Originally created by @mkitzan on GitHub (Nov 28, 2019).

Environment

Windows build number: 0.0.1.0 Dev Build
Windows Terminal version (if applicable): 10.0.18363

Steps to reproduce

Invoke Profile::GetGuid on a Profile object without a GUID.

Expected behavior

GetGuid is specified as noexcept, the compiler and users expect the function to never throw.

Actual behavior

Exception thrown by a noexcept function.

New function semantics need to be decided for GetGuid and functions affected by GetGuid no longer being noexcept. Could be fixed by removing the noexcept specifier from the function and all affected functions.
