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 looks like you have reference to older (1.0.0.0?) version of assembly (assuming current version is 1.3.0.0). In this case you need assembly redirect in web.config or better yet recompile your binaries to use latest version.

Another possiblity if latest version shares the same assembly version as old one (1.0.0.0) you need to recompile your code to use the right assembly and make sure correct copy is used (check GAC for wrong one, use fuslogv to investigate what exact file caused the error).
