Resolution Note (2019.2.X):
Remove "System.Security.dll" from csc.rsp and only use it in the "mcs.rsp".
The "csc.rsp" is used specifically for UWP which builds against a specific set of .NET libraries via the Microsoft.NETCore.UniversalWindowsPlatform NuGet package. These libraries are a subset of the .NET 4.6 Framework and exclude certain assemblies/APIs, with "System.Security.dll" being one of them. So, if you specify this assembly in "csc.rsp" you'll receive a compiler error. Note that "System.Net.Http.dll" is present in .NET library package and so it works fine.
