Error thrown in Copystate method Version 3.5

It is trying to serialize PropertyInfo class.  Could you include the code in your class?  That would make it easier to answer…

Created a business object and an error gets thrown when trying to set the datasource of a BindingSource to my object.  The error is thrown in the CopyState method of the CSLA where it tries to serialize the state of the object.

Error is:

Type 'Csla.PropertyInfo`1[[System.Boolean, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' in Assembly 'Csla, Version=3.5.0.0, Culture=neutral, PublicKeyToken=93be5fdc093e4c30' is not marked as serializable.

All my classes are marked as serializable, so I'm not sure what's going on here.

Hmm…  I wonder if this is because you are inheriting from CommandBase?  Is this the intention?  Typically business objects should inherit from BusinessBase(Of CommandFIle).  Am I off the mark totally?

That's a little difficult to do, as the inheritance chain makes the code a bit complicated.  I have some PropertyInfo objects declared as Private, and some as Public (to be able to access the friendly name).  The objects themselves are very simple, following exactly the style used in the PTTracker library.  Example:

<Serializable()> _

Public Class CommandFile

Inherits CommandBase(Of CommandFile)

#Region " Business Methods "

Private Shared IDProperty As PropertyInfo(Of Guid) = RegisterProperty(Of Guid)(GetType(CommandFile), New PropertyInfo(Of Guid)("ID"))

Public Shared ModelNumberProperty As PropertyInfo(Of String) = RegisterProperty(Of String)(GetType(CommandFile), New PropertyInfo(Of String)("MODEL_NUMBER", "Model Number"))

Public Shared SerialNumberProperty As PropertyInfo(Of String) = RegisterProperty(Of String)(GetType(CommandFile), New PropertyInfo(Of String)("SERIAL_NUMBER", "Serial Number"))

Public Shared TransactionsProperty As PropertyInfo(Of Transactions) = RegisterProperty(Of Transactions)(GetType(CommandFile), New PropertyInfo(Of Transactions)("TRANSACTIONS", "Transactions"))

Public ReadOnly Property ID() As Guid
   Get
      Return GetProperty(Of Guid)(IDProperty)
   End Get
End Property

Public Property MODEL_NUMBER() As String
   Get
      Return GetProperty(Of String)(ModelNumberProperty)
   End Get
   Set(ByVal value As String)
      SetProperty(Of String)(ModelNumberProperty, value)
   End Set
End Property

...Code continues....

That's basically it.  I have one more property declared in my base class, along with some MustInherit functions, but nothing out of the ordinary.
