L stands for Liskov Substitution Principle in SOLID

• Liskov Substitution Principle states that objects of a superclass should be able to be replaced with objects of its subclass without affecting the correctness of the program

• This principle ensures that the behavior of the program remains consistent when new classes are added

• Violating this principle can lead to unexpected behavior and bugs in the program

Parallel programming in C# allows multiple tasks to be executed simultaneously for improved performance.

• Parallel programming can be achieved using the Task Parallel Library (TPL) in C#.

• TPL provides constructs like Parallel.For and Parallel.ForEach to execute loops in parallel.

• Parallel.Invoke can be used to execute multiple methods in parallel.

• Data parallelism can be achieved using PLINQ (Parallel LINQ) to execute LINQ ...read more
