@EgorBo @jakobbotsch Note that according to the calendar, today is code complete day for the June release of .NET 10. So you might want to get this PR merged today. Sorry for the last minute notification. |

Customer Impact
The JIT compiler could make invalid assumptions regarding the
default:case inswitchstatements concerning the possible ranges of the checked variable. This could lead to incorrect constant folding and branch removal. The original bug reproduction is available here: #122254Regression
Regressed via #113998 JIT optimization.
Testing
A test is added.

Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older versions.
