According to the documentation on the createIndexes command : If you create an index with one set of options and then issue createIndexes with the same index fields but different options, MongoDB will not change the options nor rebuild the index. The solution is to drop the index and create it from scratch, but that's costly. Is there a way to create an index when there isn't one, do nothing if there is an index with the same options, and replace the index if the options have changed? This question was originally raised by Phil Barresi here but has since been deleted. I had the same problem,

I have a collection in my database where I log events. Each type of event has a different set of data. I've defined this with the following class: [CollectionName("LogEvent")] public class LogEvent { public LogEvent(string eventType) { EventType = eventType; EventData = new Dictionary<string, object>(); } public string EventType { get; private set; } [BsonExtraElements] public IDictionary<string, object> EventData { get; private set; } } Now - this works pretty good to some extent. As long as the elements of the EventData dictionary are simple types... var event = new LogEvent("JobQueues"){

Does the mongodb .net driver offer support for async/await operations? I can't seem to find any info on this. I'm looking for something like EntityFramework has: ToListAsync(), FindAsync(), CountAsync() Is this supported? 2.0 Driver is released. Check it out: https://github.com/mongodb/mongo-csharp-driver Nuget: https://www.nuget.org/packages/MongoDB.Driver I've made some changes in the official driver to make it async as possible. Basically, I've changed the MongoConnection class to use the NetworkStream async methods (WriteAsync and ReadAsync) and propagated the changes all by the code.

I'm currently applying the [BsonRepresentation(BsonType.String)] attribute to all Guid properties in my domain models to have those properties serialized in string format. Besides being tiresome to do, that doesn't work out sometimes, e.g. with custom Wrapper<T> classes: public class Wrapper<T> { public T Value { get; set; } // Further properties / business logic ... } When T is Guid , the Value property will be stored as binary data of type UuidLegacy (as will any property of type Guid that's not decorated with the above attribute). However, I'd like all Guid s, including Wrapper<Guid>.Value

Considering this class: public class Location { public Coordinates Geo { get; set; } public Location() { Geo = new Coordinates(); } public class Coordinates { public decimal Lat { get; set; } public decimal Long { get; set; } } } I have a geospatial index on the collection set like { Geo: "2d" } . Unfortunately the driver tries to store lat/lon coordinates as strings, instead of numbers and I get an error that says Tue Mar 15 16:29:22 [conn8] insert database.locations exception 13026 geo values have to be numbers: { Lat: "50.0853779", Long: "19.931276700000012" } 1ms . To alleviate this

I have to update all the fields except _id. I want to avoid to manually update the 16 fields... All the new fields are stored inside a BsonDocument Thanks for ideas As @Philipp hinted there is a way way to do this. You can actually use the save function ( http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial#CSharpDriverTutorial-Save%3CTDocument%3Emethod ) which will do what he says for you in the database end. So imagine you have a document of: { _id: {}, d: 1 } And that _id already exists, it will replace the previous document with this one. Neat huh? When I understood you correctly,
