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 type can implement only one interface.

(True or False) A type can implement only one interface.

**(True or False)** If a class inherits from another class, then it can’t implement any interfaces, because multiple inheritance isn’t allowed.

(True or False) If a class inherits from another class, then it can’t implement any interfaces, because multiple inheritance isn’t allowed.

Consider the following code:

```C#
public interface IDisposable { }

public interface ICloneable { }

public interface ISerializable : IDisposable, ICloneable
{
}

public class MyClass : ISerializable { }
```

How many interfaces does `MyClass` have to implement?


Consider the following code:
<pre><code class="language-C#">public interface IDisposable { }

public interface ICloneable { }

public interface ISerializable : IDisposable, ICloneable
{
}

public class MyClass : ISerializable { }
</code></pre>
How many interfaces does <code>MyClass</code> have to implement?

Consider the following code:

```C#
public interface ICloneable<T>
{
 T Clone();
}

public class MyClass : ICloneable<string>
{
}
```

What’s the return type of the `Clone()` method of `MyClass`?

Consider the following code:
<pre><code class="language-C#">public interface ICloneable&lt;T&gt;
{
 T Clone();
}

public class MyClass : ICloneable&lt;string&gt;
{
}
</code></pre>
What’s the return type of the <code>Clone()</code> method of <code>MyClass</code>?
