 This extension provides a unified way for other extensions like the [C#] and [C# Dev Kit] extensions to install local versions of the .NET Runtime, and machine-wide versions of the .NET SDK. Those extensions tell the .NET Install Tool when they would like a .NET SDK to be on the machine, and we install one for them if there's not already one that matches the SDK they need to run properly. Users can also install the .NET SDK themselves by reading below.

 This VSCode extension allows acquisition of a local copy of the .NET SDK. While originally developed and intended to be used as part of the [.NET Coding Pack], this extension can be used by other extensions like C# DevKit, Polyglot Notebooks, and others to ensure that a .NET SDK is available on the user's machine. This can be useful when another extension needs to make use of the .NET Toolchain to compile or run code.
