Issues with .NET 4.7.2

I am getting when trying to call: var connection = Connection.Create(Kraken_Key, Kraken_Secret);

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