Unlocking the Power of Concurrency and Parallelism in Modern .NET Applications What is Concurrency? Concurrency, a vital concept in modern programming, refers to a program's ability to execute multiple independent operations simultaneously, with these concurrent tasks often occurring in an overlapping fashion. Importantly, the order in which these tasks are executed doesn't affect the final result, as long as they remain independent. They can start, run, and complete in an interleaved manner without the need to run at the exact same moment. It's crucial to note that concurrency and parallelism aren't synonymous, though concurrency serves as a means to achieve parallelism. Parallelism entails the execution of two or more tasks at the same instant, or in other words, simultaneously. Even in the case of a single-core CPU, which can't run multiple tasks simultaneously, it can offer a form of virtual parallelism by rapidly and seamlessly switching between differe...
