NuGet also uses multi-targeting concepts. A single NuGet package can contain multiple versions of a library, each in a folder named for the target framework (e.g., net40 , net45 , net48 ). When installing such a package into a project that targets .NET Framework 4.6, NuGet automatically selects the assembly from the net45 folder, because that is the highest available version that is still less than or equal to 4.6.

: These were cumulative updates that added new APIs, particularly for Windows Workflow Foundation (WF) and Windows Communication Foundation (WCF) scenarios. They were released as separate targeting packs, allowing developers to adopt specific feature sets as needed.
