Multithread Form Application (.NET 4.0)

I'm currently working on a solution that has two projects, a console and a form application. The console application is the main entry point to my application, and from the console the user would run the form application.

The problem is, when the user boots the form application the rest of the business logic (from the console app) won't run until the form is closed. My first thought was to use a background worker fo开发者_运维知识库r the form, but the business logic in the form project already uses a background worker (and I only have two CPUs...). Perhaps this could be my ignorance for multithreading, but is there a way to do this?

Any thoughts are much appreciated! Cheers

Well, this is pretty unusual. In general, it doesn't make a lot of sense to provide the user with a nice GUI and still leave a console window up and interactive.

But yes, calling Application.Run() or Form.ShowDialog() is going to block the thread. It has to, the message loop needs to be running to keep the GUI alive. If you do this, be sure to put the [STAThread] attribute on the Main() method.

The only other decent alternative is to start a thread. This isn't a problem, a UI thread doesn't burn any CPU cycles. Code only ever runs when the user does something, it's otherwise idle 99% of the time. Be sure to call the thread's SetApartmentState() method before you start it, STA is required.
