You need to run WCF in ASP.Net compat mode to get access to HttpContext. Not sure why you need it though because then you can only run the WCF services on IIS in asp.net compat mode and not within a different hosting environment like a windows service.

more information here: https://learn.microsoft.com/en-us/dotnet/framework/wcf/feature-details/wcf-services-and-aspnet which also tells you about contexts you should be using instead of HttpContext
