SQL Server Compact 3.5 SP1 is not currently optimized to serve as a database for Web sites. By default, connections from ASP.NET-connected applications are blocked in SQL Server Compact 3.5 SP1. SQL Server Compact 3.5 SP1 is optimized for use as an embedded database within applications. Using SQL Server Compact 3.5 SP1 as a database for Web sites requires support for multiple users and concurrent data changes. This can cause performance problems. Therefore, these scenarios are not supported. Other editions of SQL Server, including SQL Server 2005 Express Edition and later versions, are optimized to serve as a database for Web sites.

SQL Server Compact 3.5 SP1 can be used with ASP.NET in application scenarios where ASP.NET is used to create SQL Server Compact 3.5 SP1 databases for synchronization scenarios. Use the following code to change the default behavior of SQL Server Compact 3.5 SP1 to work within ASP.NET.

AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true)

The following example shows how to initialize a new instance of the SqlCeRemoteDataAccess object.

// Connection String to the SQL Server
//
string rdaOleDbConnectString = "Data Source=MySqlServer;Initial Catalog=AdventureWorks; " +
    "User Id=username;Password = <password>";

// Initialize RDA Object
//
SqlCeRemoteDataAccess rda = null;

try
{
    // Try the Pull Operation
    //
    rda = new SqlCeRemoteDataAccess(
        "http://www.adventure-works.com/sqlmobile/sqlcesa35.dll",
        "MyLogin",
        "<password>",
        "Data Source=MyDatabase.sdf");

    rda.Pull("Employees", "SELECT * FROM DimEmployee", rdaOleDbConnectString,
        RdaTrackOption.TrackingOnWithIndexes, "ErrorTable");

    // or, try one of these overloads:
    //
    // rda.Pull("Employees", "SELECT * FROM DimEmployee", rdaOleDbConnectString,
    //     RdaTrackOption.TrackingOnWithIndexes);
    //
    // rda.Pull("Employees", "SELECT * FROM DimEmployee", rdaOleDbConnectString);
}
catch (SqlCeException)
{
    // Handle errors here
    //
}
finally
{
    // Dispose of the RDA object
    //
    rda.Dispose();
}
