Does anybody knows how to solve the problem? I added [Serializable]
attribute to the following classes in
Microsoft.Practices.EnterpriseLibrary.Data namespace, but I still get
the error. Thanks.
Database.cs
DatabaseFactory.cs
DatabaseProviderFactory.cs
DBCommandWrapper.cs
Server Error in '/' Application.
