I have a very basic / stripped connection manager with only one property (SSIS 2012). It works fine in design time (you can open the connection manager editor and change the value), but in runtime it only works in 32bit mode. The runtime-validate-method does work, but if everything validates OK then in 64bit it throws an error when you run the package:
Exception deserializing the package "The package failed to load due to error 0xC0011008 "Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored.". This occurs when CPackage::LoadFromXML fails.
The 2 VS projects are .Net 4 class library projects with the Build Platform on "Any CPU"
I only add references to:
Microsoft.SqlServer.ManagedDTS - C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SqlServer.ManagedDTS\v4.0_11.0.0.0__89845dcd8080cc91\Microsoft.SqlServer.ManagedDTS.dll
Microsoft.SqlServer.Dts.Design - C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SqlServer.Dts.Design\v4.0_11.0.0.0__89845dcd8080cc91\Microsoft.SqlServer.Dts.Design.dll
Compiled DLL's are available in GAC and SQL Server connections folder:
I made the sourcecode available via codeplex:
