I have just released a new beta of the Clips .Net Api. I have enhanced User Defined function, Added Multifield support, and DataObject interaction now works as it should. If you choose to download it, I highly recommend taking a look at ProAi.Clips.TestSuite.UserDefinedFunctionTest.cs. This file contains commented test cases on how to utilize the recent additions. Although this is only a maintance release, if you are using user defined function, this is a major advancement. I really appreciate those of you that are helping me test and enhance the Api; I thing it could really become a very valuable tool, but it is not quite there yet (but it is getting there). I really hope this helps. Hang in there, and let me know your problems, I really do listen.
