Question: I am looking out for a good open source Reporting tool/framework for windows based application (WPF). 

The database I am using is sql server 2005.

The typical reports format which I am interested is for e.g. Trial balance, balance sheet, etc (typical banking / finance reporting application).

There should be good support for charting as well.

If anyone has any experience with reporting for WPF application, your inputs will be highly appreciated.

Answer: 
Take a look at <http://wpfreports.codeplex.com/>
[PdfReport](http://pdfreport.codeplex.com/) is a code first reporting engine, which is built on top of the iTextSharp and EPPlus libraries. It's compatible with both .NET 3.5+ Web and Windows applications.
