Simple application that demonstrates how the task chaining works.
There are none methods from TPL library used. The app is based on asynchronous Tasks and async/await keywords approach.
App runs four consecutive tasks:
Task 1: Creates an array containing 10 integer elements.
Task 2: Returns previous array but its elements are multiplied by randomly generated number.
Task 3: Sorts the array in ascending order.
Task 4: Finds an average value of items of the array.
