Upgrading WebGrease to version 1.3.0 gets me error

Question

While upgrading WebGrease to version 1.3.0 gets me error:

Could not load file or assembly \'WebGrease, Version=1.0.0.0, Cult

Answer 1

Thanks to @roadsunknown. My configuration got hosed after my host machine froze, thus causing my VM to not shutdown properly. To resolve this I uninstalled Microsoft.AspNet.Web.Optimization through NuGet, then had to remove the reference to WebGrease in packages.config, and finally reinstalled Microsoft.AspNet.Web.Optimization through NuGet.
