Bond.IO DLL error on latest version of Bing.Speech assembly
Version 2.0.2 of this installs Bond assemblies version 7.0.1, however when using "RecognizeAsync" it looks for version 22.214.171.124 of the Bond.IO.Dll which obviously doesn't exist. This is easily reproducible by taking the SpeechClientSample and updating the Microsoft.Speech.Bing nuget package to the latest 'Stable' build.
Bing Speech has been discontinued. For new development you should move to the new Custom Speech Service and the related SDK
