I use nhibernate in windows application over Net Remoting. Starting with 1.0.1.0 ( last working version was 0.99.1) the folowing error has trow:

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

Looks like a bug, please add it to JIRA.

no it is not.
finally I can help :lol:

Since sp2, Microsoft has raised the security on remoting. Therefor, some things don't work anymore.
Luckily, I found out that you can set a property to relax those security restrains back to the pre-SP2 era.

At your server, You have to set the typefilter to "Full".
This is how I start my server:


I hope this helps!

Thanx for replay, but it not work. I already use this in server.config file:

<serverProviders>
<formatter ref="soap" typeFilterLevel="Full" />
<formatter ref="binary" typeFilterLevel="Full" />
</serverProviders>

Whitout this the communication is not posible. The problem come when I try to send from remote aplication an object that contain <NHibernate.Bag> collection.

Let say the following objects:
class User{
int Id
string Name
string Pass
IList Addresses}

and

Address{
int Id
string Street
string No
User User}

When I get object user from remote server, work ok. But when I send back the same object I'we got the security error

Can help somebody?

i'm very sorry to hear that. I do not understand why it did not help, I had the exact same stacktrace (if I remember correctly).

I can't reproduce this error with a test case, but I found a way to fix.
After I google a lot, a post from Adam Sills
(http://surrealization.com/archive/2003/08/12/5096.aspx)
solve my problems.
You must include this attribute in Assembly.cs
[assembly: System.Security.AllowPartiallyTrustedCallers]

I've got the same probleme with Nullabes objects.
