Can not compile on target 4.6.2 framework

[xmhealth]

My project target framework is .net framework 4.6.2, and I add InterSystems.Data.IRISClient, compile error:

Error CS1705 Assembly 'InterSystems.Data.IRISClient' with identity 'InterSystems.Data.IRISClient, Version=1.0.0.0, Culture=neutral, PublicKeyToken=ad350a26c4a4447c' uses 'System.Runtime, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' which has a higher version than referenced assembly 'System.Runtime' with identity 'System.Runtime, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
