MongoDB's official C # drive AsQueryable has been pitfall,
Collection. AsQueryable (). Where () has four overload values:

public static IQueryable<TSource> Where<TSource>(this IQueryable<TSource> source, Expression<Func<TSource, bool>> predicate);public static IQueryable<TSource> Where<TSource>(this IQueryable<TSource> source, Expression<Func<TSource, int, bool>> predicate);public static IEnumerable<TSource> Where<TSource>(this IEnumerable<TSource> source, Func<TSource, bool> predicate);public static IEnumerable<TSource> Where<TSource>(this IEnumerable<TSource> source, Func<TSource, int, bool> predicate);

Because the number and list of queries need to be performed simultaneously on the page, the condition is proposed, and the result type is incorrectly selected as IEnumerable. Func Instead of IQueryable Expression >. The result is filtered and sorted in C. Alas, you will need to see the provider in the future using the extension method.
Statistics show that everyone uses the MongoDB driver

The one officially provided is quite useful.

Encapsulate the Context obtained by a connection and GenericDao for business expansion. Then, separate the encapsulated dll and reuse it later.

I have never heard of the one you mentioned, but for third-party drivers, you can consider using it if you have detailed instructions and technical team support.

How to install mongoDB as a system service

The command used is as follows:
