Testing ClarifAI and seeing "The type or namespace name 'Clarifai' could not be found" in the Unity console

Question

I performed the following steps to test ClarifAI image recognition in a new project and am having issues. These are the steps I took:

• Created a new Unity 2020.3.8f1 project
• Created a test C# script called AItest and opened it in Visual Studio 2022
• Used the Nuget Package Manager to run 'Install-Package ClarifaiGrpc' (per https://github.com/Clarifai/clarifai-csharp-grpc) which ran ok.
• Added code (per instructions at https://github.com/Clarifai/clarifai-csharp-grpc)

Visual Studio gives no issues with the code, however, in the Unity console I see: 

 

Here is the code:

using UnityEngine;
using System;
using System.Collections.Generic;
using Clarifai.Api;
using Clarifai.Channels;
using Grpc.Core;
using StatusCode = Clarifai.Api.Status.StatusCode;
using UnityEngine.Profiling.Memory.Experimental;

public class AItest : MonoBehaviour
{
    void Start()
    {
        var client = new V2.V2Client(ClarifaiChannel.Grpc());

        var metadata = new Metadata
        {
            {"Authorization", "Key {YOUR_PERSONAL_TOKEN}"}
        };
    }
}

Usually, when I see that error, I also see underlines in the using statements but not this time. I also tried uninstalling and reinstalling ClarifaiGrpc but that didn't help.

I already have an API key and will replace YOUR_PERSONAL_TOKEN with it in the code when I can overcome these errors.

Any assistance to resolve this would be greatly appreciated, thank you.

I'm not sure nuget package are fully compatible with Unity? You may want to look at NuGet packages in Unity
