Deploying Desktop Applications
Applications developed for desktop are installed like any other Microsoft Windows application. To install Microsoft SQL Server Compact 3.5 (SQL Server Compact 3.5) with the application, you must run the SQL Server Compact 3.5 installer for desktop computers (SSCERuntime-ENU.msi). Installing SQL Server Compact 3.5 by running the installer registers the native DLLs and puts the managed assemblies in the Global Assembly Cache. This makes sure that the installation of the SQL Server Compact 3.5 on the computer can be serviced by Microsoft Update or similar technologies in future.
The installer contains the following libraries:
SQLCEOLEDB35.DLL (OLEDB data provider)
System.Data.SqlServerCe.dll (ADO.NET data provider)
For more information about building a Windows application that uses SQL Server Compact 3.5, see How to: Build and Deploy an Application to a Desktop.
