1. What would you like to communicate to the user about this feature? 2. Would you like the user to see examples of the syntax and/or executable code and its output? 3. Which versions of the driver/connector does this apply to?

With the latest version of the mongo db c# driver and linq3, the expression comparison of a string value with the call of a ToUpper is broken.

I want create a dynamic query and create a query expression like this

item => ((item.StringValue != null) AndAlso item.StringValue.ToUpper().Contains("foo"))

which then translate into this

database.collection.Aggregate([{ "$match" : { "$and" : [{ "stringValue" :

{ "$ne" : null }

}, { "_id" :

{ "$type" : -1 }

}] } }])
