your knowledge of design patterns and best practices to create reliable, scalable, and maintainable software projects.
