Re: Security.Exception

This exception is thrown by the version 2.0 .NET Framework when an assembly
that is not fully trusted calls attempts to call into a strongly named
assembly that is not marked with AllowPartiallyTrustedCallersAttribute. (A
far more obscure exception is thrown in the v. 1.x Framework.) This is
meant to prevent certain kinds of attacks in which fully trusted code might
be tricked into running potentially dangerous operations on behalf of code
with more restricted permissions.

Based on the error output you provided, it seems a little unlikely that the
partially trusted assembly that is causing the problem is actually your web
application. If this were the case, the exception should have been thrown
for the first line of code in which any use of the assembly in which the
type of your myPdfDocument object is declared. However, given that this is
happening on a beta platform, there could very well be a problem in the
exception details output. To rule out this possibility, might you be able
to trap the exception so that its full details (including the call stack
listing) could be captured via its ToString method?
