    TargetFrameworks is used to convey that a project targets multiple frameworks.  Traversal does not support multi-targeting
    but having this property set to a value can confuse NuGet leading to errors.  Setting the property to empty fixes an issue
    where a user unknowningly sets it, breaking restore.  See also: https://github.com/microsoft/MSBuildSdks/issues/196
