Here's a working example of using MongoDB with ASP.NET / C# that demonstrates all the basic operations in MongoDB and encapsulates them in Web API. The example application is a simple Todo list. It's pretty simplistic, but it's more or less the pattern I'm using right now for data access against MongoDB.

Apple's MapKit JS isn't currently as widely used as some alternative web mapping solutions, but it's a reasonable option, depending on your needs.

This seems to be a difficult solution to search for at the moment. The MongoDB .NET driver documentation links to the unit test files on GitHub for examples on aggregation related items, but the links are broken.

Basically what I was trying to do would be relatively easy with SQL -- a SELECT DISTINCT from a table/collection based on multiple fields. I really just wanted to get the unique combinations of several fields at the database layer without having to retrieve all the documents from the collection, and then figuring out which were distinct.
