.net 4.0 printing problem

[eiro]

hi,

When trying to print a report in a .net 4.0 WPF application with the latest weekly build (5.7.2012) an exception is raised:

Fehler beim Versuch der SecurityTransparent-Methode "Stimulsoft.Report.Print.StiWpfPrintProvider.Print(System.Object, Boolean, Int32, Int32, Int32, System.String)", auf den sicherheitskritischen Typ "System.Printing.PrintTicket" zuzugreifen.

Die Assembly "Stimulsoft.Report.Wpf, Version=2012.2.1313.0, Culture=neutral, PublicKeyToken=ebe6666cba19647a" ist mit "AllowPartiallyTrustedCallersAttribute" markiert und verwendet das Sicherheitstransparenzmodell der Stufe 2. Bei Festlegung der Transparenz auf Stufe 2 werden alle Methoden in AllowPartiallyTrustedCallers-Assemblys standardmäßig sicherheitstransparent, was die Ursache der Ausnahme sein kann.

This error does not occur if i use the latest stable build 2012.1 (thats my workaround at the moment)

See the attached sample project (be sure to use the latest weekly build assemblies)

Hello.

Sorry, we need a little more time to prepare an answer for you.

Thank you.

.... if you want to have this exception in czech language I can send it (I don't like localized framework )
.... no ... but we have the same problem so last prerelease build is not usable for printing.

Attempt by security transparent method 'Stimulsoft.Report.Print.StiWpfPrintProvider.Print(System.Object, Boolean, Int32, Int32, Int32, System.String)' to access security critical type 'System.Printing.PrintTicket' failed.

Assembly 'Stimulsoft.Report.Wpf, Version=2012.2.1314.0, Culture=neutral, PublicKeyToken=ebe6666cba19647a' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.

Maybe System PrintTicket object has [SecurityCritical] atribute, but your PrintWithWpf method hasn't the same trusted level....

Hello.

Thank you for information about this issue.
The bug is fixed. The patch will be available in our next prerelease build this week.

Thank you.
