Visual InterDev

The debugger requires that the Microsoft® Internet Information Server (IIS) application to be debugged run out of process. This error indicates that the debugger was unable to change an in-process IIS application to run out of process. As a solution, use the IIS management utility (MMC) to set the application to run out of process before starting the debugger.

Do you want to continue launching the debugger? If you choose Yes, you can view the file in the debugger and in the browser, but will not be able to debug.

For details about server debugging options, see Debugging Server Script. For information about manually enabling debugging on the server, see the topic "Enabling ASP Debugging on the Server" in Troubleshooting.
