At this time, SubSonic does not run in medium trust.

However, we have not recently reviewed what changes and functionality restrictions might be employed to allow such a scenario. I will take a look and see what the possibilities might be for such.

Could you try the following and let me know how things go?

Open up the source code and locate the AssemblyInfo.cs file Properties directory under the SubSonic project
Replace the following value:

[assembly: PermissionSet(SecurityAction.RequestMinimum, Unrestricted = true)]

with

[assembly: PermissionSet(SecurityAction.RequestMinimum, Unrestricted = false)]
Recompile the SubSonic project, then update the reference in your web project (if necessary) and recompile.

This may help to resolve the issue, or at the very least get beyond this specific problem.

I think we're just going to have to go through these one at a time, unfortunately, and I'm not sure if there will be simple solutions to all of them, but we'll try...

Would it be possible for you to try this again using a debug compile of the SubSonic.dll? I'd like to get a more detail call stack and error location...

Hmm... I expected to see line numbers rather than offsets... Are you sure it's using the debug version of the assembly?

In any event, the next thing we should try is to comment out the entire contents of Utility.WriteTrace() in the event that the current environment produces problems in this area.

I`m pretty sure , that i succesfully run 2.0 classes on medium trust( with generated class of course, not with buildprovider).

It's definitely possible, but with so much change in code base, there may be a number of places where a new issue was introduced... However, if we've gotten as far as you have that's pretty good news, and we'll hopefully get to the bottom of it...

Hope it helps.I think that support for medium trust is very important, especially as most of hosting companies restrict that in their enviroments.

I think that as ORM Subsonic does nothing, that could require full trust. Is the WriteTrace writing to system log?

WriteTrace writes to the current TraceContext, if applicable, for web applications, or to the current debug listeners for other apps. These suggest elevated access requirements, and since they are called across the application, I thought it would be good factor to attempt eliminate first. Let me know if you have any success if this the contents are commented out.

I agree on the trust issues, at least for non build provider models... There are certain places where this is difficult, but if possible we'd love address any we can.

Eric, the web application successfully run after comment out the whole WriteTrace content. Soo far no error encountered. Thank you.

Hey guys, I was just testing this out. I'm in a dev environment where I'm manually defining medium trust in the web.config.

The WriteTrace comment works for me as far as using the Save() function on the generated DAL object, but I'm having a problem with binding a collection to a data grid. The data pulls out fine using "ObjectCollection().Load()" I can step the code and set the DataSource on the grid, but during DataBind() I get: Attempt to access the method failed.

This occurs in AbstractList.cs, line 309 and reads:
HiddenForDataBindingAttribute hiddenAttribute =(HiddenForDataBindingAttribute)property.Attributes[typeof(HiddenForDataBindingAttribute)];

//I'm guessing it has to do with the use of typeof() here.

It's contained in the function: private static PropertyDescriptorCollection GetPropertyDescriptors(Type typeOfObject);

Have you all seen anything like this?

Thanks,

-Nathan

Re: help: cannot run on medium trust

There's a good possibility that you're the first to try direct databinding in a medium trust scenario. As you noticed, the HiddenForDatabinding does a lot of Type kung fu, so it's probably a good candidate for these type of medium trust problems...

Your best bet right now may be to just remove [HiddenForDataBinding(true)] attributes from any of the properties and recompile. If you're not using AutoGenerateColumns, these descriptors really aren't necessary, and if you are, you could always hide them after the fact.

Creating a "veneer" for ActiveRecord is one of our future development tasks, which will address this issue in cleaner, trust-safe method. We'd like to make SubSonic medium trust friendly, so please keep us updated on your results and post any bugs as Work Items on CodePlex...

Gotcha! Thanks! Yeah I already checked some of that out. I'm testing it now. I've pretty much decided that I want to go with a full trust applications due to some of the other components, but I would like figure out a way to make the medium trust scenario work for small applications that can be hosted on shared providers.

Thanks for the quick response!
