-As PSObject does not work on PowerShell Core

[Szeraax]

Core has different assemblies for scrubbing DBNull. Here is a fix by another person prior to invoking any Invoke-SqlCmd2 will cause the block in Invoke-SqlCmd2 to silently fail.

# This code scrubs DBNulls.  Props to Dave Wyatt and fffnite

    using System;
    using System.Data;
    using System.Management.Automation;

    public class DBNullScrubber
    {
        public static PSObject DataRowToPSObject(DataRow row)
        {
            PSObject psObject = new PSObject();

            if (row != null && (row.RowState & DataRowState.Detached) != DataRowState.Detached)
            {
                foreach (DataColumn column in row.Table.Columns)
                {
                    Object value = null;
                    if (!row.IsNull(column))
                    {
                        value = row[column];
                    }

                    psObject.Properties.Add(new PSNoteProperty(column.ColumnName, value));
                }
            }

            return psObject;
        }

Is this like difference between:
if ($a -eq $null) {#} and if ($null -eq $a ) {#}
