Which nuget package has ILanguageServiceClient?

I checked both Microsoft.CodeAnalysis, https://video2.skills-academy.com/en-us/dotnet/api/microsoft.codeanalysis?view=roslyn-dotnet-4.9.0 and Azure.AI.Language but none of them has ILanguageServiceClient

I found this pseudo code from google to access and interact with Azure language studio cognitive service. Is there any other way to replace ILanguageServiceClient?

    public class DevOpsBot : ActivityHandler
    {
        private readonly ILanguageServiceClient _languageServiceClient;

        public DevOpsBot(ILanguageServiceClient languageServiceClient)
        {  
            _languageServiceClient = languageServiceClient; 
            
        }

        protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
        {
            var text = turnContext.Activity.Text;
            var prediction = await _languageServiceClient.PredictionAsync(text);
            switch (prediction.TopIntent)
            {
                case "A";
#                  do something here;
                    break;
                case "B";
#                  do something here;
                    break;
                case "C";
#                  do something here;
                    break;
                default:
            }
        }
}

Hello @Pham, Andy,

About your update:

I checked both Microsoft.CodeAnalysis, https://video2.skills-academy.com/en-us/dotnet/api/microsoft.codeanalysis?view=roslyn-dotnet-4.9.0 and Azure.AI.Language but none of them has ILanguageServiceClient

You cannot get the ILanguageServiceClient interface directly in the NuGet package Microsoft.CodeAnalysis.Workspaces needless to say Microsoft.CodeAnalysis. However, the Microsoft.CodeAnalysis.Workspaces.Common in 4.7.0 and above or Microsoft.CodeAnalysis.Host in 4.9.2 and below packages, which is a shared package used by the .NET Compiler Platform (Roslyn), provides support for analyzing C# projects and solutions.

This is the details:

• Namespace:Microsoft.CodeAnalysis.Host
• Assembly:Microsoft.CodeAnalysis.Workspaces.dll
• Package:Microsoft.CodeAnalysis.Workspaces.Common v4.7.0
• Source:ILanguageService.cs

Check out this link:

• https://video2.skills-academy.com/en-us/dotnet/api/microsoft.codeanalysis.host.ilanguageservice?view=roslyn-dotnet-4.7.0
• https://www.nuget.org/packages/Microsoft.CodeAnalysis.Workspaces.Common/

If you're working Azure language service, you can do as @romungi-MSFT suggested. Though, I haven't check it out except for .net

Sina, thank you for your quick response. I just checked and tried the ILanguageService. It does not have predict for text entity extraction method.

var prediction = await _languageServiceClient.PredictionAsync(text);
