So Windows can't deal with RAW tags.. great.. so one of these days I'm gonna have to answer someone who comes up to me about NFC usage in Windows and I'm gonna have to tell them to keep a spare Android device around to manage them... fun!!!
As for the second part I was just trying to do this
oProx.SubscribeForMessage("NDEF", Sub(oDev As Windows.Networking.Proximity.ProximityDevice,
oMsg As Windows.Networking.Proximity.ProximityMessage)
Dim results = Windows.Security.Cryptography.CryptographicBuffer.ConvertBinaryToString(Windows.Security.Cryptography.BinaryStringEncoding.Utf16LE, oMsg.Data)
InsertLog("Got NDEF Message :" & results)
End Sub)
The subscribe call fails immediately with a File Not Found Exception
