Thank you for contacting us and sorry for the late reply.
WPF NuGet Package provides support for .Net Framework 4.0 and .Net Framework 4.5, but for "NoXaml" assemblies only
. You could get more information on NoXAML asemblies from our online help: link
If you prefer to use XAML assemblies, you could use the msi installer or the hotfix, containing only the Dlls.
Let me know if that helps.
