As an obsolete concept, the .NET Execution Environment contains the code required to bootstrap and run an application. This includes things like the compilation system, SDK tools, and the native CLR hosts.

Note that DNX is no longer an active term used in .NET Core ecosystem, and you should migrate to .NET Core CLI.

The .NET Execution Environment contains the code required to bootstrap and run an application. This includes things like the compilation system, SDK tools, and the native CLR hosts.

Goals

  • Create a new development experience that enables a quick development workflow (change code and run)
  • Have the ability to create a cached version of your application's dependencies ("compilation")
  • Expose metadata about the runtime for others to query

Principles

  • NuGet all the things
  • There is no such thing as "design time" (blur the lines between compilation and loading)
  • Dependencies are always described as what not where (there's no such thing as a project/nuget/assembly reference)
