Nullability of reference types in type of parameter 'other' of 'bool WorkingDirectoryFile.Equals(WorkingDirectoryFile other)' doesn't match implicitly implemented member 'bool IEquatable<WorkingDirectoryFile>.Equals(WorkingDirectoryFile? other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'value' of 'object EnumDisplayNameConverter.Convert(object value, Type targetType, object parameter, CultureInfo culture)' doesn't match implicitly implemented member 'object? IValueConverter.Convert(object? value, Type targetType, object? parameter, CultureInfo culture)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'parameter' of 'object EnumDisplayNameConverter.Convert(object value, Type targetType, object parameter, CultureInfo culture)' doesn't match implicitly implemented member 'object? IValueConverter.Convert(object? value, Type targetType, object? parameter, CultureInfo culture)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'value' of 'object EnumDisplayNameConverter.ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)' doesn't match implicitly implemented member 'object? IValueConverter.ConvertBack(object? value, Type targetType, object? parameter, CultureInfo culture)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'parameter' of 'object EnumDisplayNameConverter.ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)' doesn't match implicitly implemented member 'object? IValueConverter.ConvertBack(object? value, Type targetType, object? parameter, CultureInfo culture)' (possibly because of nullability attributes).

Possible null reference argument for parameter 'sourceArray' in 'void Array.Copy(Array sourceArray, int sourceIndex, Array destinationArray, int destinationIndex, int length)'.
