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

It's a problem with Microsoft.AspNet.Web.Optimization (Optimise moving forward).

You need to downgrade WebGrease by uninstalling Optimise and removing any WebGrease assembly redirects from web.config.

Then reinstall Optimise and make sure you don't upgrade WebGrease.

It's a quick fix but it got my build working!
