Install-Package Microsoft.EntityFrameworkCore.DynamicLinq -Version 1.0.9



This is a .NET Core / Standard port of the Microsoft assembly for the .Net 4.0 Dynamic language functionality.


With this library it's possible to write Dynamic LINQ queries (string based) on an IQueryable:

var query = db.Customers
    .Where("City == @0 and Orders.Count >= @1", "London", 10)
    .Select("new(CompanyName as Name, Phone)");

How to use

There are several documentation resources:

  • Wiki : an overview from the basic functionality (correctness ~ 80%)
  • API Documentation : a low-level API description website with some code samples
  • DynamicLinqWebDocs (TODO)

Fork details

This fork takes the basic library to a new level. Contains XML Documentation and examples on how to use it. Also adds unit testing to help ensure that it works properly.

Some background: I forked from and added some more functionality there.
My fork is still visible on github [], however I decided to start a new project + nuget to avoid confusion and create the project according to the new VS2017 + .NET Core rules / standards.

However, currently there are multiple nuget packages and projects available:

Project NuGet Author Comment
