IIS is not lifting with Hydra plugin

Hello,

I have an ISAPI DLL project written in Delphi 7 that need to be integrated with a managed DLL code written in C #.
To achieve interoperability among these modules, I’m trying to use the Hydra.
But I can not find any examples or reference site (or Wiki) Hydra to use this plugin in an ISAPI application.
I saw the Hydra has an option to create plugin to share nonvisual methods between managed and unmanaged modules and I could implement an example of this in a Windows Forms application.
However, when trying to implement the same example in an ISAPI application, IIS is not being able to lift my application when using my plugin Hydra.
Has anyone had a similar situation, who can help me?
Does anybody know if the Hydra is really upward compatible with an ISAPI application written in Delphi 7 and IIS7.

what exactly does that mean? what error do you get?

If I add the references to use the HYDRA plugin in my dll delphi, IIS 7 can not publish, perform my dll, indicating an internal error(505).

Could you tell if the Hydra is upward compatible with an ISAPI application written in Delphi 7 that it’ll be executed by IIS7?

Unfortunately this is not known problem. Can you check what is the actual error behind this error code?
