As a workaround to this i created the Xwt-Alt NuGet package so that i could add XWT to my projects.
Why the name, Xwt-Alt (Alternative)? It's because I am not a direct developer for XWT, however I do use it and need to make sure applications are up to date with the most stable release of XWT. There are no changes to XWT other than the name, so when the official NuGet package is created it can be used in its place.
Currently Xwt-Alt is on NuGet's staging server & will be ported over to the main site very shortly. Hope this helps out.
As an FYI, the project is hosted on GitHub:
