Compiler Warning (level 1) CS3023

  • Article

CLSCompliant attribute has no meaning when applied to return types. Try putting it on the method instead.

Function return types are not checked for CLS Compliance, since the CLS Compliance rules apply to methods and type declarations.

Example

The following example generates warning CS3023:

// C3023.cs

[assembly:System.CLSCompliant(true)]
public class Test
{
    [return:System.CLSCompliant(true)]  // CS3023
    // Try this instead:
    // [method:System.CLSCompliant(true)]
    public static int Main()
    {
        return 0;
    }
}
