I'm using python 2.7 and django 1.6. However, PTVS generates the project/app according to django 1.4. I believe this is because the default "References" being "Django 1.4".
How I can change it to "Django 1.6"? I tried "Add Referrence->Web Platform Installer" but it seems only having "django 1.4".
Thanks
