The Best of February 2026Looking for a top ASP development company in the United Kingdom?
Microsoft developed ASP.NET in 2002 as an open-source and server-side web development framework. It supports multiple programming languages include HTML, C#, F#, C++, and Visual Basic Net.
When hiring an ASP.NET developer, consider the specialties and years of experience needed for your project. Since the ASP.NET framework supports more than one programming language, your developer should have experience not only with ASP but also with your website's development languages. Beginner ASP.NET developers may be familiar with .NET, C#, HTML, and CSS, while more advanced developers will be familiar with .NET, additional programming languages, and development methodologies like Agile.
