Hi to all,
I want to open SaveFileDialog Box. But am getting the Error :

Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process.

I am Developing the project using WPF and VS2010. Developed UI Using WPF. At the manager Layer I tried to Open SaveFileDialog Box.
I tried To set the [STAThreadAttribute] and [STAThread] attributes but I was not able to implement that can any one help me please.
