title: Any way to include files from a non main project in the outpot folder?
body: <p>My question is somewhat similar to an already existing one:
  <a href="https://stackoverflow.com/questions/16785369/how-to-include-other-files-to-the-output-directory-in-c-sharp-upon-build">How to include other files to the output directory in C# upon build?</a></p>
  
  <p>In my case though I'm not trying to include files of the mainproject into the output folder, but of another project in the same application (thus 2 projects A being the mainproject and B being the other one).</p>
  
  <p>What I want is that whenever I compile the application A is giving the .exe  while some files (.xml) in the B project are put into a folder in the output alongside the .exe from A.</p>
  
  <p>Now I've tried the method from the similar question with changing the output type of the files in B. It works fine when I compile B (they land in the appropriate folder there). But when I compile the project as a whole (as A is the "main"), I run into the problem that the .dll (or whatever I decide to compile B as) is created BUT the folder and files from B are not existent.</p>
