I know and I can program any AVR microcontroller with Arduino IDE and Arduino Uno board. Can I use Arduino board with AVR Studio? Or I have to buy an AVR Development board?
There is an Arduino plugin available for AVR Studio, which allows you to upload sketches to an Arduino, just like you would with the Arduino IDE. I think this also enables you to upload plain C/C++ files created with the standard AVR tools.
Alternatively, if you have an AVR ISP programmer, you can use this to upload compiled C/C++ to the Arduino from AVR studio without needing the Arduino plugin.
