Uninstall the current pack if you specifically need legacy targeting (not recommended). Pro tip: For modern development, migrate to
Very little in practice. The Targeting Pack (a smaller download) contains only the reference assemblies and tools for building. The Developer Pack includes the Targeting Pack plus the runtime for testing. For most developers, the Developer Pack is the right choice.
