.net-core Components and Versioning in .NET Core Selecting Versions
Example
It's possible to have multiple .NET Core SDKs and Runtimes available on disk. You can select the versions for each separately.
To select the version of the SDK to use, use global.json.
To select the version of the shared framework to use, target the specified framwork in the .csproj file (or project.json if you are still using that).
