D/W array is a dynamic array in .Net that can grow or shrink in size. ArrayList is a collection class that can store objects of any type.

• D/W array is a resizable array that automatically adjusts its size as elements are added or removed.

• ArrayList is a collection class that can store objects of any type, allowing for flexibility in data storage.

• Example: D/W array - string[] myArray = new string[5]; ArrayList - ArrayList

Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.

• Dependency injection helps in achieving loose coupling between classes.

• It allows for easier testing and maintenance of code.

• There are three types of dependency injection - constructor injection, setter injection, and interface injection.

• Example: Instead of creating an instance of a class within an...read more

Injecting dependencies allows for better flexibility, testability, and maintainability in code.

• Injecting dependencies means passing objects that a class needs rather than creating them within the class.

• This allows for easier testing by mocking dependencies and swapping them out for different implementations.

• Dependency injection frameworks like Unity, Ninject, or Autofac can help manage dependencies.

• Example: Instead of ...read more

Garbage collection in .NET is an automatic memory management process that helps in reclaiming memory occupied by objects that are no longer in use.

• Garbage collection is a process where the runtime environment automatically deallocates memory that is no longer needed by the program.

• It helps in preventing memory leaks and improving the performance of the application.

• Garbage collection in .NET uses generations to categori...read more

Async is used to define a method that can be run asynchronously, while await is used to pause the execution of an async method until a task is complete.

• Async is used to define a method that can be run asynchronously.

• Await is used to pause the execution of an async method until a task is complete.

• Async methods can be called using the await keyword to run them asynchronously.

• Async and await are used in C# to simplify asy

async defines, await pauses execution in asynchronous programming in C#.

• async keyword is used to define a method as asynchronous in C#.

• await keyword is used to pause the execution of an asynchronous method until the awaited task completes.

• Asynchronous programming allows non-blocking execution of code, improving performance and responsiveness.

• Example: async Task<int> GetDataAsync() { await Task.Delay(1000); return
