Hello, I have converted a .Net 1.1 application to .Net 2.0 using references that are not converted (still 1.1). Now I have problems with crystal decisions reports. First they work fine. But now, calling these reports from a .Net 2.0 application via a .Net 1.1 application it fails showing the dataset. Is someone familiar with this problem? Extra information: Application uses .Net 2.0 Reference (.dll) build in .Net 1.1 uses .Net 2.0 Crystal decisions uses version 9.1.5000.0
