I am in charge of a project migration from ASP to ASP.Net. We are doing it page by page so here comes to the session sharing. I can share simple data types such as string, int etc. There are a few sessions storing arrays and COM objects. My question is that how do I share these arrays and COM objects between ASP and ASP.Net.

Thanks

You have to have a translation layer in both the ASP and ASP.Net that will put them in a common format in a common place. 

Since they (ASP and ASP.net) don't share a memory space, you can't share them directly.
