There was a problem hiding this comment.
If you were to invert this condition, you wouldn't need the unreachable throw:
if(!TryLoadMsQuic(outIntPtrmsQuicHandle)||!TryOpenMsQuic(msQuicHandle,outQUIC_API_TABLE*apiTable,outopenStatus)){ThrowHelper.ThrowIfMsQuicError(openStatus);}returnnewMsQuicApi(apiTable);You could also have a ThrowMsQuicError that was unconditional. Or just use throw GetExceptionForMsQuicStatus(openStatus);.

This PR improves diagnostics when allocating MsQuicApi instance, this was useful when investigating #74952 and would be nice to get into .NET 7 as part of #74931.
