Remoting exception when upgrading from .Net 1.0 to .Net 1.1

[Mads]

Hi,

we are trying to upgrade our application from .net 1.0
to .net 1.1 framework.

We get the following exception:
System.Security.SecurityException: Type
System.DelegateSerializationHolder and the types derived
from it (such as System.DelegateSerializationHolder) are
not permitted to be deserialized at this security level

We have read a number of posts (including
http://www.ingorammer.com/remotingFAQ/changes2003.html)
and tried to set the typeFilterLevel to "Full" as
suggested.

It did not change the problem, we still get the same
exception.

We have looked at some Remoting samples. The difference
to our application is that we start the remoting with
this function call:

RemotingConfiguration.Configure(remoteConfigFile);

We have a sample project that exposes the problem - can
we upload that to you?

Now we tried to follow the ingorammer directions, but set
the typeLevelFilter programmatically instead of
using .config files. And now it works.

So it seems that settings in the server config file has
no effect?

We only set the typeLevelFilter for the server exe.
