This change modifies the target framework from TargetFrameworks (plural) to TargetFramework (singular) and adds a specific Windows version requirement. This could be a breaking change for consumers who were previously able to target multiple frameworks or older Windows versions. Please alert reviewers that this is potentially a breaking change.
