MongoDB C# driver WithReadPreference vs ConnectionString readprefrence

[siraj....@icloud.com]

I was wondering which setting takes precedence when creating a collection using 

.WithReadPreference(ReadPreference.SecondaryPreferred)

While having a connection string such as :

mongodb://host.example.com/?readPreference=primary

WithReadPreference will take precedence. Order of precedence for all settings is:

1. Operation

2. Collection Settings

3. Database Settings

4. Connection String

In this case, you are creating a new collection with a specific read preference, so it amounts to a collection setting.

Cool ! this makes sense. Is this documented somewhere or  maybe it is based on something you've tested ?. I think this definitely should be documented.
