go To Build =&gt; Configuration Manager . then check the deploy checkbox for the startup project . 
Ps. make sure to select your startup project by right clicking on the project =&gt; set as startup project

I&#39;m trying to get my app working in **Xcode 8.0**, and am running into an error. I know this code worked fine in previous versions of swift, but I&#39;m assuming the code for this is changed in the new version. Here&#39;s the code I&#39;m trying to run:

    let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)     
    UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    UIApplication.shared().registerForRemoteNotifications()

The error that I&#39;m getting is &quot;Argument labels &#39;(forTypes:, categories:)&#39; do not match any available overloads&quot;

Is there a different command that I could try to get this working?

What is the difference between ASP.NET Core Web (.NET Core) vs ASP.NET Core Web (.NET Framework)?

and does .NET Framework provide [similar performance][1] as to .NET Core?

I want the example controller below to return a status code 418 with no contents. Setting the status code is easy enough but then it seems like there is something that needs to be done to signal the end of the request. In MVC prior to ASP.NET Core or in WebForms that might be a call to `Response.End()` but how does it work in ASP.NET Core where `Response.End` does not exist?

    public class ExampleController : Controller
    {
        [HttpGet][Route(&quot;/example/main&quot;)]
        public IActionResult Main()
        {
            this.HttpContext.Response.StatusCode = 418; // I&#39;m a teapot
            // How to end the request?
            // I don&#39;t actually want to return a view but perhaps the next
            // line is required anyway?
            return View();   
        }
    }

How to return a specific status code and no contents from Controller?

I have a asp.net core application that uses dependency injection defined in the startup.cs class of the application:  

        public void ConfigureServices(IServiceCollection services)
        {

            services.AddDbContext&lt;ApplicationDbContext&gt;(options =&gt;
                options.UseSqlServer(Configuration[&quot;Data:FotballConnection:DefaultConnection&quot;]));


            // Repositories
            services.AddScoped&lt;IUserRepository, UserRepository&gt;();
            services.AddScoped&lt;IUserRoleRepository, UserRoleRepository&gt;();
            services.AddScoped&lt;IRoleRepository, RoleRepository&gt;();
            services.AddScoped&lt;ILoggingRepository, LoggingRepository&gt;();

            // Services
            services.AddScoped&lt;IMembershipService, MembershipService&gt;();
            services.AddScoped&lt;IEncryptionService, EncryptionService&gt;();

            // new repos
            services.AddScoped&lt;IMatchService, MatchService&gt;();
            services.AddScoped&lt;IMatchRepository, MatchRepository&gt;();
            services.AddScoped&lt;IMatchBetRepository, MatchBetRepository&gt;();
            services.AddScoped&lt;ITeamRepository, TeamRepository&gt;();

            services.AddScoped&lt;IFootballAPI, FootballAPIService&gt;();

This allows something like this: 

    [Route(&quot;api/[controller]&quot;)]
    public class MatchController : AuthorizedController
    {
        private readonly IMatchService _matchService;
        private readonly IMatchRepository _matchRepository;
        private readonly IMatchBetRepository _matchBetRepository;
        private readonly IUserRepository _userRepository;
        private readonly ILoggingRepository _loggingRepository;

        public MatchController(IMatchService matchService, IMatchRepository matchRepository, IMatchBetRepository matchBetRepository, ILoggingRepository loggingRepository, IUserRepository userRepository)
        {
            _matchService = matchService;
            _matchRepository = matchRepository;
            _matchBetRepository = matchBetRepository;
            _userRepository = userRepository;
            _loggingRepository = loggingRepository;
        }

This is very neat. But becomes a problem when I want to unit test. Because my test library does not have a startup.cs where I setup dependency injection. So a class with these interfaces as params will just be null. 

    namespace TestLibrary
    {
        public class FootballAPIService
        {
            private readonly IMatchRepository _matchRepository;
            private readonly ITeamRepository _teamRepository;
    
            public FootballAPIService(IMatchRepository matchRepository, ITeamRepository teamRepository)
    
            {
                _matchRepository = matchRepository;
                _teamRepository = teamRepository;

In the code above, in the test library, **_matchRepository** and **_teamRepository**, will just be **null**. :(

Can I do something like ConfigureServices, where I define dependency injection in my test library project?

