title: MSBuild behavior is pretty unclear?
body: <p>So I started to work with MSBuild, cause it seemed as really good solution for my needs, but there is one particular problem I noticed and I figured workaround, but would like an absolute solution.</p>
  <p>So problem is following, when I run MSBuild on project, and run it again(without changing anything in project), it removes all .dll's and I can't run project's exe anymore, but when I change anything in project it compiles perfectly fine and missing .dll's are again there. Is there some flag I need to add when running MSBuild or anything else I am clearly missing?</p>
