Solid design principles are a set of guidelines for writing maintainable and scalable code.
Single Responsibility Principle (SRP) - each class should have only one responsibility
Open/Closed Principle (OCP) - classes should be open for extension but closed for modification
Liskov Substitution Principle (LSP) - subclasses should be able to replace their parent classes without affecting the program's correctness
Interface Se...

Ref and out are both used for passing arguments by reference in C#. Ref is bidirectional while out is unidirectional.
Ref and out are used to pass arguments by reference instead of by value
Ref is used for both input and output parameters while out is only used for output parameters

Developers can use pointers to directly manipulate memory, but this is not recommended.
C# also provides tools for managing memory usage, such as the IDisposable interface and the using statement.
Microservices, cloud-native, and serverless are the latest architectural trends in C#.
Microservices architecture is gaining popularity due to its scalability and flexibility.
Cloud-native architecture focuses on building applications that are optimized for cloud environments.
Serverless architecture allows developers to focus on writing code without worrying about infrastructure management.
Other trends include containeri...
