SYMPTOMS
You develop a smart device application on a computer that has Microsoft Visual Studio 2008 and Microsoft Visual Studio 2005 installed. If you deploy the smart device application to an emulator or to a mobile device, the application cannot be started on the emulator or on the mobile device. This problem occurs if the application is based on the Microsoft .NET Compact Framework 3.5 and on the SQL Client for mobile devices (System.Data.SqlClient.dll).

This problem does not occur if the application is based on the Microsoft .NET Compact Framework 2.0 and on the SQL Client for mobile devices.



CAUSE
This problem occurs because the SQL Client for mobile devices is not deployed to the emulator or to the mobile device.



WORKAROUND
To work around this problem, manually deploy the SQL Client to the emulator or to the mobile device. To manually deploy the SQL Client, use the following .cab files:
 * Sql.dev. . . . .cab
 * Sql. . . .cab

Note Each placeholder in the file names represents one of the following values.

You can find these .cab files in the following folder:

%Program Files%\Microsoft SQL Server Compact Edition\v3.5\Devices\Client\ \

Note The .cab files and .dll files in the following folder are also used to install the SQL Client for mobile devices on Windows CE 6.0 devices and to install the SQL Client for Windows Mobile 6.0 devices:

%Program Files%\Microsoft SQL Server Compact Edition\v3.5\Devices\wce500

To deploy the System.Data.SqlClient.dll file by using Visual Studio 2008, copy the files and folder for the SQL Client for mobile devices as follows.



Steps to reproduce the problem

 * 1) On a computer that has Visual Studio 2005 installed, install Visual Studio 2008. During the installation, make sure that the Smart Device Programmability option under Visual C# or under Visual Basic is selected.
 * 2) Create a .NET Compact Framework 3.5-based smart device application.
 * 3) Add a reference for the SQL Client for mobile devices (System.Data.SqlClient.dll).
 * 4) Build the application, and then deploy the application to an emulator or to a mobile device.

Notice that the application cannot be started on the emulator or on the mobile device.
