SecurityException when passing an MBR param remotely

[Marc Lewandowski]

Hi all,

I'm having an issue with passing a client-activated MBR object as a
parameter to a well-known (singleton) class method. The error I'm getting
is:

Experiments.Remoting.Client.Fixture.PushPop :
System.Runtime.Serialization.SerializationException : Because of security
restrictions, the type System.Runtime.Remoting.ObjRef cannot be accessed.
----> System.Security.SecurityException : Request failed.

Judging from the docs, my code apparently doesn't have infrastucture
permissions, but my attempts to assert the appropriate SecurityPermission
resulted in the same error.

Thanks in advance,
-Marc

I had the same exceptions on a call between two machines, one with framework
1.0 and the other with framework 1.1. Upgrading all machines to framework
1.1 solves me the problem.

It sounds like you need to use TypeFilerLevel = "Full". If you use
TypeFilterLevel = "Low", the remoting infrastructure will only serialize the
most basic types automatically for security reasons. This link will explain
the basics:
