Calling CR2008 RPT file from c# .Net 3.5 app

I don't know if this is the correct place to post this but I am having a problem with my developers. I write Custom CR reports (now using CR 2008) off of a SQL Server 2008 db using tables and views.


They are developing a new application in .Net 3.5 c# and can't seem to get the reports created in CR 2008 to call using the report viewer.

Their only answer seems to be to create the reports in VS 2008 creating the data set for the report in c#.

We did this just fine using CR 11 and VB 6 but for some reason they can't seem to get it to work in .Net 3.5

We want to write the reports in CR 2008 as stand alone RPT files getting the data from the database and call them from the new application.

What are they missing?


Thanks
