WinSCpnet and Integration Services catalog

My code works fine in SSIS. I deploy on server (Integration Services catalogs).
When i run from catalog package where there is calling to assembly, it fails with error message "Exception has been thrown by the target of an invocation".
What should i do? Any help?

Did you install the assembly to GAC?

Yes, i made a separate script task with function Publish.GACInstall(...) before adressing to dll script task.

Can you collect more details about the exception? Full callstack, any inner exception, etc.
