Compiler Warning (level 2) CS0440

Defining an alias named 'global' is ill-advised since 'global::' always references the global namespace and not an alias

This warning is issued when you define an alias named global.

Example

The following example generates CS0440:

// CS0440.cs
// Compile with: /W:1

using global = MyClass;   // CS0440
class MyClass
{
    static void Main()
    {
        // Note how global refers to the global namespace
        // even though it is redefined above.
        global::System.Console.WriteLine();
    }
}
