On .NET Framework The SDK does not correctly locate the Yubico.NativeShims.dll on 32 bit processes.

When loading the SDK and trying to enumerate devices using the FindAll or FindByTransport methods. You will get a System.BadImageFormatException HResult=0x8007000B Message=An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) Source=Yubico.Core

NETFramework apps are 32bit processes by default. The workaround is to set your project to be 64 bit by using <Prefer32Bit>false</Prefer32Bit> in your csproj.
