Hi all,

I'm creating an Outlook add-in, which will use my business layer to carry out some work.

The problem I'm running into is that the add-in doesn't seem to able to use the assemblies because they are signed (and require full trust). The exact message is "That assembly does not allow partially trusted callers. "

Trusting the assembly also doesn't seem to work.

Any ideas?
Thanks
Andy

Some more info..

My assembly seems to load fine, but its getting a security exection when calling the System.Configuration.ConfigurationManager.GetSection method.

The section however is read by a custom section handler (defined in the same assembly as the one doing the call above). So for some reason, my assembly loads, but the CLR can't create an object from that assembly.. wierd.

There is an attribute called something like AllowPartiallyTrustedCallers, which is important to use when building objects that might be loaded in IE. This may be a requirement for Outlook too.

Well, that worked.

I was very suprised though, because the assembly I marked with the attribute WAS loading and executing code, so I was suprised that calling that method would trigger the message.

Thanks!
