FeatureActionEventArgs namespace

[BradleyJanke]

What namespace is FeatureActionEventArgs located in?  I cannot compile because the namespace cannot be found.

I am working with: C:\Program Files\ArcGIS\Mobile10.0\DeveloperKit\Samples\ApplicationFramework\WindowsMobile\PopupMenuExtension.zip. 

I copied the usings from the sample and added ESRI.ArcGIS.Mobile and ESRI.ArcGIS.Mobile.Client.  I tried to Google FeatureActionEventArgs and it returns one result: http://bit.ly/Inh8sH

Side question:

Where are the class docs for this API?

[BradleyJanke]

Found ms-help section of the Mobile SDK.  I am baffled that ESRI is still using ms-help instead of having API Docs on a website like all of their other SDK's.... whatever.

Anyway, the help documents the FeatureActionEventArgs class being at ESRI.ArcGIS.Mobile.Client.FeatureActionEventArgs.  However, ESRI.ArcGIS.Mobile.Client is in the using statements.

Any ideas?  The help docs are dated back to 2008........ Even though I downloaded the ArcGIS Mobile SDK a couple weeks ago.
