differences between mongo.linq vs c# linq

Are there any differences between MongoDB.Linq vs C# Linq without Join mechanism? In my application, MongoDB is used as storage unit and Client Side Application has been coded via C# Linq Driver.

So, I want to store MongoDB query results to another collection and I want to let Client Side Application for querying Linq.

If there are big differences between C# and MongoDB Linq drivers, it will be big failure for both server and client side applications.
