Hello. I am currently developing an application using .NET 7.0 because of Native AOT.

While trying to optimize string garbage using ZString, it worked fine in the debug environment, but crashed when built with Native AOT.

After receiving the ZString source code and building it myself, I checked the warning message and it said that using Enum.GetValues() is not compatible with Native AOT.

I think you should use Enum.GetValuesAsUnderlyingType() (added in .NET 7.0) or just use ToString().
