Hi,
I don´t understandexactly the question.
Are you developing a GAX recipe that use sharepoint API ?
Could you execute the code from WinForm correctly ?
I had developed some webpart with the Sharepoint extension, and I don´tcompletely sure, but I think that you cann´t use the sharepoint API outside of sharepoint enviroment.
I think that the sharepoint API requires torun in the same AppPool where the sharepoint site is running.
The sharepoint extension (and sharepoit API) was developed to make easy the develop, for example, webpart.
I think that you cann´t use the sharepoint API from Winform or Guidance recipe.
in this post, you can see the problem with the AppPool:

SharePoint and Web ServicesYou can use it without security problems.
