I have a ListItem with TaxonomyField which have some value in it (some term of course). This TaxonomyField is single value only. So now I want to set it to empty, just as it was from the beginning but I can't find the way to do it. What I've tried so far:
It doesn't throw any exception on ClientContext.Update(), but field value for listItems stays unchanged.
taxField.SetFieldValueByValue(listItem, new TaxonomyFieldValue());
This gives me "The method or operation is not implemented." Exception
This also runs without exceptions, but value stays the same. BTW do use such approach, use ParseAndSetFieldValue instead.
So could any one suggest something that would done a trick? Thanks in advance!
