Description

Implementing IDao and defining Dao method with "ref" parameter
and loading through DaoManager causes
"An unhandled exception of type 'System.ExecutionEngineException' occurred in mscorlib.dll".
This problem only happens if I load my Dao through
DaoManager(of DataAccess Framework) with "ref" parameter and not happens
if I load my Dao directly through SqlMapper(of DataMapper Framework)
with "ref" parameter.
This might be the DynamicProxy issue.

The following snippet describes the differences between the above.
/*************************************************************************************/
private DaoManager daoManager;
private IDailyDao dailyDao = null;
internal DailyService()

{ //DataAccessConfigurator configures and loads DaoManager daoManager = DataAccessConfigurator.GetDaoManager(); }

public bool LoadThroughDaoManager(ref object dailyDB, string sOfficeCode)
{
//This load DailyDao instance through dao.config
dailyDao = daoManager[typeof(IDailyDao)] as IDailyDao;

try
{
//Begin trans
using (IDalSession session = this.daoManager.OpenConnection())

{ dailyDao.SelectDaily(sOfficeCode, ref dailyDB); }
return true;
}
catch (Exception ex)
{
throw new RdbAccessException(string.Format(@"Failed to load Daily throught DailyService.
OfficeCode={0} DailyNo={1}",sOfficeCode,((DailyDB)dailyDB).sNo), ex);
}
}

public bool LoadThroughSqlMapper(ref object dailyDB, string sOfficeCode)
{
IBatisNet.DataMapper.SqlMapper mapper = IBatisNet.DataMapper.Mapper.Instance();

//Directly instantiate DailyDao
dailyDao = new DailyDao();
((DailyDao)dailyDao).SetContext(mapper);

try
{
//Begin trans
using (IDalSession session = mapper.OpenConnection())
{ dailyDao.SelectDaily(sOfficeCode, ref dailyDB); }

return true;
}
catch (Exception ex)
{
throw new RdbAccessException(string.Format(@"Failed to load Daily throught DailyService.
OfficeCode=

{0}

DailyNo=

{1}

",sOfficeCode,((DailyDB)dailyDB).sNo), ex);
}
}

The same exception occurs in the environment of the recent SVN version.
Any response is appreciated.

[Note]
Using NAnt with iBATIS.build file of the recent SVN causes compile error
unless you remove the following files.
IBatisNet.Common.Logging.IDataReaderProxy.cs
IBatisNet.Common.Logging.IDbCommandProxy.cs
IBatisNet.Common.Logging.IDbConnectionProxy.cs
