Microsoft Report Viewer !!link!!

Microsoft Report Viewer is a collection of controls and runtime components that allow applications built on the .NET Framework to display reports designed with Microsoft reporting technology. It is a key "piece" for developers and end-users working with RDLC (Report Definition Language Client-side) SQL Server Reporting Services (SSRS) Core Components & Versions

• File Format: Uses RDL (Report Definition Language) files stored on the SSRS server.
• Data Handling: The SSRS server connects directly to the data source, executes queries, and renders the report. The control simply receives the rendered stream.
• Dependencies: Requires a connection to an SSRS instance (SQL Server).
• Use Case: Best for centralized reporting solutions where reports are managed by a dedicated team and require shared schedules, subscriptions, and caching.

• [ ] Identify your target .NET version and choose the correct MSI or NuGet package.
• [ ] Match the RDLC TargetServerVersion to your runtime.
• [ ] For new web projects, abstract the Report Viewer behind an API that returns PDFs.
• [ ] Always set Copy Local to True for deployment.
• [ ] Monitor Microsoft’s GitHub repository (Reporting-Services) for critical updates.

• .NET Framework 4.6.1 – 4.8.x (no native .NET Core / .NET 5+ support initially – but see note below under "Modern alternatives").
• System.Data.SqlClient / System.Data.Common.
• ReportViewer relies on GDI+ (Windows only) – not cross-platform.
