See Debugging scripts and Web: errors and troubleshooting An error occurred while trying to run the project: you cannot start debugging on the Web server. This project is not configured as a debug version. Debug an ASP. NET Project Check whether the project has a valid Web. config file, whether the Web. config file sets "debug" to "true", and whether the debug predicate is associated with. aspx. For more information, see debug mode in ASP. NET applications. Debug the ATL server project to verify whether the debug predicate is associated with the ISAPI extension.

Each application can have a friendly name that appears in the Internet Information Service Management Unit to differentiate applications. This application name is not used elsewhere. You can delete a directory from the application boundary so that the application cannot be started for the file requests in this directory and Its subdirectories. Deleting a directory from the application boundary does not delete this directory from the website or computer hard disk. Create an application In the Internet Information Service Management Unit, select the directory where the application starts. You can specify the Home Directory of the website as the starting position of the application. Open the directory properties page, and click the "main directory", "virtual directory", or "directory" tab. Click create. In the Application name text box, enter the application name. Note: If the "delete" button appears instead of the "Create" button, it indicates that the application has been created.

To separate the home directory from the application, click "delete. Select the "run in a separate memory space (independent process)" check box to run the application in a process independent of the Web server process. Running an isolated application can protect other applications (including the web server itself) from this application failure or termination response. Set permissions for Applications Set the permission to "NONE" to prevent any programs or scripts from running. Or It is set to "Pure script" so that applications mapped to the script engine can run in this directory without the need to set the "execution" permission. You can also use the "script" permission for directories that contain ASP scripts, Internet Database Connector (IDC) scripts, or other scripts. The "script" permission is more secure than the "execute" permission because it can restrict applications running in this directory. For information on making an application a script engine, see the application ing properties page. Or Set "scripts and executable files" to allow any application to run in this directory, including ing to the script engine and Windows binary files (. DLL and.. Solution: Go to the default website of the Computer Management Service and application Internet Information Service website, find the project directory, right-click the project, enter the properties menu, and set the application Name Creation button for the Directory Application; select scripts and executable files for execution Permissions
