no changes after compiling

Question

When I compile my Silverlight prjoect changes aren't made. And when I create a new Project no xap file is generated. neither in clientbin nor bin debug/release. I cleared cache ...I tried different browsers. Nothing works

Answer 1

i figured out myself. in vs2010 on options->projects and solutions->build and run->On run, when projects are out of date it was set to never build.

i have no idea how that was done because i never changed anything there.
