## What is the current behavior?
<!-- Please describe the current behavior that you are modifying, or link to a relevant issue. -->
The `ThrowHelper` class exposes static throw-helper APIs that mirror the existing constructor for all the supported exception types. In the previous PRs though I had missed the parameterless constructors, so there were no APIs for that in the `ThrowHelper` class.

## What is the new behavior?
<!-- Describe how was this issue resolved or changed? -->
`ThrowHelper` now exposes a parameterless overload for all the supported exception types that are exposed.
