'cAlgo.API.Application' does not contain a definition for 'Run' and no extension method 'Run' - Winform

Hi,

After I update CTrader to 3.6, I got an error on my code that is running a winform.

It says that  'cAlgo.API.Application' does not contain a definition for 'Run' and no extension method 'Run'.

Am I missing something on the update?
