So, just to be clear, the *program* works fine if you have a constant `false` controlling the `if` - the problem is that the debugger is unable to deal correctly with variables scoped to the `else` clause.  Is that a fair summary?

WTF? It's normal again...

Has anyone heard of this kind of wonkiness before?

Yes, I have.  Per discussion with a tech of MSDN, it's a bug in the Debugger.

Yes.

"if (false)" results in locally scoped variables declared in else clauses not being available to the debugger, but still functioning properly in the software.

Here's something you can copy & paste in VS to have a quick look:
Code: C#
  1. string test1a = "Hello";
  2. int test2a = 4;
  3. string test1c;
  4. int test2c;
  5. if (false)
  6. {
  7. }
  8. else
  9. {
  10.     string test1b = test1a + " world!"; // can't see 1b
  11.     int test2b = test2a * test2a; // can't see 2b
  12.     test1c = test1b; // can see 1c, not 1b
  13.     test2c = test2b; // can see 2c, not 2b
  14.     Console.WriteLine("Break here :" + test1b + test2b.ToString()); // this works as expected, but can't see during debugging
  15. }
  16.
