Salut chers Amis , j
J'ai vraiment besoin de votre aide, comment je pourrais éliminer cette erreur :

Error 1 Unable to copy file "obj\x86\Debug\WindowsFormsApplication5.exe" to "bin\Debug\WindowsFormsApplication5.exe". The process cannot access the file 'bin\Debug\WindowsFormsApplication5.exe' because it is being used by another process. WindowsFormsApplication5
Merci.
