Problem with YieldTask + FirebaseAuth

Unity Engine
1

Hello guys,

i finnaly have the time to work on my project again. After buying an asset in Unity Store i had to upgrade Unity to 2020.1.6f1 in order to use it.

Now i have an error on a script for logging in using Firebase Authentication.

public void SignUp(string username, string email, string password)
    {
        StartCoroutine(SignUpCoroutine(username, email, password));
    }
    private IEnumerator SignUpCoroutine(string username, string email, string password)
    {
        yield return new YieldTask(FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task =>
        {
            var dependencyStatus = task.Result;
            if (dependencyStatus == DependencyStatus.Available)
            {
                fAuth = Firebase.Auth.FirebaseAuth.DefaultInstance;
                //FirebaseAnalytics.SetAnalyticsCollectionEnabled(true);
            }
            else
            {
                Debug.LogError(string.Format(
                  "Could not resolve all Firebase dependencies: {0}", dependencyStatus));
            }
        }));
        yield return new YieldTask(fAuth.CreateUserWithEmailAndPasswordAsync(email, password).ContinueWith(task =>
        {
            if (task.IsCanceled)
            {
                Debug.LogError("CreateUserWithEmailAndPasswordAsync was canceled.");
                return;
            }
            if (task.IsFaulted)
            {
                Debug.LogError("CreateUserWithEmailAndPasswordAsync encountered an error: " + task.Exception);
                return;
            }
            signUp = true;
            // Firebase user has been created.
            Firebase.Auth.FirebaseUser newUser = task.Result;
            Debug.LogFormat("Firebase user created successfully: {0} ({1})",
                newUser.DisplayName, newUser.UserId);
        }));
        if(signUp)
        {
            databaseManager.SetUpDatabase(username, email);
            SceneManager.LoadScene("MainMenuScene");
            signUp = false;
        }
    }

The code above used to work but now it gives me the error:

System.Threading.Tasks.Task FirebaseApp.CheckAndFixDependenciesAsync()
Argument 1: cannot convert from System.Threading.Tasks.Task to System.Threading.Tasks.Task

Can anyone help me?

Thank you.

YieldTask.cs looks like this:

using System.Threading.Tasks;
using UnityEngine;

public class YieldTask : CustomYieldInstruction
{
public YieldTask(Task task)
{
Task = task;
}

public override bool keepWaiting => !Task.IsCompleted;

public Task Task { get; }
}
