c# - Execute some methods from existing WPF Application -

there wpf based application. need implement windows shell sendto functionality it. sendto should execute operation existing application, available in app, files got sendto result.

my idea write second app, intended executed sendto result , add main app reference it, able execute needed part of code sendto command.

is idea? or rather should avoid approach this? main app not simple, uses wpf stuff , services/automapper access database - of course, action execute sendto needs have opened database connection.
