The version you are installing 1.0.7 is different to the version 1.0.5 in the error message. I would open your .csproj file into a text editor and see if there is a reference to the 1.0.5 version which is not being used by the project.Matt Ward– Matt Ward2017-09-05 16:11:02 +00:00Commented Sep 5, 2017 at 16:11

Open Nuget Package Manager and pick "Unistall" on this package, than istall it again. If this does not help you do next:
- Unload project and remove all reference on this package from
.csprojfile - Remove reference on this package from
Web.config(orApp.config) if it there. - Remove reference from
packages.configfile - Install via nuget you package again.
Hope this helps you.

Right click solution in visual studio and select "Restore Nuget Packages", it will download the missing packages

Use the following command in the Package Manage Console:
Update-Package -reinstall -Project YourProjectName
It is by project, but this way is garanteed it works, at least in 100% of cases that happen to me.
