seems

internal static bool IsEventBackingFieldName(string fieldName, string eventName, out int suffixLength)
{
	suffixLength = 0;
	if (fieldName == eventName)
		return true;
	var vbSuffixLength = "Event".Length;
	if (fieldName.Length == eventName.Length + vbSuffixLength && fieldName.StartsWith(eventName, StringComparison.Ordinal) && fieldName.EndsWith("Event", StringComparison.Ordinal))
	{
		suffixLength = vbSuffixLength;
		return true;
	}
	return false;
}

caused this error
