Hi, I coded a remote code execution exploit for visual studio 2005 and below. If you open a solution and you click on the Form1.cs file the code inside the UserControl1_Load function is executed. You can code your backdoor inside this function. Basically the exploit only start a calc.exe application. Have a look at http://www.securiteam.com or http://www.priestmaster.org/exploits greets, priestmaster.
