Where is AsymmetricSecurityBindingElement in .NetStandard2.0?

Question

I'm upgrading my class library from Net Framework 4.7.1 to NetStandard 2.0 and I have encountered a problem because I can't seem to find:

1. AsymmetricSecurityBindingElement
2. X509SecurityTokenParameters

I have added the following packages:

<PackageReference Include="System.ServiceModel.Http" Version="4.5.3" />
<PackageReference Include="System.ServiceModel.Primitives" Version="4.5.3" />
<PackageReference Include="System.ServiceModel.Security" Version="4.5.3" />

What additional packages to I need?

根据apisof.net参考， AsymmetricSecurityBindingElement在.net标准2.0中不可用，仅在完整的.net Framework和Mono中可用。
