In the section "Selecting an IdGenerator to use for an Id field or property" there is a code sample that is missing a character. Without it, the code does not compile. Here is the original code:

BsonSerializer.RegisterIdGenerator(
typeof(Guid),
ComGuidGenerator.Instance
);

Here is the corrected code:

BsonSerializer.RegisterIdGenerator(
typeof(Guid),
CombGuidGenerator.Instance
);

Notice on the 3rd line, the "b" in "Comb" is missing: Com[b]GuidGenerator.
