Updated: July 20, 2015

For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

Type of 'variable' is not CLS-compliant

A public, protected, or protected internal variable must be of a type that is compliant with the Common Language Specification (CLS). For more information on CLS Compliance, see Language Independence and Language-Independent Components.

The following example generates CS3003:

// CS3003.cs  
  
[assembly:System.CLSCompliant(true)]  
public class a  
{  
    public ushort a1;   // CS3003, public variable  
    public static void Main()  
    {  
    }  
}
