Compiler Error CS1044

Cannot use more than one type in a for, using, fixed, or declaration statement

The compiler found an invalid statement.

The following sample generates CS1044:

// CS1044.cs
using System;

public class MyClass : IDisposable
{
   public void Dispose()
   {
      Console.WriteLine("Res1.Dispose()");
   }

   public static void Main()
   {
      using (MyClass mc1 = new MyClass(),
             MyClass mc2 = new MyClass())   // CS1044, remove an instantiation
      {
      }
   }
}
