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

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).

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);
