An update: I've now recompiled the Ibatis.Net dlls using AllowPartiallyTrustedCallers and have come up with a new exception:
[SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.] System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) +0 System.Security.CodeAccessPermission.Demand() +58 System.Reflection.Emit.DynamicMethod.PerformSecurityCheck(Module m, StackCrawlMark& stackMark, Boolean skipVisibility) +191 System.Reflection.Emit.DynamicMethod..ctor(String name, Type returnType, Type[] parameterTypes, Module m, Boolean skipVisibility) +49 IBatisNet.Common.Utilities.Objects.Members.DelegatePropertySetAccessor..ctor (Type targetObjectType, String propName) +700 IBatisNet.Common.Utilities.Objects.Members.SetAccessorFactory.CreateDynamicP ropertySetAccessor(Type targetType, String propertyName) +235 IBatisNet.Common.Utilities.Objects.Members.SetAccessorFactory.CreateSetAcces sor(Type targetType, String name) +453 IBatisNet.DataMapper.Configuration.ResultMapping.ResultProperty.Initialize(C onfigurationScope configScope, Type resultClass) +336 IBatisNet.DataMapper.Configuration.ResultMapping.ResultMap.GetChildNode(Conf igurationScope configScope) +1570 IBatisNet.DataMapper.Configuration.ResultMapping.ResultMap.Initialize(Config urationScope configScope) +194 I've Googled around a bit and it seems the solution to this is making any members that need to be reflected public. This doesn't really seem realistic - does anyone have any ideas?

Now my host has sent out an email saying that they're switching to medium trust in a week. I decided to test this out by setting the trust level to medium in my application, and sure enough, my ibatis calls no longer work. I've tried marking the EntrepreneurialTechnologies.DatabaseHelper class (which calls Ibatis) with the AllowPartiallyTrustedCallers attribute and signing it, but to no avail. I still get the security exception. What I'd like to know is if this is something that just cannot be done, if Ibatis is fundamentally incompatible with medium-trust environments, or if there is a way to configure things so that it will run in medium trust. Does anyone have this working currently? If this is something obvious that I am not getting about how medium trust works, please forgive me. I've never had to deal with this much before. Any and all guidance is appreciated.
