.NET is a composite of two famous languages, VB.NET and C#. To kick-start a career on this platform, .NET developers can learn any of these languages. Both these languages can accomplish the same functions. .NET developers can select any of them at their convenience. In this ASP.NET Tutorial, we will explore how to become an ASP.NET developer. Let’s first understand what ASP.NET Developers do exactly.

What do ASP.NET Developers do?

.NET Developers are those technical professionals who can develop software applications using the .NET infrastructure provided by Microsoft. They can create web, mobile, and desktop applications that are secure and faster. Their job profile involves the role of developing software applications through the .NET framework. It is known that .NET developers are accountable for the entire development process, ranging from writing the code to storing, testing, and finding errors. Hence, they can create an interactive application. Before diving deep into the details of how to become an ASP.NET developer, let's see what ASP.NET developers actually do.

Prerequisites

1. Education Qualifications

The foremost and crucial step to becoming an ASP.NET developer is to get the relevant educational qualifications. For this job role, a bachelor’s degree in Computer science is required. But many companies don’t prioritize a degree. A degree in Computer science helps to cover the fundamentals of coding and programming languages. If you don’t have a technical background, then you can study the fundamental concepts of the .NET development platform and the framework.

2. Learn the basics

The first step when it comes to learning the basics is to learn the C# programming language. C# is the programming language that is used by all .NET developers. It is one of the preferred languages by all .NET developers. Moreover, it is rated as the simplest to learn and expressive programming language. Fundamental C# (.NET) skills you need to understand are variables, data types, loops, conditionals, classes, objects, fields and properties, methods, LINQ, interfaces, polymorphism, inheritance, and encapsulation

The next important basic skill is the Visual Studio IDE. To become proficient with the .NET platform, you should work on acquiring fundamental knowledge on .NET Core, .NET Framework, .NET Standard, and Xamarin.Mono. Since .NET is a multilingual platform, it allows you to become proficient in multiple programming languages like C++, Java, Python, and more. Whichever programming language you choose to learn, make sure to master it with proficiency.

Other skills a .NET developer must master include front-end technologies like HTML, CSS, JavaScript, etc., Cloud computing, Machine Learning, web development, and communication skills. It is advisable to focus on learning various courses and certifications for these skills. Moreover, the curriculum of such specialization courses expands your perspectives.

3 . Important Skills

Important skills ASP.NET Developers should learn:

• C# programming language
• .NET Basics
• SQL database
• NET Core
• Basics of data types, variables, objects, methods, loops, LINQ, etc.
• Understanding of SQL Server, ASP.NET framework, and architectural patterns (like MVC)
• Knowledge of minimum one .NET languages (C#, Visual Basic .NET) and HTML5/CSS3
• Understanding of architecture styles/APIs (REST, RPC)
• Understanding of Agile methodologies
• Troubleshooting and communication skills

Other skills ASP.NET Developers should learn

• .NET
• MVC
• SQL Server
• Visual Studio
• JavaScript
• jQuery
• CSS
• Entity Framework
• Web API
• LINQ
• Frontend JS Frameworks: Angular/React

4. Selection of IDE

The next important consideration in becoming an ASP.NET developer is to determine which IDE to use. Visual Studio IDE is the program where majority of the .NET developers write C# code. Note that Visual Studio for Windows is free for personal use and till now, it is the best IDE for the .NET developers. Also, you can download Visual Studio for Mac.

For using .NET development on Linux or Mac, it is recommended to use the Rider IDE (from Jetbrains). This is because it has several features as Visual Studio. Moreover, it comes with an integrated tool i.e. Reshaper, that helps you to write expressive and clean C# code. Though it is a recommended IDE for .NET, it is possible to code with .NET through Visual Studio Code IDE (because it is a lightweight version of the Visual Studio).

5. Learn SQL

Another prominent aspect to focus on when becoming an ASP.NET developer is learning SQL (Structured Query Language). It is widely used for querying databases to retrieve data. The most frequently used database by .NET developers is the Microsoft SQL Server which is available for personal and free use.

If you want to learn SQL Server on Windows OS, you would benefit from an easy-to-navigate user interface for running SQL queries. On the other hand, if you are using a Mac or Linux, it may be bit challenging to install SQL server because you have to use the Docker containers.

You may need to install a Windows virtual machine and then use SQL Server. Note that Microsoft SQL Server is the most frequently used database in the .NET environments, but you can also utilize other database systems, like MySQL or PostgreSQL.

6. Selection of Specialty

.NET platform facilitates application development for mobile, desktop, web, and gaming platforms that are assimilated with machine learning and Cloud computing features. So, you need to explore your interests. Subsequently, you need to focus on mastering the preferred platform.

You cannot become a .NET developer without selecting the development direction. If you are quite a beginner to web development, then you can start learning web development by working with ASP.NET Core and MVC.API, and Blazor. For Cloud development, you can work with Microsoft Azure. For mobile development, you need to work with Xamarin. When it comes to desktop development, you would be working with WinForms/WPF/UWP/ Xamarin.Forms. For Microservices, you need to work with Docker and .NET Core. When it comes to gaming, you would be working with MonoGame or Unity, or CRYENGINE. For Machine Learning, you would be working with Apache Spark, ML.NET, or Cognitive Services, or Azure Machine Learning.

7. Learn Web Development

Most people willing to become an ASP.NET developer are inclined towards learning web development. For creating web-based applications on the .NET platform, it is necessary to learn ASP.NET Core. This is because it is cross-platform and a future technology for the web. Usually, ASP.NET developers can work on WebAPI and MVC-based web applications. In recent times, MVC-based web applications are obsolete because every web page are reloaded whenever you navigate across the website. On the other hand, WebAPI-based applications typically work with SPAs (Single-page applications) like React or Angular. Whenever you browse these types of apps, there will be no reloading of pages. Usually, ASP.NET developers are not responsible for SPAs. They must know WebAPI and MVC.

8. Learn ASP.NET Core

A reliable course is helpful to learn ASP.NET Core. This can be done with the use of LinkedIn Learning. Since ASP.NET Core is a broad term, watching only a single course of one or two hours will not be useful. It is recommended to take an entire learning path.

9. Learn Cloud Development

One of the most desired skills in the present and future is Cloud development. Typically, Microsoft developers opt for Azure in the form of their key cloud platform. The reason is it is built by .NET developers. You can use Google Cloud or Amazon AWS as per your preference. Plenty of companies have migrated their technologies from on-premise to Azure. It is scalable and the most contemporary approach to running the applications. Security is also one of the essential concerns for every company, and in the cloud, your applications will be much safer than on-premises. A decent .NET developer must learn Microsoft Azure because it would assist them in some of their roles and responsibilities.

10. Other things you need to learn for .NET

As you dive into the learning path for becoming an ASP.NET developer, you will encounter a lot of things. It is not possible to discuss all of them. Some additional concepts you need to learn to become an ASP.NET developer are as follows-

• NuGet Packages
• CI/CD pipeline
• Azure Services
• Visual Studio

Summary

Mastering the skills discussed above can transform you into a proficient ASP.NET developer. Presently, ASP.NET and C# are among those technologies that are no longer based only on Windows. They can be executed on Linux servers as well. However, to simplify development and up your game, learn the intricacies of ASP.NET from the ASP.NET Core Training Certification with ScholarHat by Dot Net Tricks and level up as an ASP.NET developer.
