Hi,

I'm also experiencing this issue.  It seems as though it affects
accessing any object byRef over the remoting channel.  Unfortunately, we
don't own the server side of our .NET Remoting and I'm not sure how our
vendor is going to feel about applying the config based fix on their
end.

I upgraded to NUnit 2.6.3 and still experience the issue.

System.Runtime.Serialization.SerializationException - Details Follow:

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

The action that failed was:

Title:
  Security Exception After Upgrading to 2.6.2

Status in NUnit V2 Test Framework:
  Fix Released

Bug description:
  From the mailing list, reported by Andy Sipe:

  We recently upgraded to 2.6.2 from 2.6.1 and now a few of our top
  level integration tests are experiencing remoting security exceptions.

  In particular we are having this exception thrown when attempting a
  request:

  System.Runtime.Serialization.SerializationException : Because of
  security restrictions, the type System.Runtime.Remoting.ObjRef cannot
  be accessed.

  2.6.1 no problem, 2.6.2 this exception -- no other chnages in the
  source.

  Note that this is occurring in our tests not in the nunit framework
  directly.

  I've included a full stack trace at the end of this message.  I'm not
  sure its going to help a whole lot as it occurs in our test code not
  in the nunit code.  Note that in every case the exception is raised
  when the response is deserialized and that the actual request works as
  expected (server gets hit and executes).   To me it looks like there
  is some new security restriction being applied at a somewhat high
  level that is overriding the defaults.

  I was able to work around the issue by setting the type filter and
  some other security settings in the code that configures the security
  surrounding remoting.   Fortunately we handle all of this outside of
  configuration files or I'm unsure it would have worked as changing
  configuration files seemed to have no impact.    Once I set the type
  filter to full everything worked as expected again.

  For our purposes this will likely work as we don't use remoting
  extensively.   That said there is like some change in 2.6.2 that may
  cause others problems as well.

  Thanks -andy
