SGMLReader: assembly does not allow partially trusted callers

[cveld]

Hi SGMLReader development community,

I am trying to put SGMLReader into good use within my shared hosted ASP.NET environment.
Unfortunately SGMLReader runs into an Security Exception: 'That assembly does not allow partially trusted callers'.

Can this be circumvented somehow?

Regards,

Good question. Why doesn't it allow partially trusted callers? I don't have any experience with CAS. So I'd need input on why SGMLReader wouldn't be safe to use. It might boil down to missing attributes or something like that.
