Hi,

i have some problems saving objects to binary file using serialization. Maybe i will just give some source code from my project and then try to explain the problem.
Code:
   [Serializable()]
	public class ObjectRefId : ISerializable
	{
       public ObjectRefId(SerializationInfo objSerializationInfo, StreamingContext objStreamingContext)
      {
         //Retrieve the data of the fields from the SerializationInfo class and
         //set the values into the respective fields.
      }

      [SecurityPermissionAttribute(SecurityAction.Demand, SerializationFormatter = true)]
      public void GetObjectData(SerializationInfo objSerializationInfo, StreamingContext objStreamingContext)
      {
         //Add the fields to be saved into the SerializationInfo class.
         //Provide a name for each field being saved.
      }
	}

      public int LoadFromStorage()
      {
         String sName = "My3rdPartyStream";
         try
         {
            object obj = document.IGet3rdPartyStorage(sName, false);
            if (obj != null)
            {
               UCOMIStream ucomiStr = (UCOMIStream)obj;
               ComStream comStream = new ComStream(ref ucomiStr);
               comStream.Seek(0, SeekOrigin.Begin);

               BinaryFormatter formatter = new BinaryFormatter();
               comStream.Seek(0, SeekOrigin.Begin);
               objRefId = (ObjectRefId)formatter.Deserialize(comStream);
               comStream.Close();
            }
         }
         catch(Exception ex)
         {
            iSwApp.SendMsgToUser2(ex.Message, (int)swMessageBoxIcon_e.swMbWarning, (int)swMessageBoxBtn_e.swMbOk);
         }

         document.IRelease3rdPartyStorage(sName);

         return 0;
      }

      public int SaveToStorage()
      {
         String sName = "My3rdPartyStream";
         try
         {
            object obj = document.IGet3rdPartyStorage(sName, true);
            if (obj != null)
            {
               UCOMIStream ucomiStr = (UCOMIStream)obj;
               ComStream comStream = new ComStream(ref ucomiStr);
               BinaryFormatter formatter = new BinaryFormatter();
               formatter.Serialize(comStream, objRefId);
               comStream.Close();
            }
         }
         catch(Exception ex)
         {
            iSwApp.SendMsgToUser2(ex.Message, (int)swMessageBoxIcon_e.swMbWarning, (int)swMessageBoxBtn_e.swMbOk);
         }

         document.IRelease3rdPartyStorage(sName);

         return 0;
      }
	}
I am developing addin application and i get notifications from host application when it saves and loads its file. I can use this notification to save my own objects within the host application files. If i try to save one of the base objects (like Hashtable) that implements ISeriazible interface, then everything works just fine. If i try to use my own objects that also implements ISeriazible interface, then i get an exception on Deserialize (BinaryFormatter) method. The message text is smth like:
"Cannot find the assembly MyAssemblyTest, Version.. "
At first i thougt that this could happen because my assembly is not "strog named", but i dont really understand how to make it "strong named" assembly..
Any help would be appreciated
