What is .NET?
• .NET is an open source developer platform, created by Microsoft, for
building many different types of applications.
• .NET is a free, cross-platform, open source developer platform for
building many different types of applications.
• With .NET, you can use multiple languages, editors, and libraries to
build for web, mobile, desktop, games, and IoT.

Languages
• You can write .NET apps in C#, F#, or Visual Basic.
• C# is a simple, modern, object-oriented, and type-safe programming
language.
• F# is a cross-platform, open-source, functional programming language for
.NET. It also includes object-oriented and imperative programming.
• Visual Basic is an approachable language with a simple syntax for building
type-safe, object-oriented apps.

Languages
• C#
• C# (pronounced "C sharp") is a
simple, modern, object-oriented,
and type-safe programming
language.
• Its roots in the C family of
languages makes C# immediately
familiar to C, C++, Java, and
JavaScript programmers.

Cross Platform
• Whether you're working in C#, F#, or Visual Basic, your code will run
natively on any compatible OS. Different .NET implementations
handle the heavy lifting for you:
• .NET Core is a cross-platform .NET implementation for websites, servers, and
console apps on Windows, Linux, and macOS.
• .NET Framework supports websites, services, desktop apps, and more on
Windows.
• Xamarin/Mono is a .NET implementation for running apps on all the major
mobile operating systems.

Libraries
• To extend functionality, Microsoft and others maintain a healthy
package ecosystem built on .NET Standard.
• NuGet is a package manager built specifically for .NET that contains over
90,000 packages.

What is ASP.NET?
• ASP.NET is an open source web framework, created by Microsoft, for
building modern web apps and services with .NET.
• ASP.NET is cross platform and runs on Windows, Linux, macOS, and
Docker.

ASP.NET extends .NET
• ASP.NET extends the .NET platform with tools and libraries specifically
for building web apps.
• These are some things that ASP.NET adds to the .NET platform:
• Base framework for processing web requests in C# or F#
• Web-page templating syntax, known as Razor, for building dynamic web pages
using C#
• Libraries for common web patterns, such as Model View Controller (MVC)
• Authentication system that includes libraries, a database, and template pages
for handling logins, including multi-factor authentication and external
authentication with Google, Twitter, and more.
• Editor extensions to provide syntax highlighting, code completion, and other
functionality specifically for developing web pages

Back-end code
• When using ASP.NET your back-end code, such as business logic and
data access, is written using C#, F#, or Visual Basic.
• Because ASP.NET extends .NET, you can use the large ecosystem of
packages and libraries available to all .NET developers. You can also
author your own libraries that are shared between any applications
written on the .NET platform.

Dynamic pages using C#, HTML, CSS and
JavaScript
• Razor provides a syntax for creating
dynamic web pages using HTML
and C#. Your C# code is evaluated
on the server and the resulting
HTML content is sent to the user.
• Code that executes client-side is
written in JavaScript. ASP.NET
integrates with JavaScript
frameworks and includes preconfigured
templates for single
page app (SPA) frameworks like
React and Angular.

What is ASP.NET Core?
• If you use ASP.NET, you'll soon come across the term ASP.NET Core.
• ASP.NET Core is the open-source and cross-platform version of
ASP.NET. You should use ASP.NET Core for all new applications.
• The Windows-only versions of ASP.NET, that existed before ASP.NET
Core, is typically just referred to as ASP.NET. The majority of
innovation occurs in ASP.NET Core, but other versions continue to
receive minor updates and bug-fixes.
