cannot convert from ‘IEnumerable’ to ‘IEnumerable

[TestMethod]
public async void  Select_getallTask()
{

    //Arrange
    IEnumerable<TaskToDo> list = new List<TaskToDo>();
                


    var mockrepo = new Mock<ITaskToDoRepository>();
      mockrepo.Setup(x => x.GetTasks()).Returns(list);

    //Act

    var data = mockrepo.Object.GetTasks();

    //Assert
    Assert.AreEqual(data, list);
}

this gives me error on

mockrepo.Setup(x => x.GetTasks()).Returns(list);

Error:
Severity    Code    Description Project File    Line    Suppression State
Error   CS1503  Argument 1: cannot convert from
'System.Collections.Generic.IEnumerable<ToDoApp.Models.TaskToDo>' to
'System.Threading.Tasks.Task<System.Collections.Generic.IEnumerable<ToDoApp.Models.TaskToDo>>'  UnitTest_ToDoApp    J:SourceRealAppUnitTest_ToDoAppListTest.cs  97  Active

Repo is
public interface ITaskToDoRepository
{
    Task<IEnumerable<TaskToDo>> GetTasks();
    TaskToDo GetTasksById(Guid Id);      

}

I hope you could understand the problem. Thx

Method 1

You should use ReturnsAsync in your setup like as shown below

var mockrepo = new Mock<ITaskToDoRepository>();
                  mockrepo.Setup(x => x.GetTasks()).ReturnsAsync(list);

as your method GetTasks is type of Task<> return type.
