Who is a .NET Developer?

.Net Developer is a technical professional or developer who mainly works on designing and creating software applications using the .NET Platform technologies. The .NET platform is compatible with languages like C#, F#, VB.Net, etc. So, as a .Net Developer, we can use any of the languages supported by the framework to develop the application. However, most Developers mainly prefer C# as their preferred language for building applications.

.Net Developers are mainly employed in systems and software houses, either in telecommunications, information technology companies, engineering offices for technical planning, or computer service providers. However, they can also work in various positions, such as IT Research and development facilities or the IT departments of companies in different sectors of the industry.

As a .Net Developer, we should know the below items –

• Programming Languages and Paradigms
• Code Structure, architecture, and system design.
• Development Platform or frameworks along with different stacks and tools.
• Handling database operations.
• Test the development to produce an error-free application.
• Analytical thinking.
• Communication.

8 Skills Required to Become a .NET Developer

If you want to start your career as a .Net Developer, you need to know some mandatory skills required for this job role. For this job role, both technical skills and soft skills are needed.

1. .NET Framework and .NET Core: Learn about Common Language Runtime (CLR), Base Class Library (BCL), and core functionalities. Understand the differences between .NET Framework and .NET Core, and learn to leverage their features effectively.
2. ASP.NET and ASP.NET Core: Understand concepts like MVC (Model-View-Controller), Web API, routing, middleware, authentication, and authorization. Familiarity with front-end technologies like HTML, CSS, JavaScript, and client-side frameworks (e.g., Angular, React) is also beneficial.
3. Desktop Application Development: For this, learn frameworks like Windows Forms and WPF (Windows Presentation Foundation). Then, explore concepts related to user interface (UI) design, data binding, controls, events, and MVVM (Model-View-ViewModel) architecture.
4. Database Management: Become proficient in database management systems like SQL Server, MySQL, PostgreSQL, or SQLite. Understand database design principles, SQL queries, stored procedures, indexing, normalization, and transaction management.
5. Version Control Systems: Learn how to use version control systems like Git for managing source code, collaborating with team members, and tracking changes across projects.
6. Testing and Debugging: Develop skills in unit testing, integration testing, and automated testing techniques using frameworks like NUnit, xUnit, or MSTest.
7. Deployment and DevOps: Understand the basics of deployment pipelines, continuous integration, and continuous deployment (CI/CD) practices. Learn to automate build, test, and deployment processes using tools like Azure DevOps, Jenkins, TeamCity, or GitHub Actions.
8. Problem-Solving and Critical Thinking: Develop strong problem-solving skills and the ability to analyze requirements, identify potential solutions, and make informed decisions.

Many companies want MCSD-certified developers for the following reasons:

• The certification process is created and maintained by Microsoft.
• Developers who pass the certification once need to recertify after two years to keep up with the latest .NET skills.
• It is a challenging but competent program that genuinely justifies the certification level.

Soft Skills

• Communication
• Problem–Solving Skills
• Time Management
• Team Building Skills
