title: Visual Studio Property Pages Environment Variables
body: <p>If you right click on a project in solution explorer and go to General -> Debugging there is an Environment section where you should be able to set environment variables using the syntax NAME=VALUE. My problem is that if I try to create a new environment variable there it doesn't seem to actually work or get set. Does anyone have any experience with this? I just want to set an environment variable so I can use it in custom build steps like this:</p>
  
  <p>environment variable</p>
  
  <pre><code>LANGUAGE_VAR=en_us
  </code></pre>
  
  <p>custom build step</p>
  
  <pre><code>copy $(InputPath) $(outDir)\%LANGUAGE_VAR%\$(InputFileName)
  </code></pre>
  
  <p>Something similar to that. 
  This MSDN page is useful but I can't get it to work:
