The Security page of the Project Designer is used to configure code access security settings for applications that are deployed by using ClickOnce deployment. For more information, see Code Access Security for ClickOnce Applications.

To access the Security page, click a project node in Solution Explorer, and then, on the Project menu, click Properties. When the Project Designer appears, click the Security tab.

Security Settings

Enable ClickOnce Security Settings

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

Note

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 requests 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 requests Partial Trust permissions when it is installed or run on a client computer. Partial Trust means that only the actions that are permitted under the requested code access security permissions will run. For more information about how to configure 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.

ClickOnce Security Permissions

Zone your application will be installed from

Specifies a default set of code-access security permissions. Choose Internet or Local Intranet for a restricted permission set, or choose (Custom) to configure a custom permission set. If the application requests more permissions than granted in a zone, a ClickOnce trust prompt appears for the end user to grant the additional permissions. For more information about how to configure security permissions, see Code Access Security for ClickOnce Applications.

By default, for WPF Web Browser Application projects, this option is set to Internet.

Edit Permissions XML

Opens the application manifest template (app.manifest) to configure the permissions for the (Custom) permission set.

Advanced

Opens the Advanced Security Settings Dialog Box, which is used to configure settings for debugging the application with restricted permissions. These settings are checked during debugging, and permission exceptions indicate that your application may need more permissions than defined in a zone.
