I am very impressed with RS at the moment. I looked briefly at this stuff a year ago when it was to be part of Yukon and liked what I saw a lot. Now the Report interface is done via Visual Studio and it is very powerful. My days of trudging through Crystal Reports or creating ad-hoc aspx pages may be over. The feature I really like are:
- Ability to use DataSets as data sources (as well as standard ODBC, OLEDB, and ADO.NET Managed Providers).
- The ability to render to different formats (including HTML, PDF, image, Excel, etc.)
- A rich sub-report system for indepth reporting.
- Intuitive UI
While I am just toe deep into the RS pool, I will undoubtedly find wrinkles I don't like. But at first glance I am very impressed.
