These are tiny bugs with handling trailing \ I found (tested in 6.0 RC2):
1) when Location ends with \ you get "Unable to create 'E:\work\projects\foobar\'. Unable to create folder because it exists" (the folder really exists, but you don't get this error when there's no trailing backslash)
2) when Output or Result ends with \ you get full paths instead of relative paths in .ppj:
POC_PROJECT_OUTPUTDIR = E:\work\projects\foobar\output\#
POC_PROJECT_RESULTDIR = E:\work\projects\foobar\result\#
instead of
POC_PROJECT_OUTPUTDIR = output#
POC_PROJECT_RESULTDIR = result#
IMHO paths with trailing backslash should be handled in the same way as without it.
