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

In my case all this methods didn't work. Finally I resolve this problem by uninstalling Microsoft.AspNet.Web.Optimization and WebGrease Packages via Package Manager, then I open my project file (.csproj) in notepad and delete all entries related to this two Packages, turn outs that there was problem. Finally I install this two packages via package manager again and run project. All work's fine now.
