Hi Bassel, Ruby provides its own support for asynchronous operations in its Thread class:
Thread.new do puts "howdy!" end If you specifically need to run a .NET delegate asynchronously, you can call its invoke method within this structure: Thread.new do my_action.invoke end More info on Ruby's Thread class: http://corelib.rubyonrails.org/classes/Thread.html Does that meet your needs?
