GetUtcStartOfWeekInTimeZone issue about msgraph-sample-aspnet-core

[jasonjoh]

Thanks for reporting. For the first issue, that's a known limitation - I didn't do any logic to detect the proper start of week for the user - it's just hard coded to Sunday. It looks like you've already discovered that bit and have adjusted it.

That assumption of Sunday carries over into the view, which is causing the shift you're seeing. In CalendarViewModel, the events are sorted into buckets by the day of the week. I'm guessing that since you changed _startOfweek to Saturday, code like this is causing the shift:

It's the model for Saturday, but it's getting events for Sunday.

Hi,
I posted your code in CalendarController > GetUtcStartOfWeekInTimeZone, I didn't make any changes.
Sunday it's ok for me as first day of the week but that function return Saturday.

I fixed like this
CalendarController

[AuthorizeForScopes(Scopes = new[] { "Calendars.Read" })] public async Task<IActionResult> Index() { try { var userTimeZone = TZConvert.GetTimeZoneInfo( User.GetUserGraphTimeZone()); var startOfWeek = CalendarController.GetUtcStartOfWeekInTimeZone( **DateTime.Today**, userTimeZone);
I change it in DateTime.Now

and in GetUtcStartOfWeekInTimeZone I return the date
return TimeZoneInfo.ConvertTimeToUtc(unspecifiedStart, timeZone).**Date**;
