The most recent stable version is 2.7.0.0 with support for multithreading, parallel for and multiple active results sets with optional extended result sets with rich information about query. Starting with version 2.6 changes can also be tracked.

SQLDatabase.Net is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. It is single threaded and works with existing process. It is developed in .net, mono and xamarin. It is one of the fastest-growing database engines around, it supports both on disk and in-memory database engines with ability to provide external memory stream for further control on your data, same format for Android, iOS and ASP.NET. It's free to use in any kind of project, including commerical use projects.

The engine is not a standalone process however you can link it statically or dynamically as per your requirement. The non PCL library accesses its storage files directly, you simply reference it in your project and copy it along your program for deployment, the portable class library accesses stream and memory stream and allow application to have complete control on file.

It's reliable, fast and free and can be redistributed with your program or can even be merged using ILMerge utility. It was written in .Net 2.0 but with current version 1.0.0.0 require minimum .Net 3.5 Client Profile and Portable Class Library verion require .Net 4.5. Starting version 2.0.0.0 minimum .NET 4.0 Client Profile is required. Database file format is same between all versions, upgrade does not require any changes to data or database file.

Get Started

using SQLDatabase.Net.SQLDatabaseClient;
using (SqlDatabaseConnection cnn = new SqlDatabaseConnection()) 
{
	cnn.ConnectionString = "SchemaName=db;uri=file://C:\\Folder\\dbFile.db";
	cnn.Open();

if (cnn.State == ConnectionState.Open)
	{
		using (SqlDatabaseCommand cmd = new SqlDatabaseCommand())

		{
			cmd.Connection = cnn;
			cmd.CommandText = "SELECT * FROM Table";
			cmd.ExecuteReader();
		}
	}
} 
					

Portable Class Library

Portable class library has minor few limitations, e.g. there is no encryption in verion 1.0.0.0 and requires stream or memory stream provided by the application.

						
using SQLDatabase.Net.PCL.SQLDatabaseClient;

using (SqlDatabaseConnection cnn = new SqlDatabaseConnection()) 
{
	cnn.Stream = new FileStream(FILENAME , FileMode.OpenOrCreate);
	cnn.CloseStreamsOnDispose = true; //optional
	cnn.ConnectionString = "SchemaName=db;uri=file://FILENAME;";
	cnn.Open();

if (cnn.State == ConnectionState.Open)
	{
		using (SqlDatabaseCommand cmd = new SqlDatabaseCommand())
		{
			cmd.Connection = cnn;
			cmd.CommandText = "SELECT * FROM Table";
			cmd.ExecuteReader();
		}
	}
}
