Hi Ryan
That library isn't maintained anymore. I had a look and the ClearTables method is just doing a protocol.DeleteRows with the primaryKeys (via GetColumn). The GetColumnsAsDictionary is a regular GetColumns which is looped over and put in a dictionary. You could easily recreate these methods in your precompile QAction and remove the reference to UtilityLibrary (as that will be kept internal).

Hi Ryan
I meant the protocol.DeleteRow. Instead of the 'raw' calls, I'll do you one better. Recently a new NuGet was made that contains some extension methods which are a clearer than the old NotifyProtocol calls.
You need to install the Skyline.DataMiner.Utils.Protocol.Extensions NuGet in your QAction. Then add the using 'using Skyline.DataMiner.Utils.Protocol.Extensions' at the top. Then in your code you can add these methods:

public static void ClearTable(SLProtocol protocol, int tablePid)
{
object[] keys = protocol.GetColumn(tablePid, 0);

protocol.DeleteRows(tablePid, keys);
}

public static IDictionary<string, object> GetColumnAsDictionary<T>(SLProtocol protocol, int tablePid, uint columnIdx)
where T : IConvertible
{
IDictionary<string, object> result = new Dictionary<string, object>();
object[] columns = protocol.GetColumns(tablePid, new uint[] { 0, columnIdx });
object[] keys = (object[])columns[0];
object[] values = (object[])columns[1];

for (int i = 0; i < keys.Length; i++)
{
result.Add(Convert.ToString(keys[i]), values[i].ChangeType<T>());
}

return result;
}

private static T ChangeType<T>(this object obj)
where T : IConvertible
{
if (obj == null)
{
return default(T);
}

var type = typeof(T);

if (type.IsEnum)
{
return (T)Enum.ToObject(type, obj.ChangeType<int>());
}

if (type != typeof(DateTime))
{
return (T)Convert.ChangeType(obj, type);
}

var oadate = Convert.ToDouble(obj);

if (oadate.CompareTo(-657435.0) >= 0 && oadate.CompareTo(2958465.99999999) <= 0)
{
object date = DateTime.FromOADate(oadate);

return (T)date;
}

throw new OverflowException($"{obj} is not a valid OA Date, supported range -657435.0 to 2958465.99999999");
}
