[Mono-dev] Difference on reference search between mono 2.4.2 and mono 2.4.3

[Rafael Teixeira]

AFAIK, CrystalDecisions.CrystalReports.Engine is only added to an
ASP.NET project if you add a Report to it. If you don't use reports
yank it out of the project.

Mono doesn't implement the report engine that MS sublicensed from
Crystal Decisions (now part of SAP) to distribute with Visual Studio.

Trying to use the report engine library in Mono brings even more trouble:
1) It depends in many other libs at least used to have many
dependencies on windows-native DLLs, so it has very little chance of
running on Linux.
2) It may be illegal as I think it is distributed under the same
license as the rest of Visual Studio-provided components that allows
you to deploy it only on Windows.

You may try ReportManager an open-source project that hopes to become
a substitute: http://sourceforge.net/projects/reportman/

Hope it helps,
