What’s the difference between .NET, .NET Core, and ASP.NET?

The difference might seem subtle, but it exists:

  • .NET is the overall Microsoft development platform. It includes tools, runtime, and libraries for building various types of applications.
  • .NET Core, which is now unified under modern .NET versions, was introduced as a cross-platform framework designed for cloud and microservices-based applications.
  • ASP.NET is a web development framework within the .NET ecosystem. It’s used specifically for building web applications, APIs, and dynamic websites.

Today, modern .NET versions unify these technologies into a single platform. Whether it’s ASP.NET development services you’re looking for or .NET Core, our company will help you accelerate the implementation of a solution to address your goals.
