Could not load file or assembly 'System.Net.Security - When running ASP Core app on Nano Server

Hi there,

I'm getting the following error when running my app on Nano server using  coreclr x64 rc1-final. 

"Could not load file or assembly 'System.Net.Security, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified"

Any ideas why this might be?

Nick,
