我是C＃和.Net的新手，并且我有一个C＃应用程序，该应用程序使用开放数据从mysql数据库中显示有关市议会的信息。问题是我尝试按照要求我创建一个接口并设法通过测试的教程使用XUnit和模拟创建单元测试，但是当我尝试运行该应用程序时，它给我以下信息：“发生了未处理的异常在处理请求时。” InvalidOperationException：属性'CMemberId'不是实体类型'Councillors'的导航属性。 “ include（string）”方法只能与“。”一起使用。导航属性名称的分隔列表。
我试图运行该应用程序，它给我以下信息：“处理请求时发生未处理的异常”。 InvalidOperationException：属性'CMemberId'不是实体类型'Councillors'的导航属性。 “ include（string）”方法只能与“。”一起使用。导航属性名称的单独列表。我曾尝试查看导航属性，但无法理解我的问题。

councillorsRepoMock = new Mock<ICouncillorsRepository>();
controller = new CouncillorsController(councillorsRepoMock.Object);
}

public async Task IndexTest_ReturnsViewWithCouncillorsList()
{
// Arrange
var mockCouncillorsList = new List<Councillors>
{
new Councillors { CMemberFname = "mock Councillor 1" },
new Councillors { CMemberFname = "mock Councillor 2" }
};
councillorsRepoMock.Setup(repo => repo.GetAll()).Returns(Task.FromResult(mockCouncillorsList));
// Act
var result = await controller.Index();
// Assert
var viewResult = Assert.IsType<ViewResult>(result);
var model = Assert.IsAssignableFrom<IEnumerable<Councillors>>(viewResult.ViewData.Model);
Assert.Equal(2, model.Count());
}

`````
the application is supposed to display information from the database(sample6Context) but after after creating the interface and the repo, i had to modify the controller to use the interface for mocking and i get the "An unhandled exception occurred while processing the request" error which further indicated "InvalidOperationException: The property 'CMemberId' is not a navigation property of entity type 'Councillors'. The 'Include(string)' method can only be used with a '.' separated list of navigation property names" and points to the "Controllers.CouncillorsController.Index() in CouncillorsController.cs
return View(await _councillorsRepository.GetAll());
can someone please help me out here
