Probably @lewing team should look first
and not System.Data folks

Weird failure, test is:

        [Fact]
        public void Bug55978()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("StartDate", typeof(DateTime));

            DataRow dr;
            DateTime date = DateTime.Now;

            for (int i = 0; i < 10; i++)
            {
                dr = dt.NewRow();
                dr["StartDate"] = date.AddDays(i);
                dt.Rows.Add(dr);
            }

            DataView dv = dt.DefaultView;
            dv.RowFilter = string.Format(CultureInfo.InvariantCulture,
                                "StartDate >= #{0}# and StartDate <= #{1}#",
                                DateTime.Now.AddDays(2),
                                DateTime.Now.AddDays(4));
            Assert.Equal(10, dt.Rows.Count);
            Assert.Equal(2, dv.Count);
        }

Doesn't seem actionable unless it shows up more frequently.

I'm not sure what Bug55978 was but it does seem like

would be a more stable test 😉

The data is gone and this doesn't seem to be recurring so closing.
