How to Learn .NET
If you’re looking for a developer platform that can help you create anything, from apps and games to Internet of Things applications, look no further than Microsoft’s .NET.
.NET is a developer platform with tools, programming languages, and libraries for building many types of applications. It is used in many industries and is a very valuable skill to learn if you want to become a developer. In this article, we’ll explore how to get started with learning this technology.
What Is .NET?
Created by Microsoft, .NET (pronounced “dot net”), is a platform of collected technologies for building apps on Windows, Linux, macOS, iOS, Android, and other operating systems.
These technologies include .NET Framework, a software development framework for running websites on a Windows operating system; .NET Core, a cross-platform implementation for running apps and services on other operating systems besides Windows; and Xamarin/Mono, a .NET implementation for running apps on all major operating systems, including mobile.
When you are building applications with .NET, you will need to use C#, C++/CLI (a version of C++), Cobol, F#, or Visual Basic. C# , a programming language created by Microsoft, is a great beginning language to learn. Learning both C# and .NET is a great idea if you are transitioning into a tech career.
What Is .NET Used For?
.NET has many features. With .NET, you can:
- Build web and desktop apps and games. .NET is a flexible platform. Projects by users who posted on BuiltWithDot.Net include a YouTube downloader, an online pet adoption community, a desktop space adventure game, and an app for tracking invoices.
- Cloud services. Combined with Microsoft’s Azure , a cloud services platform, you can host your .NET applications in the cloud. And with .NET Core, you can quickly build and deploy .NET Core applications on Google Cloud .
- Machine Learning. You can easily integrate machine learning functionality into your .NET apps with Microsoft’s ML.NET . Add vision algorithms, speech processing, and predictive models to your apps. Companies that use ML.NET include SigParser, which predicts whether an email sender is a person or an automated system; Williams Mullen, a law firm that uses ML.NET for document classification; and Scancam, a device that detects fuel theft.
- Internet of Things (IoT) . .NET supports hundreds of sensors, displays, and input devices. Some of these devices include temperature and humidity sensors, accelerometers, and gas sensors. With Microsoft’s open source library for IoT , you can build applications that can run on platforms like Raspberry Pi.
There are many companies that use .NET. These include Accenture, Stack Overflow, Trustpilot (a customer reviews website), and Paralect (a digital product engineering company).
Learning .NET is a great idea if you want to build software. .NET is a popular platform. According to
Stack Overflow’s 2020 Developer Survey
, .NET came in second in the category Other Frameworks, Libraries and Tools. Moreover, .NET Core came in third.

C# is a common language to use with .NET, so you will need to learn it. There are many resources available to learn this programming language, like this short tutorial from Microsoft for building .NET applications with C# .
How Long Does It Take to Learn .NET?
If you already know one of the languages compatible with .NET—such as C#, F#, or Visual Basic—it will take you two to three months to learn to use this platform professionally. If you don’t know any of these languages, you will need to learn one first.
C# is a great language to learn
for web development.
You should also know how to use Visual Studio, which is the IDE (Integrated Development Environment) that you will use to build projects with .NET.
How to Learn .NET: Step-by-Step
Assuming that you already know one of the programming languages used with .NET, here are some big-picture steps that you can take to learn this technology.
- Learn C# or another language compatible with .NET. In order to use the .NET developer platform, you should at least know the basics of one of its compatible programming languages, such as C#, C++/CLI,, Cobol, F#, or Visual Basic.
- Decide which specific .NET technology you want to learn first. There are several tools in the .NET platform, including .NET Core, .NET Framework, and .NET for mobile, such as Xamarin and Mono. Think about what your development needs and interests are as you are making your decision.
- Download the Community version of Visual Studio Code. Visual Studio Code is the IDE you will use for your .NET projects.
- Download the version of .NET you want. You can download the version of .NET that you want for free.
- Experiment with .NET tutorials. You can get started with .NET with this Hello World Tutorial , and there are many other .NET tutorials that you can try out.
- Learn more with a course or book. Check out the courses, books, and other resources listed below to grow your skills further.
The Best .NET Courses
Taking a course can help you practice your skills. Keep in mind that you should know C# and how to use Visual Studio Code before you start learning .NET.
