Moq with ReturnAsync for GUID is not working

[m-venkat]

Here is the complete test method itself

[Test]
        public void QuerySingleOrDefaultAsyncGuidGenericUsingDbConnectionInterface()
        {
            var connection = new Mock<IDbConnection>();

            var expected = Guid.Parse("6e4655a7-de30-4bf7-ab86-21509d363104"); 

            connection.SetupDapperAsync(c => c.QuerySingleOrDefaultAsync<Guid>(It.IsAny<string>(), null, null, null, null))
                      .ReturnsAsync(expected);

            var actual = connection.Object.QuerySingleOrDefaultAsync<Guid>("").GetAwaiter().GetResult();

            Assert.AreEqual(actual, expected);
        }

If the type is not GUID it works fine, but if it is GUID it fails
