I have version 7.x installed and downloaded and just downloaded the latest 8.x project manager. It's only a single exe. Should I just copy the 8.x exe over top of the 7.x one or is there a full install I'm missing?
I have folder for each version
If you create a project it will create an _EmtpyPorject folder with a blank project you can use to see what dll are supposed to be in the project
If you keep it seperate you can not only compare the 8.0 bin dll to what you have but also what should be on youir 7.0 project.
Sometimes you upadate and forget to delete stuff.
Also I keep my languages files in the corresponding version.
So no - My personal answer would be to keep it in seperate folders!
See step 1. b a on that page. This is easy for me if I keep it in seperate folders.
Just my 2 cents
Yeah when you realize the project manager just facilitates "Copying" the dlls from emptyproject into the selected projects bin folder...updating Sitefinity becomes trival :)
(It also updates the webconfig now too though when required)
