The editor apparently didn't forward your annotations to my questions. Can you send another post that includes your answers to the questions above?
Host Platform OS: Windows 10
Target Device Model: FX7500
Device Firmware Version: 188.8.131.52
Visual Studio Version: VS 2015
SDK Version: No SDK just using the Symbol.RFID3.dll directly.
EMDK Version: .Net 2.9
Connection Type: Ethernet
The issue is with .NET 4.0+ and Windows 8/10. The Symbol.RFID3.Host.dll works with .NET 4.0+ on Windows 7. The dll also works for versions of .NET up to 3.5 as you've previously observed. I'll look in to any work around for this scenario.
