I just installed PTVS 2.1 and I opened my Django project that was working with PTVS 2.0.
Now, IntelliSense does not recognize any of my apps. All local import statements have this error:
Unable to resolve "app.module". IntelliSense may be missing for this module.
However, it will not complain if I import "project.app.module".
solves the problems.
