Marten

The HotChocolate.Data package generally works with any LINQ provider that provides an IQueryable<T>. However, Marten requires special handling. Pagination and projections work out of the box, but filtering and sorting need LINQ expressions translated into a format that the Marten LINQ provider can process. This integration provides custom configurations for that purpose.

You can find a sample project in Hot Chocolate Examples.
