  • Microsoft .NET Compact Framework

Beta Information

This article discusses a Beta release of a Microsoft product. The information in this article is provided as-is and is subject to change without notice.

SYMPTOMS

If you select Save Emulator state when you shut down Microsoft Pocket PC 2002 Emulator before the debugger stops and then you try to deploy the same application again, you may receive the following error message and Visual Studio .NET does not deploy the application to Pocket PC 2002 Emulator:
There were deployment errors. Continue?

CAUSE

This problem occurs because there is a file sharing violation. By default, application files are saved in the My Device\Program Files\ApplicationName folder in Smart Device Emulator. ApplicationName is the same name as your smart device project. When you select Save Emulator state during shut down, Emulator retains the files under My Device\Prgram Files\ApplicationName folder. When you try to deploy the application again immediately after shut down, Visual Studio .NET does not deploy the application because of the filesharing violation.

WORKAROUND

To work around this problem, use one of the following methods:
  • In the Shut Down dialog box, select Turn off Emulator, and then click OK.
  • Use Soft Reset on the Emulator menu.
  • Stop the application, and then Save Emulator State. To stop the application, use one of the following methods:
    • Close the application by using Running Programs screen of the Emulator.
    • On the Debug menu of Visual Studio .NET 2003, click Stop Debugging.

STATUS

This behavior is by design.
