Frequently asked questions

What is .NET?

The .NET framework developed by Microsoft allows a variety of programming languages to build dynamic web applications and web services. While ASP.NET only caters to web applications, the broader .NET framework supports desktop, mobile, and much more.

Why use .NET for web development?

  • Rapid Development – Thanks to powerful tools powered by Microsoft such as Visual Studio, the .NET framework enables the quick development, deployment and management of applications.
  • Easy integration – .NET is a flexible software framework that allows a diversity of integrations, from existing web services to business applications written, the most popular being C#.
  • Robust framework – By using existing software development frameworks and features, .NET is able to produce high quality, reliable apps with built-in security features. As a strongly-typed language, it also minimises errors.
  • Well supported  – Because it is powered by Microsoft, .NET is extremely well supported. The frequent updates are backward-compatible, which spares developers from manually resolving breaking changes.
