Tim:

I am still having issues:

Here are my DataAccessCode:

ABusinessObject

 protected override OakLeaf.MM.Main.Data.mmDataAccessBase CreateDataAccessObject(string dataAccessClassName)
        {
            //return base.CreateDataAccessObject(dataAccessClassName);
            // If WCF mode is set in the config file, return that type
            if (mmAppBase.DefaultDataAccessMode == mmDataAccessMode.Local)
                return base.CreateDataAccessObject(dataAccessClassName);
            else
            {
                //return mmAppBase.Factory.CreateDataAccessObject(dataAccessClassName);
                // Get the Endpoint address
                //string DefaultEndpointNameSetting = System.Configuration.("DefaultEndpointName");
                return mmAppBase.Factory.CreateDataAccessObject(dataAccessClassName);
                //return new mmDataAccessWCFSql(DefaultEndpointNameSetting);
            }

        }

Factory method

  public override OakLeaf.MM.Main.Data.mmDataAccessSql CreateDataAccessSql()
        {
            if (mmAppWPF.DefaultDataAccessMode == OakLeaf.MM.Main.mmDataAccessMode.Local)
            {
                return base.CreateDataAccessSql();
            }
            else
            {
                // Get the Endpoint address
                string DefaultEndpointNameSetting = mmAppWPF.AppSettingsMgr.GetSetting("DefaultEndpointName");

                return new mmDataAccessWCFSql(DefaultEndpointNameSetting);
                
            }

        }

This did not resolve the issue as I am using Entity framework (EF) for my business object. The datasourceclass for EF is DataAccessSqlEF and not DataAccessSQL.

Well I then changed the configuration for EF to use DataAccessSql and not DataAccessSQLEF. That instantiated the data access object but gave an error at run time at the following line on the mmDataAccessWCFSQL:

// Get the data access object
ImmDataAccessEF dao = businessObject.GetDataAccessObject() as ImmDataAccessEF;

Obviously I am missing something simple and critical.
