## Overview

M2M4RIA is an extension for [OpenRIAServices](https://github.com/OpenRIAServices/OpenRiaServices) that adds support for many-2-many relations.

## Features

* Can be installed with NuGet.

* Supports Entity Framework code-first, model first, and DbContext.

* A strongly-typed configuration mechanism using the [Fluent Metadata API](https://riaservicescontrib.codeplex.com/wikipage?title=FluentMetadata%20for%20WCF%20RIA%20Services) for OpenRIAServices

* A code generator that seamlessly integrates with the code generator of OpenRIAServices.

* Requires only a minimal adaption of your data model (see StepByStepInstructions on wiki).

* Supports many-2-many relations with composite keys.

## Download

M2M4RIA is distributed as a collection of NuGet packages:

* [OpenRIAServices.M2M](https://nuget.org/packages/OpenRiaServices.M2M) This is the server-side part of M2M4RIA. It contains an entity code generator and an extension to the fluent metadata configuration for OpenRIAServices.

* [OpenRIAServices.M2M.LinkTable](https://nuget.org/packages/OpenRIAServices.M2M.LinkTable) This is a generic link table implementation that is used for creating "link table" views for your M2M relations (see [GeneralOverview](../GeneralOverview)).

* [OpenRiaServices.M2M.Client](https://nuget.org/packages/OpenRiaServices.M2M.Client) This is the client-side part of M2M4RIA. It contains classes for creating M2M views (see [GeneralOverview](../GeneralOverview)).

## Usage

1. Add the [M2M4RIA NuGet](https://nuget.org/packages?q=OpenRiaServicesM2M) packages to your solution.

2. Create LinkTable entities (By subclassing a generic LinkTable class provided by M2M4RIA).

3. Extend your data model with "link table" views.

4. Configure your M2M relations using the fluent metadata API.

5. Add Insert/Delete operations to your domain service for your link table entities
