Need assistance on calling Azure TTS from WCF


Hello,

I am receiving this error when calling Azure TTS from a WCF Web service:

{"Exception with an error code: 0x38 (SPXERR_AUDIO_SYS_LIBRARY_NOT_FOUND)"} System.Exception {System.ApplicationException}

The Microsoft.CognitiveServices.Speech.extension.audio.sys.dll is located in my Azure class library and WCF Bin folder.

Any suggestions?

Hello,

Thanks for responding.

The error was solved by rebooting the machine.

I updated VS 2019 in order to use WCF.
