The .NET Framework 4 Targeting Pack is a part of the .NET Framework 4 software development kit (SDK). It provides the necessary libraries, tools, and documentation for developers to create .NET Framework 4 applications. This targeting pack ensures that applications are built with the correct libraries and dependencies, enabling them to run on .NET Framework 4.
Note: In recent versions of Visual Studio 2019 and 2022, Microsoft has consolidated older targeting packs. You may need to install the ".NET Framework 4.8 Targeting Pack" to gain access to older versions via multi-targeting, or install the "4.0 targeting pack" specifically if listed. microsoft .net framework 4 targeting pack download
