| Description |
|
Consider either of the following: MongoQueryable<T> mongoQuery = query as MongoQueryable<T>; MongoCursor<T> mongoCursor = query as MongoCursor<T>; Calling ToString on either mongoQuery.GetMongoQuery() or mongoCursor.Query. It will return the where clause of a query. But as far as I can tell, there is no way to access other parts of the query such as sort, limit, skip, projects, etc. So if I had: var query = The query part is {age: {$gt: 21} } but I haven't found a way to access the rest of the query. Am I missing it or is this aspect inaccessible from the outside? |

Michael, We are only targeting the aggregation framework with the LINQ rewrite. As such, you'll have access to all the generated stages of the pipeline as BsonDocuments which will obviously include the skips and limits. I'll be working on documentation shortly to demonstrate how to extract this information. CRaig |

Forgot all these things were public Our springs are 3 weeks long and we are 1 week into Sprint 6, so roughly 5 weeks from now that'll start. |

Craig, I'm seeing a lot of features I've requested making it into Sprint 8. That'll be awesome. Do you have a time frame for sprint 8? |

Thanks Mike. This is definitely planned in the Linq rewrite and, I believe is already there, so this is definitely important. We'll keep this open to track it and so you can verify once we publish an early release of the feature. Thanks, |
