When setting code access security permissions for a ClickOnce application, you need to start with a base set of permissions on the Security page of the Project Designer.

In most cases, you can also choose the Internet zone which contains a limited set of permissions, or the Local Intranet zone which contains a greater set of permissions. If your application requires custom permissions, you can do so by choosing the Custom security zone. For more information about setting custom permissions, see How to: Set Custom Permissions for a ClickOnce Application.

Note

In ClickOnce for .NET Core and .NET 5 or later, this task is unsupported. For more information, see ClickOnce for .NET.
