How to remove the .NET Core Runtime and SDK

Over time, as you install updated versions of the .NET Core runtime and SDK, you may want to remove outdated versions of .NET Core

from your machine. Removing older versions of the runtime may change the runtime chosen to run shared framework applications, as

detailed in the article on .

The behaviors and the runtime compatibility of .NET Core across updates enables safe removal of previous versions. .NET Core runtime

updates are compatible within a major version 'band' such as 1.x Additionally, newer releases of the .NET Core SDK generally

maintain the ability to build applications that target previous versions of the runtime in a compatible manner.

In general, you only need the latest SDK and latest patch version of the runtimes required for your application. Instances where retaining

older SDK or Runtime versions include maintaining -based applications. Unless your application has specific reasons for

earlier SDKs or runtimes, you may safely remove older versions.

Starting with .NET Core 2.1, the .NET CLI has options you can use to list the versions of the SDK and runtime that are installed on your

machine. Use to see the list of SDKs installed on your machine. Use to see the list of runtimes installed on your machine. The following

text shows typical output for Windows, macOS, or Linux:
