Why is my mocked EF DbSet returning an empty IQueryable?

I'm trying to mock an EF DbSet using Moq so that it behaves as an IQueryable, but I'm getting an empty result when I query it. Here is the code I'm using:

CSHARPCopied
IQueryable<AccessPoint> testAcP =
    new List<AccessPoint>() { new AccessPoint() { Id = 1, Token = "testPoint", Enabled = 1 } }.AsQueryable();
var mockSet = new Mock<DbSet<AccessPoint>>();

mockSet.As<IQueryable<AccessPoint>>().Setup(m => m.Provider).Returns(testAcP.Provider);
mockSet.As<IQueryable<AccessPoint>>().Setup(m => m.Expression).Returns(testAcP.Expression);
mockSet.As<IQueryable<AccessPoint>>().Setup(m => m.ElementType).Returns(testAcP.ElementType);
mockSet.As<IQueryable<AccessPoint>>().Setup(m => m.GetEnumerator()).Returns(testAcP.GetEnumerator());

var dbContext = new Mock<IApplicationDbContext>();

dbContext.Setup(c => c.AccessPoints).Returns(mockSet.Object);
var filter = new AccessPointsFilter() { Enabled = AcPassState.Active };

var areaService = new AccessPointsService(new QuerySelector<AccessPoint>(), new QueryOrderer<AccessPoint>(), dbContext.Object);

var result = dbContext.Object.AccessPoints.AsQueryable();

The expected behavior is that the DbSet returns the test data as IQueryable, but instead, the query yields an empty result. What am I doing wrong and how can I fix this issue?
