what is [STAThread]?

may i know what is [STAThread] for ? it will always be generated in Visual Studio.net when i create a C# console project but not in other IDE , wonder what is it used for. thanks

That's just a guess -- I actually have no idea --, but I think it means "Single-Threaded Application Thread", which is an attribute that would allow the .NET framework to know that this entry-point leads to a single-threaded application and allows it to disable some overheaded linked to the multithreading support.

And rule number two: always look at the documentation before trying to explain something on a forum. On MSDN, I found that:

STAThreadAttribute Class (.NET Framework)
Indicates that the COM threading model for an application is single-threaded apartment (STA).

The link leads to the documentation of the attribute.
