Determines whether security settings are enabled at design time. When this option is cleared, all other options on the Security page are unavailable.
When you publish an application by using the Publish wizard, this option is automatically enabled.
When you select this option, you have the choice of selecting one of two radio buttons: This is a full trust application or This is a partial trust application.
By default, for WPF Web Browser Application projects, this option is selected.
By default, for all other project types, this option is cleared.
This is a full trust application
If you select this option, the application receives Full Trust permissions when it is installed or run on a client computer. Avoid using Full Trust if possible, because your application will be granted unrestricted access to resources such as the file system and the registry.
By default, for WPF Web Browser Application projects, this option is set to Partial Trust.
By default, for all other project types, this option is set to Full Trust.
This is a partial trust application
If you select 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 that are required by your application. For more information about configuring security permissions, see Code Access Security for ClickOnce Applications.
You can specify the Partial Trust security settings by configuring the options in the ClickOnce Security Permissions area.
Specifies a default set of code-access security permissions to use as a starting point when you configure permissions. Choose (Custom) to start with no permissions enabled, or choose Internet or Local Intranet for a restricted permission set.
By default, for WPF Web Browser Application projects, this option is set to Internet. By default, the Internet zone for that project type includes the permissions WebBrowserPermission and MediaPermission, which are not used in other project types.
The Included column contains a green check-mark icon for any permissions that are included. It contains 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. Clicking Include includes the permission, clicking Exclude excludes it, and clicking (Zone Default) includes or excludes it depending on the value selected in the Zone your application will be deployed from list.
Changing permissions for a WPF Web Browser Application will cause it to fail at run time. The application will not run in a modified zone because it cannot gain the elevated privileges required in order to be granted the permissions. For more information, see Code Access Security for ClickOnce Applications.
