Check the package source in the PackageManagerConsole Window. Change it to nuget.org from the dropdown, to install the package from the online repository.

I have faced same issue . I have followed below steps and it works for me.

Before Install-Package Microsoft.AspNet.WebApi.Cors. check the nuget.org link in package manager settings.

In Visual studio click Tools->NuGet Package Manager->Package Manager settings

verify by selecting a tree item

NuGet Package Manager -> Package Sources

"**https://www.nuget.org/api/v2**" is added or not. If not then add this by given any name and source as this url. then try again to install WebApi.Cors

Install-Package Microsoft.AspNet.WebApi.Cors
