title: How to use a DLL create from txt and compiled with Developer Command Prompt?
body: <p>I generate cs files ( classes ) with the same namespace (EDR_Config). After I generate them, I compile them using Developer Command Prompt for VS2012.</p>
  
  <p>The command line is :
               <code>csc /target:library /out:EDR_Config.DLL AssemblyInfo.cs 
              EdrClassInitializator_CFG.cs EdrEquationsDecoder_CFG.cs EdrTreeCreator_CFG.cs</code></p>
  
  <p>Everything looks great till I add a reference to the c# project. When I try to write
  <code>using EDR_Config;</code>
  it tell me: Error   1   The type or namespace name 'EDR_Config' could not be found (are you missing a using directive or an assembly reference?)<br>
  Why is that happening? Or how can I solve it?</p>
