This example is unavailable in v25.2+ since we ended XAF WebForms & WinForms .NET Framework support in our v25.2+ release cycle. We also removed all XAF .NET Framework and legacy .NET modules/APIs, and older/deprecated Security System implementations from our source code.
For more information, refer to the following article: XAF - Legacy .NET Framework (WinForms and ASP.NET WebForms) APIs, .NET-based API/Modules, and Security System have been removed from distribution
