<div dir="ltr">Ok, so I think I misunderstood what a LinkDemand was, as well as the fact that the exception I'm getting is expected behavior.<br><br>I added the [assembly: AllowPartiallyTrustedCallers] attribute to my assembly and now things work fine outside of the debug environment. From what I (now) understand, using the LinkDemand attribute is so that the partially trusted assembly (i.e. the scripts) <b>can't</b> access that method. Does that sound right to you guru types? To test this I imported System.Windows.Forms and tried to call the MessageBox.Show() method which failed while running in the domain, as expected. When I removed the LinkDemand from the ScriptableItem class the calls to it in the script also worked fine.<br>
<br>So all I have to do is decorate the classes I don't want to be imported from my assembly into the script with LinkDemands, I think? Is there some way to reverse that, I.E. some way that I can decorate the classes I want to be accessible rather than the other way around? I suppose another alternative is to create the ScriptableItem wrappers in their own assembly and just reference that, as well as make it callable by partially trusted callers, while leaving my own assembly alone and thus off-limits to an import.<br>
<br>I will play with it some more, I think. I'm sorry to have wasted some of your time. =\<br><br>---<br>LC<br><br><div class="gmail_quote">On Tue, Sep 2, 2008 at 7:38 PM, Leo Carbajal <span dir="ltr"><<a href="mailto:desleo@gmail.com">desleo@gmail.com</a>></span> wrote:<br>

<div dir="ltr">So here's a strange wrinkle,<br><br>when I run this with the debugger (unmodified except for adding the IronPython assemblies as full-trust on the domain) it works fine and as expected. If I run it without the debugger attached it gives me the same exception as before, when I catch the exception myself I also get this tidbit:<br>
<br>The assembly or AppDomain that failed was:<br>Microsoft.Scripting, Version=1.0.0.4000, Culture=neutral, PublicKeyToken=31bf3856ad364e35<br>The Zone of the assembly that failed was:<br>MyComputer<br>The Url of the assembly that failed was:<br>
file:///B:/Code/IronPythonShell/IronPythonShell/bin/Debug/Microsoft.Scripting.DLL<br><br>If I build and compile the code as Release instead of Debug I get: <br><br>System.Runtime.Serialization.SerializationException: Type 'System.Scripting.SourceUnit' in assembly 'Microsoft.Scripting.Core, Version=1.0.0.4000, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable.
<div><br> at Microsoft.Scripting.Hosting.ScriptRuntime.ExecuteFile(String path)<br></div> at IronPythonShell.Program.Main(String[] args) in B:\Code\IronPythonShell\IronPythonShell\Program.cs:line 54<br>
<br>It's a little beyond odd to me, but like I said before I fear I don't fully understand what's going on behind the goo. The only consolation is that I can at least built out my scripting system in working form and later run it under a more trusted domain for production by simply removing the domain from the Runtime.Create() constructor and then adding it later. (At least, I hope this is the case)<br>
