If I have a static ImmutableHashSet field, such as:
Quote:private static readonly ImmutableHashSet<DayOfWeek> Days = [DayOfWeek.Wednesday, DayOfWeek.Thursday];
This can cause the exception:
Quote:System.ArgumentException: Value does not fall within the expected range.
at System.Runtime.CompilerServices.RuntimeHelpers.GetSpanDataFrom(RuntimeFieldHandle fldHandle, RuntimeTypeHandle targetTypeHandle, Int32& count)
at System.Runtime.CompilerServices.RuntimeHelpers.CreateSpan[T](RuntimeFieldHandle fldHandle)
The tests succeed in the VS test runner.
To cause this error, I find that the following has to be true:
1. The field must be static.
2. The field must be of type ImmutableHashSet. Changing it to HashSet causes NCrunch to succeed.
3. The field must be accessed from a private method.
4. The private method must be accessed by NCrunch from a public method.
I thought that possibly
this problem was related, but there you say that disabling RDI should resolve the problem, but in my case I have RDI disabled and have disabled it in-line in my tests, but the problem persists.
Minimal solution:
https://github.com/garypendlebury/NCrunchFault
My environment: Visual Studio 2022 (17.14.0 Preview 2.0); NCrunch 5.12.0.10.
Any idea what's causing this?
