What NuGet Package I need to add to a WebForms project to get IExceptionLogger class visible for global error handling?

I have a Webforms website in .Net 4.5, to which I have added the NuGet package for 'Microsoft ASP.Net Web API 2.2'.

But even though I can get the Web API methods to work, I am unable to implement global exception handling since the class IExceptionHandler is not visible. Perhaps, it resides in a dll that is not added as part of 'Microsoft ASP.Net Web API 2.2'.
