        ### Library Powered By

This library is powered by [Entity Framework Extensions](https://entityframework-extensions.net/?z=github&y=system.linq.dynamic.core)

# System.Linq.Dynamic.Core

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

## Overview

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

``` c#

var query = db.Customers

    .Where("City == @0 and Orders.Count >= @1", "London", 10)

    .OrderBy("CompanyName")

    .Select("new(CompanyName as Name, Phone)");

```

Interpolated strings are supported on .NET 4.6(and above), .NET Core 2.1(and above), .NET Standard 1.3(and above) and UAP 10.0(and above).

For example:

``` csharp

string cityName = "London";

int c = 10;

db.Customers.WhereInterpolated($"City == {cityName} and Orders.Count >= {c}");

```

## :exclamation: Breaking changes

### v1.3.0

A breaking change is introduced in version 1.3.0 which is related to calling methods on classes.

Due to security reasons, it's now only allowed to call methods on the standard predefined classes like (`bool`, `int`, `string` ...).

If you want to call a method on an own custom class, annotate that class with the [DynamicLinqType](https://dynamic-linq.net/advanced-extending#dynamiclinqtype-attribute).

Example:

``` c#

[DynamicLinqType]

public class MyCustomClass

{

    public int GetAge(int x) => x;

}

```

If it's not possible to add that attribute, you need to implement a custom [CustomTypeProvider](https://dynamic-linq.net/advanced-configuration#customtypeprovider) and set this to the `ParsingConfig` and provide that config to the dynamic call.

### 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 https://github.com/NArnott/System.Linq.Dynamic and added some more functionality there.
My fork is still visible on github [https://github.com/StefH/System.Linq.Dynamic], 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 |
