is it possible to get somewhere documentation for Fanuc OLP specific .NET API? We have only general Tecnomatix.NET SDK help, but it is useless in case of Fanuc robot associated locations manipulation (especially for UTOOL and UFRAME stuff).
Sorry, but TxEuFanucRjLib.dll or FanucRjxxx.dll are not official API. They are not documented. You can use them, but at your own risk, without support or warranty that the methods or properties inside will keep compatibility.
