Getting "Inheritance security rules violated while overriding member: 'Antlr.Runtime.RecognitionException.GetObjectData..." with NHibernate 4.1.0

Question

I'm getting this error from Nhibernate 4.1.0 in release mode with c# ASP.NET application on .NET 4.5.1:

Inheritance security rules violated while overriding member: 'Antlr.Runtime.RecognitionException.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

Being Antl3 an included dll I can't figure out what is the problem

This stackoverflow post pointed me in the right direction.

I needed to have an Antl3 version which had GetObjectData marked with SecurityCriticalAttribute and that was clearly not the version shipped with NHibernate 4.1.0 sources, so I got Antl3 sources from here and looked at RecognitionException under Antl3.Runtime.net40-client and have seen it was correct:

        [SecurityCritical]
    public override void GetObjectData(SerializationInfo info, StreamingContext context)
    {

So I've bult it, replaced the produced dll in the NHibernate-4.1.0.GA-src\lib\net folder and et voila, now the application runs fine

This is most likely due to the fact that your application demands "more trust". You can change the trust level for your application by adding <trust level="Full" /> in your web.config (inside system.web).

<system.web>
    <trust level="Full" />
<system.web>

More about ASP.NET Trust levels can be found here.
