Currently, the bug exists on .NET Framework, but not on .NET (in the past it was on some versions of .NET Core IIRC).

The change eliminates the try-catch, so we get two benefits:

1. It does not interrupt the debugger because an exception is being thrown.
2. It is faster — on both frameworks, though the gain is obviously the biggest on .NET Framework. Even then this code executes only once per process, lazily, so the gain is a mere ~25 µs, so negligible.

The patch was sitting in my stash for 7 years, so it's time to submit it or drop it.

Thanks! Every little bit helps. 😄
