What does it mean by " <STAThread()> _"

[bnathvbdotnet]

<STAThread()> _
Shared Sub Main()
Application.Run(New Customers)
End Sub 'Main

Customer is the name of the windows form

I read some thing in help in regards to COM Interop..but in easy words what does STAThread mean?

Any explanation is very helpful.

thanks

Single-Threaded Apartment threading model

It signifies to the COM InterOp layer that STA is the threading model used. If you don't have any COM InterOp in your app, then you don't need to worry about it.

"Com Interop" means If I am using any com dll's in my vb.net project, the .net should be able to communicate with dll (written in previous versions of vb) . Is that what it means?

thanks
