In the context of Dynamics 365 development, SOLID principles refer to a set of design principles aimed at improving software maintainability and reducing complexity. The acronym SOLID stands for five core principles:

1. **Single Responsibility Principle**: A class should have only one reason to change, meaning it should have one job or responsibility. This leads to classes that are easier to understand, test, and maintain.

2. **Open/Closed Principle**: Software entities should be open for extension but closed for modification. This principle encourages developers to extend functionality without altering existing code, which helps in reducing the risk of introducing defects.

3. **Liskov Substitution Principle**: Objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program. This principle ensures that a subclass can stand in for its parent class, leading to more robust and reusable code.

4. **Interface Segregation Principle**: No client should be forced to depend on methods it does not use. This principle encourages creating smaller, more focused interfaces rather than a large, general-purpose interface, which leads to systems that are easier to understand and easier to implement.

5. **Dependency Inversion Principle**: High-level modules should not depend on
