Compiler Warning (level 1) CS1616

Option 'option' overrides attribute 'attribute' given in a source file or added module

This warning occurs if the assembly attributes AssemblyKeyFileAttribute or AssemblyKeyNameAttribute found in source conflict with the KeyFile or KeyContainer command line option or key file name or key container specified in the Project Properties.

For the example below, assume you have a key file named cs1616.snk. Generate this file with the command line:

sn -k CS1616.snk  

The following sample generates CS1616:

// CS1616.cs  
// compile with: /keyfile:cs1616.snk  
using System.Reflection;  
// To fix the error, remove the next line  
[assembly: AssemblyKeyFile("cs1616b.snk")]  // CS1616  
class C  
  public static void Main()
