Duplicate Item "Resources" parameter error

Duplicate Item "Resources" parameter error

• JurgenT

  Thanks for the heads up with this. I recently noticed the new partial class support and how it helps to separate classes into several physical files - great!
  
  Using the <DependentUpon> node in the project XML I was able to add additional files for a form and split functionality into these files to reduce the volume of code within the one file.
  
  To push the envelope I created two forms, I then made one of the forms a private inner classes within the other 'parent' form.
  
  viz.
  namespace TestApp1 {
  public partial class Form1: Form {
  private partial class MyDialog : Form {
  public MyDialog() {
  InitializeComponent();
  }
  }
  }
  }
  
  Now when I compile I get this error:
  
  The item "obj\Debug\TestApp1.Form1.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter. TestApp1
  
  If I modify the form as follows...
  
  namespace TestApp1 {
  //public partial class Form1: Form {
  private partial class MyDialog : Form {
  public MyDialog() {
  InitializeComponent();
  }
  }
  //}
  }
  
  
  All is well. Is this supposed to work and I have missed something or am I pushing my luck :-)
  
  Thanks in advance for any assistance!
  
  Andrew.

  This usually happens when you copy a form without renaming types. Check the naming in the cs files and rename duplicate classes.

  You can open the project file. There will be a duplicate entry for the .cs, .designer.cs, and .resx file for file

  It happened to me when I overwrote a control with another abd built it.

  Nevermind, I just combined the two files and it solved the problem.
