System.MissingMethodException thrown from HidDevices.Enumerate

[AngusMcIntyre]

Hi Mike and friends,

I recently upgraded my Nuget package from 3.2.23 to 3.2.29 and am receiving a MissingMethodException when enumerating my device,

Exception content

System.MissingMethodException was unhandled
  HResult=-2146233069
  Message=Method not found: 'Int32 System.Runtime.InteropServices.Marshal.SizeOf(!!0)'.

  InnerException:

Environment

• The exception happens with all overloads and is not present in version 3.2.28.
• I have .NET Framework 4.5 installed but no higher that I can see.
• Operating System: Windows 7 x64

I imagine the .NET version is the problem but I wanted to let you know. I'm fairly sure Nuget shouldn't have let me add it to me project!

I'm not sure how to fix this, but it seems like the system is failing to create a new instance of NativeMethods.SP_DEVICE_INTERFACE_DATA, so the call to SizeOf is passed a null pointer (or something else that evaluates to !!0). Why it would throw this exception instead of the ArgumentNullException expected from the docs is anyone's guess. What OS and architecture are you targeting?

[AngusMcIntyre]

@amullins83 I've edited in the OS an architecture. A silly omission in the first place!

Installing the latest version of .NET help me with this problem.
