+Summary: System.InvalidCastException during compile
+
+The following program doesn't compile:
+
+----------
+public class App
+{
+    public static void Main()
+    {
+            for( uint i = uint.MinValue;
+                i < uint.MaxValue - ushort.MaxValue;
+                i += ushort.MaxValue );
+            // for( uint i = uint.MinValue;
+            //     i < uint.MaxValue - (uint) ushort.MaxValue;
+            //     i += (uint) ushort.MaxValue );
+    }
+}
+----------
+
+The compiler diagnoses:
+

+Using explicit casts the compiler accepts the code (see the commented 
+lines).
