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

**(True or False)** A `string` object is mutable. We can perform operations on it without creating a new object.

(True or False) A <code>string</code> object is mutable. We can perform operations on it without creating a new object.

Consider the following code:

```C#
string message = "Hello World!";

foreach (var item in message)
{
    Console.WriteLine(item);
}
```

What is the type of `item`?

Consider the following code:
<pre><code class="language-C#">string message = &quot;Hello World!&quot;;

foreach (var item in message)
{
 Console.WriteLine(item);
}
</code></pre>
What is the type of <code>item</code>?

How is the following operation called?

```C#
var message = "Hello" + ", Mark!";
```

How is the following operation called?
<pre><code class="language-C#">var message = &quot;Hello&quot; + &quot;, Mark!&quot;;
</code></pre>

**(True or False)** The `StringBuilder` is derived from `System.String` and offers mutability.

(True or False) The <code>StringBuilder</code> is derived from <code>System.String</code> and offers mutability.
