.NET is a popular free framework elaborated and maintained by Microsoft that allows building apps of any type — mobile, desktop, web, games, cloud, IoT, and so on. The framework has been constantly gaining popularity due to its object-oriented programming environment, the increased code and components reusability, high security, stability, and a wide range of available features.

According to the 2019 StackOverflow survey, .NET and .NET Core are the most used frameworks beyond web development, while ASP.NET is placed fourth in the list of the most popular web frameworks.

Not only developers take advantage of using this technology. .NET has been a choice of a big list of widely-known companies such as StackOverflow, Intel, Dell, and others. Therefore, we decided to compile a list of top .NET development companies your business can benefit from.
