Failed to load toolbox item, It will be removed from Toolbox

Picture Linked to Title, I was try to:

  • Clean and Rebuild won’t work
  • Project built in x86
  • Restart V.S doesn’t work
    I just:
  1. Created Form and userControl by Default name
  2. Linked To Windows and Advanced to "main"
  3. Added code in Form.cpp to fix Designer error and restart V.S
  4. Try to Drag userControl but no luck ;(
