Out of memory on DataTable. WinForm works fine.

I have a datatable with 182K rows and 167 columns. I built 2 simple projects:

WPF

DataTable dt = GetTable();

dgMain.DataSource = dt.AsEnumerable();

    <Grid>
        <igDP:XamDataGrid Name="dgMain"/>
    </Grid>

WinForm

DataTable dt = GetTable();

dgMain.DataSource = dt.AsEnumerable();

The WinForm loads fine as does the WPF form. However, the WPF gets a stuck clock and ultimately goes to an out of memory exception. The WinForm works as soon as it is loaded. both load about the same time.

I have been doing more testing and that doesn't appear to be it. I sometimes see a stuck clock, other times, i do not. In WInForm, it runs fine every time. I am happy to send the solution or to rty and do some experimentation to find out what is happening.

Constructor:

            var dc = new DataClasses1DataContext();
            var recs = (from p in dc.GetTable<SAS_STATUS>()
                        select p
                        )
            ;
 
            dgMain.DataSource = recs;

This happens if BindToSampleData is set True and the DataSource is set in code behind. Hence, remove the sample data binding and the problem is corrected.
