CSharp-Compile-Run-code

.NET is Microsoft’s free and open source framework for developing native software applications on Linux, macOS, and Windows. The power of cross-platform development allows developers to design, code, and run programs on a wide array of platforms.

This course is an introduction to developing .NET applications using C#. You’ll start start with a comprehensive review of C# and computer programming fundamentals: data types, conditionals, loops, methods, and more. You’ll then review the basics of object-oriented programming before diving into methods, exception handling, delegation, and events. With this foundation, you’ll continue building interfaces, collections, database operations, and multithreading. You’ll wrap up with process improvements using dynamic binding, garbage collection, and unmanaged resources.

By the end of this course, you’ll have hands-on experience with C# and .NET, and be ready to build applications using object-oriented programming principles on almost any platform.

Mastering C# and .NET

## Overview

The core of the TPL is the `Task` class, but developers interested in parallelizing some jobs in their apps must also consider the `Parallel` class (also part of the TPL).

The `Parallel` class is static and allows us to execute code in parallel. Similar to a method running as part of a `Task` instance, the `Parallel` class uses pool threads to achieve parallelism and asynchronous execution. The `Parallel` class gives us several options:

 - `Invoke()`: This method accepts an array of `Action` delegates, either in the form of an array or as separate parameters. Methods passed in execute in parallel.
 - `For()`: This method resembles the `for` loop but iterations execute in parallel.
 - `ForEach()`: This method is similar to a `foreach` loop but executes in parallel.

## Parallel invocation

The `Parallel.Invoke()` method accepts an array of `Action` delegates or an array of methods that conform to the `Action` delegate. The methods that are passed to `Invoke()`, by default, run in pool threads:
