-Both COM and URI-launched action providers must have package identity. Package identity is declare in the app package manifest file using the [Identity](/uwp/schemas/appxpackage/uapmanifestschema/element-identity) element. For more information, see [An overview of Package Identity in Windows apps](/windows/apps/desktop/modernize/package-identity-overview).

-URI-launched action providers must also have a trust level of *mediumIL*. If a URI-launched action provider will return outputs, the app must implement the ability to be launched for results. For more information, see [Launch an app for results](/windows/uwp/launch-resume/how-to-launch-an-app-for-results). URI-launched action providers that return outputs must also instantiate the runtime.
