Subsonic 3.0 Medium Trust Issue

I'm having an issue with running Subsonic in medium trust and don't know if i'm querying wrong - if there is some part of subsonic 3.0.3 that doesn't like medium trust can someone tell me? Someone else posted somethin similar a while ago and there was no real reply on whether it did exist or not (the bug). Rob said it had been tested, while someone else said they still had to bug (SubSonic 3.0 - Medium Trust)

i'm using a query that looks like this:

List<Data.Blog> objBlogPosts = ((from blog in db.Blogs
                                            orderby blog.blogID descending 
                                             select blog).Take(10).ToList());

and the error i'm getting is:

System.MethodAccessException: 
System.Runtime.CompilerServices.StrongBox`1..ctor(System.__Canon) --->
System.Security.SecurityException: Request failed.

The action that failed was:
Demand
The type of the first permission that failed was:
System.Security.PermissionSet
The demand was for:
<PermissionSet class="System.Security.PermissionSet"
version="1"
Unrestricted="true"/>

Thanks in advance. Loving the new subsonic and lambda's etc, just having issues deploying to my first shared-host :(

cheers Doug

Solution

  • Subsonic WILL NOT WORK in shared hosting scenarios ( well the ones that have medium trust anyway). The problem is this line...

    Func<IQueryable> fn = efn.Compile();

    Maybe wait for 3.1 or go to 2.0 as subsonic is absolutely not an option at the moment. It was a great idea but it's sad the neck beards don't tell their users about this issue.

    At least they taught me to include

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

    in my web.config for any development for shared hosting sites.
