Castle Windsor / Core 2.5.3 in medium trust

[Phil Whittaker]

I am trying to run Castle in medium trust as a sandbox. I have added the APTC tag and the [assembly: SecurityRules(System.Security.

SecurityRuleSet.Level1)].

I am still getting a security error when constrcuting dynamic proxy

[SecurityException: Request failed.] Castle.Core.Internal.PermissionUtil.IsGranted(IPermission permission) +0
Castle.DynamicProxy.ProxyGenerator..ctor(IProxyBuilder builder) +90 Castle.Windsor.Proxy.DefaultProxyFactory.Init() +114
Castle.Windsor.WindsorContainer..ctor(String name, IKernel kernel, IComponentsInstaller

What can I do to fix this?

Are you setting up your own appdomain or are you just using asp.net in
medium trust?

Hi Hammet,

I'm also having a Medium Trust issue. And just as FYI, I'm using
FluentNHibernate v1.2 (for NH3.1).

I'm setting it up via web.config:


<location allowOverride="true">
<system.web>
<securityPolicy>
<trustLevel name="Full" policyFile="internal" />
<trustLevel name="High"
policyFile="web_hightrust.config" />
<trustLevel name="Medium"
policyFile="web_mediumtrust.config" />
....
</securityPolicy>
<trust level="Medium" originUrl="" />
</system.web>
</location>

I can provide you a copy of my mediumtrust config file. It was
provided to me by my hosting provider.


Thanks,
Josh

I got somewhere.

I downloaded all the source code, and grabbed the latest releases.

FluentNHibernate (1.2)
Castle.Core (3.0)
NHibernate (3.2)

Issue #1
Fluent is built for NH3.1. It comes with it's own copy of
"NHibernate.ByteCode.Castle.dll" but causes medium trust errors.

Issue #2
After hearing some positive feadback, I tried running Fluent with
NH3.2. However, the "NHibernate.ByteCode.Castle.dll" that came with
Fluent was built for NH2.1. Also "NHibernate.ByteCode.Castle" was
built against Castle.Core v 1.1. The medium trust fix that Krysztof
applied from Martijn Boland was applied after 1.1. Swapping the
Castle.Core.dll doesn't work

Anyway, I was able to get something working. I did so by grabbing the
latest version of NHibernate.ByteCode.Castle's source from NH's git
repository. I compiled it against the latest Castle.Core. I had to do
a minor update to NHibernate.ByteCode.Castle since there was a minor
interface update with NH3.2's AbstractProxyFactory.

It seems to be working now, but it's a bit of a hack. I think the
important thing is to use the latest Castle.Core binary for lazy
loading. I tried Linfu, and I was met with all sorts of errors.


Thanks,
Josh
