From: Ben on 25 Jul 2006 10:00 Hi, I wrote a C# application that is using the Data Access Application Block Enterprise Library, Jan 2006. When i'm running the application on my local machine everything works fine. The problem occur when i'm trying to run the application from a remote computer using shortcut, i get the following error: System.TypeInitializationException: The type initializer for 'Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.EnterpriseLibraryFactory' threw an exception. ---> System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Practices.ObjectBuilder, Version=1.0.51205.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT: 0x80131417) File name: 'Microsoft.Practices.ObjectBuilder, Version=1.0.51205.0, Culture=neutral, PublicKeyToken=null' ---> System.Security.Policy.PolicyException: Required permissions cannot be acquired. at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Boolean checkExecutionPermission) at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Int32& securitySpecialFlags, Boolean checkExecutionPermission) at Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.EnterpriseLibraryFactory..cctor() --- End of inner exception stack trace --- at Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.EnterpriseLibraryFactory.BuildUp[T](String id, IConfigurationSource configurationSource) at Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.NameTypeFactoryBase`1.Create(String name) at Microsoft.Practices.EnterpriseLibrary.Data.DatabaseFactory.CreateDatabase(String name) Any help is welcome. Thanks! Ben

From: Nicholas Paldino [.NET/C# MVP] on 25 Jul 2006 11:54 Ben, When you are running an application from a remote computer, it does not run with full trust. You will have to launch the application from your local computer or go to the .NET Framework Administration tool and configure the framework to grant your assembly the permissions you require.

From: Ben on 26 Jul 2006 03:35 Thank's both of you for the quick respond. I tried to use the .NET Framework Administration tool to configure the framework to grant the assembly the permissions, but i get the following error: Application attempted to perform and operation not allowed by the security policy. To grant this application the required permission, contact your system administrator, or use the Microsoft .NET Framework Configuration tool. Hash for the assembly cannot be generated. I also got this error message when i tried to grant permissions to local assembly, while i'm a system administrator on my local machine. Do you know what i'm missing?
