Hi,

 

The UploadModule use Asp.Net Async BeginRequest event,

 

And the code run before your Application_BeginRequest,

 

After the resource sent, (either the Response.End() or Application.CompleteRequest() will execute)

 

So your Application_BeginRequest will not call , but Application_EndRequest will call.

 

I suggest you do this way :

 

Application_BeginRequest (..)
{

  context.Items["MyTransaction"]=true;
}

Application_EndRequest(..)
{

  if(true.Equals(context.Items["MyTransaction"]))

  {

      //dispose the objects..

  }
}

 

 

Regards,
Terry
