  • Sync Framework 2.1 Redistributables
    This download provides the Microsoft Sync Framework 2.1 redistributables that developers can include with applications that use synchronization. The Sync Framework components are provided in three separate redistributable packages so that installation can be tailored to application requirements. The three redistributables are:

    • Synchronization.msi: includes managed and native API for the synchronization runtime, core components, and Web synchronization components. This package is a pre-requisite for the other packages and must be installed first.

    • ProviderServices.msi: includes managed and native API for simple custom providers, the file synchronization provider, the metadata storage service, and also DLLs for the lightweight database that the storage service uses.

    • DatabaseProviders.msi: includes managed API for database synchronization providers.

    Redistributing Sync Framework by packaging the SDK or by installing individual DLLs is not supported. The End User License Agreement (EULA) for the redistributable package covers the terms under which developers may use the redistributable. For full details, please review the EULA included in each redistributable.

    For more information about redistributables, see "Redistributing Sync Framework" in the documentation that installs with the Sync Framework SDK, or click the link: Redistributing Sync Framework
