Warning : This is a work in progress !!!

If you want to contribute or test :

• Code is a work in progress, no available Nuget packages at this time.
• Code is a work in progress, I found bugs every days. No doubt you'll find a lot, too. Keep calm and open an issue :)
• Code is a work in progress, if you want to test / code / you need to install Visual Studio 2017 Preview to be able to target .net standard 2.0.

Go download a free version here : Visual Studio 2017 Preview

TL;DR

DotMim.Sync is a straightforward SDK for syncing relational databases.
It's .Net Standard 2.0, available and ready for IOT, Xamarin, .NET, and so on :)

Multi Databases	Cross Plaform	.Net Standard 2.0

It's based on a master slaves architecture :

• One provider, as the master, for the server side.
• One or more provider(s) for the client(s) as slave(s).
• One sync agent object SyncAgent to handle the sync process.

Here are the nuget packages :

• DotMim.Sync.Core : https://www.nuget.org/packages/Dotmim.Sync.Core/ : This package is used by all providers. No need to reference it (it will be added by the providers)
• DotMim.Sync.SqlServer : https://www.nuget.org/packages/Dotmim.Sync.SqlServer/ : This package is the Sql Server package. Use it if you want to synchronize Sql Server databases.
• DotMim.Sync.Sqlite : https://www.nuget.org/packages/Dotmim.Sync.Sqlite/ : This package is the SQLite package. Be careful, SQLite is allowed only as a client provider (no SQLite Sync Server provider right now )
• DotMim.Sync.MySql : https://www.nuget.org/packages/Dotmim.Sync.MySql/ : This package is the MySql package. Use it if you want to synchronize MySql databases.
• DotMim.Sync.Web : https://www.nuget.org/packages/Dotmim.Sync.Web/ : This package allow you to make a sync process using a web server beetween your server and your clients. Use this package with the corresponding Server provider (SQL, MySQL, SQLite).

TL;DR: I Want to test !

If you don't have any databases ready for testing, use this one : AdventureWorks lightweight script for SQL Server

The script is ready to execute in SQL Server. It contains :

• A lightweight AdvenureWorks database, acting as the Server database (called AdventureWorks)
• An empty database, acting as the Client database (called Client)

Here are the simplest steps to be able to make a simple sync :

• Create a .Net Core 2.0 or .Net Fx 4.6 console application.
• Add the nugets packages DotMim.Sync.SqlServer and DotMim.Sync.Sqlite
• Add this code :

// Sql Server provider, the master.
SqlSyncProvider serverProvider = new SqlSyncProvider(@"Data Source=(localdb)\MSSQLLocalDB; Initial Catalog=AdventureWorks;Integrated Security=true;");

// Sqlite Client provider for a Sql Server <=> Sqlite sync
SQLiteSyncProvider clientProvider = new SQLiteSyncProvider("advworks.db");

// Tables to be synced
var tables = new string[] {"ErrorLog", "ProductCategory",
    "ProductDescription", "ProductModel",
    "Product", "ProductModelProductDescription",
    "Address", "Customer", "CustomerAddress",
    "SalesOrderHeader", "SalesOrderDetail" };

// Agent
SyncAgent agent = new SyncAgent(clientProvider, serverProvider, tables);

do
{
    var s = await agent.SynchronizeAsync();
    Console.WriteLine($"Total Changes downloaded : {s.TotalChangesDownloaded}");

} while (Console.ReadKey().Key != ConsoleKey.Escape);
