Welcome to the Majorsilence Reporting (formerly My-FyiReporting) wiki.
Majorsilence Reporting is a powerful, open-source .NET reporting framework for creating, designing, and delivering rich reports. Supporting .NET 8.0 and 10.0, it provides a flexible platform for building reports from a variety of data sources. With a drag-and-drop designer, multiple viewer options, and cross-platform rendering via SkiaSharp, it suits both desktop and web applications.
The core engine supports Linux and macOS for server-side report generation. The WinForms designer and viewer are Windows-only.
