System.IO.FileNotFoundException: 'Could not load file or assembly 'System.ServiceModel.Security, Version=4.0.3.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.'

Ported my library to .NET Standard
Referenced it in a 4.6.2 .NET project.
If I use DnsEndpointIdentity in the library I get the exception.
Even though it is supposedly compatible?
Tried referencing the System.IdentityModel and System.ServiceModel.Security dlls but it just doesn't work.
Any idea which dll needs to be referenced in a .NET project for this to work?
Perhaps something needs to be added to the app.config to make it use the 4.6.2 dlls when looking for this assembly reference?

When you say you reference the System.ServiceModel.Security dll how did you do that? I think what you need to do is reference the System..ServiceModel.Security nuget package (https://www.nuget.org/packages/System.ServiceModel.Security/).
