vb.net - VB2010 Unable to open two applications derived from same code at the same time -


this may simple question, i'm not sure of search terms find answer.

i have 2 winforms applications have been derived same code. 1 supersedes other, have older vb app legacy information.

the problem is, if 1 app open, when icon of other app clicked, nothing happens. open app's window becomes selected has been opened. nothing else.

what happen both apps can open @ same time. reference different db's there's not clash there.

i thought might name spaces, changed those, no avail.

any thoughts, i'm sure simple answer.

mark

look @ project settings (double click on "my project" in project explorer).
in application-tab you'll find setting "create single instance application"
(i'm translating german version, may slighlty different).

better alternative:
basicly useful keep setting , go alternative: in same spot, find button "assembly information". click on , change first number of "assembly version". older , newer versions 2 different programs windows , run parallel.
