Could not load file or assembly Bond.IO

问题

Using Microsoft.Bing.Speech nuget package and Net Framework 4.6.1 I'm having this exception when calling RecognizeAsync()

Could not load file or assembly 'Bond.IO, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

My code:

public static async Task SpeechToTextStreamPO(Stream audioStream, string textResult)
    {
        var subscriptionKey = ConfigurationManager.AppSettings["BingSpeechSubscriptionKey"];

        Uri ShortPhraseUrl = new Uri(@"wss://speech.platform.bing.com/api/service/recognition");
        Uri LongDictationUrl = new Uri(@"wss://speech.platform.bing.com/api/service/recognition/continuous");
        CancellationTokenSource cts = new CancellationTokenSource();

        var preferences = new Microsoft.Bing.Speech.Preferences("en-IN", ShortPhraseUrl, new CognitiveServicesAuthorizationProvider(subscriptionKey));

        // Create a a speech client
        using (var speechClient = new SpeechClient(preferences))
        {
            speechClient.SubscribeToRecognitionResult(async (recognitionResult) =>
            {
                if (recognitionResult.RecognitionStatus == Microsoft.Bing.Speech.RecognitionStatus.Success)
                {
                    textResult = recognitionResult.Phrases[0].DisplayText;
                }
            });

            var deviceMetadata = new DeviceMetadata(DeviceType.Near, DeviceFamily.Mobile, NetworkType.CellLTE, OsName.Android, "1607", "Dell", "T3600");
            var applicationMetadata = new ApplicationMetadata("SampleApp", "1.0.0");
            var requestMetadata = new RequestMetadata(Guid.NewGuid(), deviceMetadata, applicationMetadata, "SampleAppService");

            await speechClient.RecognizeAsync(new SpeechInput(audioStream, requestMetadata), cts.Token).ConfigureAwait(false);}
    }

I've tried installing different versions and changing version numbers in .csproj but I can't make it work.

Any ideas?

it worked for me with changing Bond.Core.CSharp package to 4.2.0
