i got code here , assume since says can copied/pasted have improperly set kinect project.
edit:
this have changed code to:

program: 'c:\users\\documents\visual studio 2010\projects\1\1\1\obj\debug\1.exe' not contain static 'main' method suitable entry point
welcome stackoverflow , please consider reading faq in order best result , you're facing first error because class name not match it's constructor ! should change mainwindow() in line 48 jarvis()
public jarvis() { initializecomponent(); initializekinect(); } and source has mentioned , need add 3 textboxes project name of textbox1 , textbox2 , textbox3
if don't need textboxes change code whatever desire
- update : try start new project , add class project paste code inside class , use class in project , please keep in mind copying , pasting bunch of code not helpful unless know you're doing , , can't start project , paste other codes instead of it's own functions , classes , expect app run , please consider writing code self better option , in case you'll desired result faster !
