ion.calendar | Calendar and Datepicker jQuery plugin | Calendar library

I am trying to convert HijriCalendar to Gregorian Calendar in Xamarin Forms app. However, it seems that Xamarin Android is not happy with it. I haven't test it in Xamarin iOS. I am using code from Cannot convert from Hijri Date to Gregorian date (c#) and I am getting below exception when instantiating the HijriCalendar object in line

In my solution, I have 3 projects. One of them is an Xamarin.Android project, the other 2 are PCLs. If I try to clean or build any of the projects, it hangs and I have to restart VS. But if I unload the Android project, and restart VS, I can clean/build the other 2 projects. When I try to clean/build any of the projects, and it hangs, there is nothing in the build output other than "Building MyProjectName (Debug)", even if I change the build verbosity to Diagnostic.

I didn't have this problem before and it was working fine. It started after I uninstalled VS and reinstalled it to the latest version (8.7). I was on 8.6 before. But even if I install 8.6, or an older version, the problem still persists, so I don't know what happened...

EDIT

If I create a new Android project in a new solution, it will build and I don't have this problem. I have a hunch that it has something to do with the NuGet packages, but I can't figure it out. My colleague is running the same solution on his machine and doesn't have any problems with it. I even tried reinstalling everything (VS4Mac, Android SDKs, Mono Android etc).

In case it helps, this is the packages.config file in the Android project:

I want access the users iCloud Calendar events in an app for macOS. While researching I have found some tutorials for iOS but I couldn't find one that works on macOS. I tried to understand Apples Developer Documentation for EventKit but didn't manage to get it running.

Thats what I did:

1 - Accessing the Event Store

1.1 I have changed the 'com.apple.security.personal-information.calendars' key to YES in the entitlements file (Stack Overflow Question regarding this).

Screenshot of the .entitlement of the Project:

1.2 Afterwards I tried to request the access (in the viewDidLoad)

I have a string field which contains a date which I cast as date. I need to group it using LINQ by week. My eventual goal is to have it as

YEAR
WEEK
BeginDateOfWeek (week starts on Monday)

BeginDateOfWeek would actually be used in the reports. Year and week are there to feed a function (not written yet but will be once I figure this out) which would determine the date information in BeginDateOfWeek.

However when I group by this date field as YEAR and WEEK with both functions called i I get:

YEAR=2020, WEEK= generated method

I did a for each and sure enough every week is listed as WEEK=generated method.

So I tried renaming the function (just spitballing on what is happening so I tried that) in the join clause to j and I get the error:

"Error BC36621 'Equals' cannot compare a value of type 'Function (i As Object) As Integer' with a value of type 'Function (j As Object) As Integer'."

So if anyone could help I would be so grateful. This is vb.net (c# solutions are fine) and NOT Linq To Entites but regular LINQ. I am really at wits end.

I upgraded my .net core 2.2 web api to .net core 3.1. I am now able to run it from console using dotnet myapi.dll, however when I try to host it on ISS, I get following exception.

I have installed AspNetCore Module V2 and this module is throwing exception and I am not able to understand the missing part.

Autofac.Core.DependencyResolutionException: An exception was thrown while activating ?:Microsoft.Extensions.Hosting.IHostedService[] -> Microsoft.AspNetCore.Hosting.GenericWebHostService -> Microsoft.AspNetCore.Server.IIS.Core.IISHttpServer. ---> Autofac.Core.DependencyResolutionException: An exception was thrown while invoking the constructor 'Void .ctor(Microsoft.AspNetCore.Server.IIS.Core.IISNativeApplication, Microsoft.Extensions.Hosting.IHostApplicationLifetime, Microsoft.AspNetCore.Authentication.IAuthenticationSchemeProvider, Microsoft.Extensions.Options.IOptions``1[Microsoft.AspNetCore.Builder.IISServerOptions], Microsoft.Extensions.Logging.ILogger

Following is my Program.cs

I want to implement this nice calendar chart on my website.

https://developers-dot-devsite-v2-prod.appspot.com/chart/interactive/docs/gallery/calendar

Assume the client performs an ajax request, on page load, and the server queries data from the database and responds with a multidimensional array in JSON Format.

How can i loop through to update the map?

I've upgraded my solution from asp.net core 2.0 web app to 2.1 and in one of my class libraries I'm using 'Microsoft.NET.Sdk.Razor' SDK.

• Rebuilding the solution from VS works
• Publishing the web project from command line using 'dotnet publish' works
• Publishing the web project from VS fails. The error output suggests that some of my project in solution is not included when publishingthe library with razor views.
• When I remove Microsoft.NET.Sdk.Razor and use just 'Microsoft.NET.Sdk' publishing from VS works.

• MyProject.DataAccess.csproj (netstandard2.0, nuget refereces Microsoft.EntityFrameworkCore.SqlServer 2.1)
• MyProject.Mail.csproj (netcoreapp2.1, Microsoft.NET.Sdk.Razor, references MyProject.DataAccess.csproj)
• MyProject.Shared.csproj (netcoreapp2.1, Microsoft.NET.Sdk, references MyProject.DataAccess.csproj)
• MyProject.Web.csproj (netcoreapp2.1, Microsoft.NET.Sdk.Web, references MyProject.Mail.csproj and MyProject.Shared.csproj, nuget reference Microsoft.AspNetCore.App);

The log file says:

I've written a Xamarin UWP (Universal Windows) app targeting Windows 10 build 16299. Currently I'm syncing data within the app and storing it in a realm database for offline use. I would like to move the sync code to a background task so it can run it in a schedule, updating data in the background. I added a new project of type Windows Runtime Component also targeting Windows 10 build 16299. Added realm and newtonsoft.json as nuget packages. When I try to build the project I get a build error. How can I solve the error?

Sample project can be found here https://github.com/GuidoNeele/RealmWindowsRuntimeComponentTest

How to you get the interface identifier (IID) for an interface from a *.winmd file when using IMetadataImport?

e.g. Windows.Globalization.ICalendar: {CA30221D-86D9-40FB-A26B-D44EB7CF08EA}

A good example is Windows.Globalization.ICalendar interface. It's IID is CA30221D-86D9-40FB-A26B-D44EB7CF08EA.

You can find it in the source Windows.Globalization.idl file:
