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.

A non-generic type can’t inherit from a generic type.

A non-generic type can’t inherit from a generic type.

```C#
SomeClass instance = new SomeClass();
instance.StaticMethod();
```

```C#
(new SomeClass()).StaticMethod();
```

Which is the correct way to call a static method?

Which is the correct way to call a static method?

```C#
public static int CalculateSquare(int number)
{
}
```

```C#
private string GenerateSequence()
{
}
```

```C#
internal virtual void Link()
{
}
```

```C#
public decimal GetRemainingSum()
{
}
```

We can implicitly cast from `System.String` to `int`.

We can implicitly cast from <code>System.String</code> to <code>int</code>.

Explicit conversion is the only possible option here.

No casting is possible if there is no implicit conversion between types.

What can we do when there’s no implicit conversion between two user-defined types?

What can we do when there’s no implicit conversion between two user-defined types?

Create another abstract class and inherit from `SystemAccount`.

What isn’t possible with an abstract class called `SystemAccount`?

What isn’t possible with an abstract class called <code>SystemAccount</code>?

Both structs and interfaces support inheritance.

Which statement regarding inheritance in structs and interfaces is correct?

Which statement regarding inheritance in structs and interfaces is correct?
