Its pretty easy to do in VS 2010
->Open solution explorer for a solution
->Right click the project you wish to run in partial trust mode
->select properties
->select the security tab
->check "Enable ClickOnce security"
-> select "This is a partial trust application"

and your application will run in partial trust mode from now on...
