c# - Custom delivery UI extension generates "Invalid Class Name" error -

-

i've done nothing more compile sample ssrs delivery extension , deploy server per instructions. when make call reportservice2010 listextensions web service method, extension shows in list of results. however, when go create subscription in report manager, choose printer delivery sample drop-down list of available delivery extensions, error:

invalid class name

i'm running ssrs 2012 sp2 (11.0.5569.0) on windows server 2012 r2.

edit: found in logs:

it turns out reportmanager (the asp.net ui) does log c:\program files\microsoft sql server\msrsxx.mssqlserver\reporting services\logfiles directory. saw subscription- (i.e. service-)related events in files , assumed if reportmanager did log, files must elsewhere.

yes, feel bit foolish. okay - do information? time brush on code access security again...

have @ this:
