I have a solution that uses CSLA for Business Layer and LINQ to SQL on another. We need to use WCF so that we can host our database on remote servers but it seems that the application cannot read the web.config file in WCF project using ContextManager. We tried using ConnectionManager and somehow it worked. Is there a known issue with ContextManager(Of Sample).GetManager(DBName) not reading the configuration in the WCF Project? Or I need to set something on both app.config(UI) and web.config(WCF)? Thanks.
