I've worked with Crystal Reports in .net 3.5 before, but since upgrading to .Net 4.0 I'm facing this error:
" Error 5 The type or namespace name 'CrystalDecisions' could not be found (are you missing a using directive or an assembly reference?) C:\Users\aligoglos\Documents\Visual Studio 2010\Projects\WPF\ReportTest\ReportTest\CrystalReport1.cs 14 11 ReportTest "
I installed Crystal Reports for Visual Studio 2010, but my error is still unresolved.
Thanks to all.
