I have a .NET Core xUnit project. I'm trying to call a WCF service from it but get the following exception:
System.InvalidOperationException occurred HResult=0x80131509 Message=An error occurred while loading attribute 'ServiceContractAttribute' on type 'IMyContract'. Please see InnerException for more details. Inner Exception 1: FileNotFoundException: Could not load file or assembly 'System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified. It works with a Framework 4.7 project with the same Nuget Package System.ServiceModel.Http.4.3.0.

Microsoft has made available the relevant assemblies as packages on NuGet now.
System.ServiceModel.Primitives is the base package; add the others if necessary to your project.
