I have a new project to start and I want to use 1.6, but I don't want to upgrade all my old projects that use 1.5.



So my question is, does a project with 1.5 references behave when you upgrade the development environment to 1.6 or once 1.6 is installed and I want to update a project, does it have to be updated to 1.6?



Thanks.
