Allow anonymous access to SharePoint application pages

We can access the Application page in SharePoint anonymous site.

·         By default, the page is inherited from LayoutsPageBase. Change the inheritance from “LayoutsPageBase” to “UnsecuredLayoutsPageBase”.

·         Next, we need to override a property of the UnsecuredLayoutsPageBase, to allow the anonymous access. Be sure to change the ‘getter’ to return true

protected override bool AllowAnonymousAccess { get { return true; } }

Example :
