GPToolCommandHelper NOT IN ESRI.ArcGIS.Geoprocessing and GeoprocessingUI deprecated

[JonHall]

I've gone around in circles an hour now migrating 9.3 code to 10.0, due to inability to find the library containing this calls and interface

there are conflicting statements in ESRI's help regarding this Class, and where it went.

It was in GeoprocessingUI

This page implies it's still there:
  ms-help://ESRI.EDNv10.0/esriGeoProcessingUI/html/GPToolCommandHelper.htm
  ArcGIS Developer Help (ESRI.ArcGIS.GeoprocessingUI) 
  GPToolCommandHelperClass Class

This page says "ArcObjects Library Reference (GeoprocessingUI)"
http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#//002p0000000r000000

The IGPToolCommandHelper Interface page says "ArcObjects Library Reference (Geoprocessing)"

Where is it?

Is there a dependent Library of ESRI.ArcGIS.Geoprocessing that I need to add a reference to in order to get to it?

Thanks,
JHall

I've solved the problem.

�??Type Changes between ArcGIS 9.3 and ArcGIS 10.0�?� shows that this interface MOVED from GeoprocessingUI to Geoprocessing, but it has NOT moved.

I finally found the GeoprocessingUI reference, which was hidden by filters. 

After changing the "Add ArcGIS Reference" filters to "Filter by Product" and selecting "ALL", I finally located the GeoprocessingUI - it was not deprecated.

After adding the GeoprocessingUI reference, the IGPToolCommandHelper works.
