Hi, This has been my first project to use NHibernate and I was having no problems locally until I tried publishing the project to my webspace. When I do so I keep getting the following exception. Can anyone please help me figure out how to resolve this.

Full stack trace of any exception that occurs:
System.TypeInitializationException: The type initializer for 'DAL.NHibernateHelper' threw an exception. ---> System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Reflection.Emit.DynamicMethod.PerformSecurityCheck(Type owner, StackCrawlMark& stackMark, Boolean skipVisibility) at System.Reflection.Emit.DynamicMethod..ctor(String name, Type returnType, Type[] parameterTypes, Type owner, Boolean skipVisibility) at NHibernate.Bytecode.Lightweight.ReflectionOptimizer.CreateDynamicMethod(Type returnType, Type[] argumentTypes) at NHibernate.Bytecode.Lightweight.ReflectionOptimizer.GenerateGetPropertyValuesMethod(IGetter[] getters) at NHibernate.Bytecode.Lightweight.ReflectionOptimizer..ctor(Type mappedType, IGetter[] getters, ISetter[] setters) at NHibernate.Bytecode.Lightweight.BytecodeProviderImpl.GetReflectionOptimizer(Type mappedClass, IGetter[] getters, ISetter[] setters) at NHibernate.Persister.Entity.AbstractEntityPersister..ctor(PersistentClass persistentClass, ICacheConcurrencyStrategy cache, ISessionFactoryImplementor factory) at NHibernate.Persister.Entity.SingleTableEntityPersister..ctor(PersistentClass model, ICacheConcurrencyStrategy cache, ISessionFactoryImplementor factory, IMapping mapping) at NHibernate.Persister.PersisterFactory.CreateClassPersister(PersistentClass model, ICacheConcurrencyStrategy cache, ISessionFactoryImplementor factory, IMapping cfg) at NHibernate.Impl.SessionFactoryImpl..ctor(Configuration cfg, IMapping mapping, Settings settings) at NHibernate.Cfg.Configuration.BuildSessionFactory() at DAL.NHibernateHelper..cctor() in C:\Users\John Cleary\Documents\Visual Studio 2005\Projects\EAR_DAL\EAR_DAL\NHibernateHelper.cs:line 30 The action that failed was: Demand The type of the first permission that failed was: System.Security.Permissions.ReflectionPermission The Zone of the assembly that failed was: MyComputer --- End of inner exception stack trace --- at DAL.NHibernateHelper.GetSession() at DAL.ClientCaseNotes.ClientCaseNotesForm.Load(Int32 id) in C:\Users\John Cleary\Documents\Visual Studio 2005\Projects\EAR_DAL\EAR_DAL\ClientCaseNotes\ClientCaseNotesForm.cs:line 42 at CaseNotes.LoadForm(String id)



Thanks,

Have you tried turning off reflection optimisation? Set hibernate.use_reflection_optimizer to false in your config.

Yeah I figured that out after some serious googling. Was in a bit of a panic there as the application was due the following day. They really should make that more clear in the documation or default it to false so that it will run under medium security.
