Passing C# null to Update.SetWrapped<T> should be valid because T is a POCO and not a BsonValue. A C# null value of T will almost certainly be serialized as a BsonNull.Value (although technically it is up to the serializer for T to decide how to serialize C# null).
To reproduce:
public class C { public ObjectId Id { get; set; } public Point P { get; set; } } public class Point { public int X { get; set; } public int Y { get; set; } }
var doc = new C { P = new Point { X = 1, Y = 2 } }; collection.Insert(doc); var id = doc.Id; Console.WriteLine(doc.ToJson()); var query = Query.EQ("_id", id); var update = Update.SetWrapped<Point>("P", null); collection.Update(query, update); doc = collection.FindOne(); Console.WriteLine(doc.ToJson());
In 1.4 and later this throws a NullReferenceException. In earlier versions it did not throw a NullReferenceException but it also didn't work.
