title: Visual Studio NuGet: Why dependent package's .targets file is not executed?
body: <p>I have two NuGet packages, one depends on another. 
  When i install the package which depends on another package (both of them have .targets in build folders) the .targets file of installed package is executed, but the "parent" package's .targets is not getting executed.
  If i will manualy install both of them - both .targets work as expected.
  Can somebody explain me why the hierarchy of packages not works here?
  Is there some workarounds about it?</p>
