console app using GeoProcessor managed assembly won't exit

I have a windows console application written in c# that uses a geoprocessor managed assembly.  An example of how to do this is at 
I find that in the Visual Studio 2010, the console app runs to completion and exits.  If I run the console application on a command line on the same machine, the console application will not exit.  I've narrowed it down to calling GP.Execute. If this doesn't get called, then the application exits as expected when run on a command line.  I even put in code to call Process.Kill in order to terminate the process when it's done and this does not work.  I have to kil it using task manager.

Is there something not documented at that I need to do with the GeoProcessor object in order to allow the process to terminate? 

I know it's easier to see the code, so I'm working on putting together a very small console app that demonstrates this behavior so I can post the code for everyone to see.

I took STAThread attribute off the Main method of the console app and it exits cleanly now.

I'm still working on getting a small console app that shows the problem.  However, I was able to find that the console application will exit and not hang if I make one small change to the code.  In my application, I'm using the "DataManagementTools.Project" object in order to project a feature class in sde into a file geodatabase.  If I change the input dataset from a connection to an sde instance to a feature class in a file geodatabase, then the application will exit when it is done.  Unfortunately, this isn't what I need.  But the problem does seem to be that the input dataset to the DataManagementTools.Project object is a connection to an sde instance.  If I leave everything else the same, and only change this from an sde connection to a feature class in a file geodatabase, then the application will exit and not hang.

So it appears that there is something about using an sde connection with the GeoProcessor object or the DataManagementTools.Project object that is preventing the console application from ever exiting.  I have to use task manager to kill it.

Here's more detail on what I found. 

DataManagementTools.Project projectFC = new DataManagementTools.Project();
//this causes the console app to never exit
projectFC.in_dataset = "Database Connections\\Connection to orct.apollo tlgis.sde\\TLGIS.TL_STRUCTURE_TEN";

//this does not cause the console app to never exit
projectFC.in_dataset = @"C:\temp\CreateTL_PUB01_FGDB\CreateTL_PUB01_FGDB\bin\Debug\source.gdb\TL_STRUCTURE_TEN";

So using an input dataset from sde causes the console app to never exit, but using an input_dataset from a file geodatabase does not cause the console app to never exit.  All other lines of code remain the same.

I attached to the console app when it appeared hung with visual studio and broke into it.  Here's the call stack
It appears that GeoProcessor is trying to shut down and is hanging in the attempt.

Taking off STAThread is not the solution, it will seriously impact the application to be thread unstable and impact the performance a lot. The solution to this is to properly execute the GeoProcessing tools. Within this module, assign NULLs and release all objects properly. I had this problem for awhile, and this resolved my issue with running GeoProcessing tools within my Console Application.

public static void RunTool(Geoprocessor geoprocessor, IGPProcess process, ITrackCancel TC)


// Set the overwrite output option to true


geoprocessor.OverwriteOutput = true;

// Execute the tool



geoprocessor.Execute(process, null);


geoprocessor = null;

process = null;




catch (Exception err)
