Características

  • Entity Framework Core Data Source component:
    • Developers can now bind reports directly to Entity Framework Core DbContext models using a dedicated data source component. The new EF Core Data Source is available in the Standalone Report Designer for .NET and the Web Report Designer, with support for design-time data preview, Shared Data Sources, and parameterized queries.
  • What's Improved:
    • The Windows distribution of Report Server for .NET is now bundled with Standalone Report Designer for .NET.
    • The Reporting engine now loads available rendering extensions on demand for faster application startup.
    • The Reporting engine now supports Firebird .NET Client Data Provider out-of-the-box without manual configuration.
    • The HTML5 Report Viewer now uses CSP-compliant templates instead of inline templates.
