Enable ClickOnce Security Settings

Determines whether security settings are enabled at design time. When this option is unchecked, all other options on the Security page are unavailable.

Note
When publishing an application by means of the Publish wizard, this option is automatically enabled.

When the check box for this option is checked, you have the choice of selecting one of two option buttons: This is a full trust application or This is a partial trust application.

This is a full trust application

If you check this option, the application receives Full Trust permissions when it is installed or run on a client computer. Full Trust is the default option, but you should avoid using this option if possible, as your application will be granted unrestricted access to resources such as the file system and the registry.

This is a partial trust application

If you check this option, the application receives Partial Trust permissions when it is installed or run on a client computer. Partial Trust means that the code access security permissions for your application include only those permissions required by your application. For more information on configuring security permissions, see Code Access Security for ClickOnce Applications.

You can specify the Partial Trust security settings using the options in the ClickOnce Security Permissions area.

Zone your application will be installed from

Specifies a default set of code-access security permissions to use as a starting point when configuring permissions. Choose (Custom) to start with no permissions enabled, or Internet or Local Intranet for a restricted permission set.

Note
You should always customize the permission set to include only those permissions required by your application. For more information, see How to: Set Custom Permissions for a ClickOnce Application.

Permissions required by the application

Contains a table of code security permissions.

The Included column contains a green check-mark icon for any permissions that are included, or a yellow warning icon if the permission included is not included by default in the specified security zone.

The Permission column contains the names of all permission sets; permission sets that have been modified are displayed in bold text.

The Setting column contains a drop-down list with three choices: choosing Include will include the permission, choosing Exclude will exclude it, and choosing (Zone Default) will include or exclude it based on the value selected in the Zone your application will be deployed from list.

Calculate Permissions

Launches the Permission Calculator tool, which analyzes your application and sets the permissions in the Permissions required by the application table based on the results. For more information, see How to: Determine the Permissions for a ClickOnce Application.

Note
Choosing this option will overwrite any existing permission settings.

Properties

Opens the Permission Settings Dialog Box for the selected permission set in the Permissions required by the application table. The options available in the dialog vary by permission set.

Reset

Resets all permissions in the Permissions required by the application table to the default values for the zone selected in the Zone your application will be installed from list.

Advanced

Opens the Advanced Security Settings Dialog Box, which is used to configure settings for debugging the application with restricted permissions.
