Welcome to xSQL Schema Compare SDK for SQL Server

xSQL Schema Compare SDK for SQL Server is a library that allows you to quickly and efficiently compare and synchronize SQL Server databases in your .NET applications. You can, for example, compare the database schemas, generate and execute the synchronization script, save the database to a snapshot file or create the database from a snapshot file, compare snapshots and more.

Starting with the version 4.0, Schema Compare SDK, designed from the ground up with the developers in mind, includes many new and improved features:

More than 100 comparison options
New scripting and execution options
It supports all SQL Server versions, starting with SQL Server 2005, including Azure SQL Database
A new exception handling, with extensive logging
An improved cross-version comparison
A new dependency algorithm, which ensures a fast and accurate synchronization script
Many new events that can be used to track the progress of the comparison, cancellations, script execution
An improved scripting component that honors the database version and the compatibility level

Schema Compare SDK is implemented as a set of .NET assemblies. It is a self-contained API with no dependencies on external libraries other than .NET Framework.