I am attempting to create a custom User Control that is usable in the Acumatica Framework. Documentation is very limited so I was hoping someone may have some experience/examples of how best to implement?

It appears possible by creating a `WebControl` derived from `PXWebControl` and creating a global *JS* function with a matching name.

What is the difference between .NET Core and Mono?

I found a statement on the official site that said: &quot;Code written for it is also portable across application stacks, such as Mono.&quot;

My goal is to use C#, LINQ, EF7 and Visual Studio to create a website that can be ran/hosted on Linux.

Someone told me that he wanted it to be &quot;in Mono&quot;, but I don&#39;t know what that means. I know I want to use the .NET Core 1.0 with the technologies I listed above. He also said he wanted to use &quot;fast CGI&quot;. I don&#39;t know what that means either.

Can you help me make sense of all these terms and if my expectations are realistic?

Microsoft now has .NET Core, .NET Framework and Xamarin (Mono) in its family.

It seems to be a lot of overlap here. What&#39;s the difference between these types of .NET Platforms? When should I choose to use .NET Core in my project, instead of .NET Framework or Xamarin?

The following `MarkerClick` implementation works, perfectly fine. I could be able to open other Views via `ShowViewModel`

**View.cs**

    mMap.MarkerClick += MMap_MarkerClick;
   
    private void MMap_MarkerClick(object sender, GoogleMap.MarkerClickEventArgs e)
    {
       ViewModel.MapInfoSelected(e.Marker.Title);
    }

**ViewModel.cs**

    public void MapInfoSelected(string name)
    {
        ShowViewModel&lt;StudentViewModel&gt;(new { studentName = name});
    }

-------------------------------------

`InfoWindowClick` does not trigger to open other View.

**View.cs**

    mMap.InfoWindowClick += MMap_InfoWindowClick;

    private void MMap_InfoWindowClick(object sender, GoogleMap.InfoWindowClickEventArgs e)
    {
      ViewModel.MapInfoSelected(e.Marker.Title);
    }

**ViewModel.cs**

    public void MapInfoSelected(string name)
    {
     // it hits here, but does not hit `StudentViewModel` Init() method, the app is frozen and do nothing
        ShowViewModel&lt;StudentViewModel&gt;(new { studentName = name});
    }

I even tried the `SetOnInfoWindowClickListener` as follows, it also does not open the View. 

     mMap.SetOnInfoWindowClickListener(this);

     public void OnInfoWindowClick(Marker marker)
     {
         ViewModel.MapInfoSelected(marker.Title);
     }

**UPDATE:**

It even hits the `OnPause()` method, but still it does not call `StudentViewModel` Init() method if I use `InfoWindowClick` event

     public override void OnPause()
     {
       base.OnPause();
       mMap.InfoWindowClick -= MMap_InfoWindowClick;
     }

MarkerClick works but InfoWindowClick does not open ViewModel

I&#39;m rewriting my existing (swift) iOS physical therapy app &quot;On My Nerves&quot; to Xamarin.Forms. It&#39;s a timer app to help people with nerve damage (like me!) do their desensitization exercises. You have these &quot;fabrics&quot; (e.g. a feather) where each fabric has an &#39;x&#39; second countdown. When once fabric&#39;s timer reaches 0, a message box appears saying &quot;time&#39;s up&quot;. The user hits OK and the next fabric starts its countdown. Rinse and repeat for all fabrics in the list. Here&#39;s a [video showing the workflow][1]. Trust me on the UX in the video. 

Here&#39;s my [sample app code demonstrating this behavior][2]. 

The `DoSomethingForNow` method (forgive my naming strategy) is the callback from the NotificationService (see line 65 - not enough SO rep points for direct link) that is created when the timer starts, in case the app gets the background.

The specific call that is not working on Release mode on Device is at line 115 

    Device.BeginInvokeOnMainThread(
                    async () =&gt; await ShowAlertAndWaitForUser(currentFabricCount));


The `async () =&gt; await ShowAlertAndWaitForUser(currentFabricCount))` works as expected in Debug and Release configuration on iOS Simulator, and in Debug configuration on the device. 

However, the message box indicating time is up **does not appear in Release config on the physical device**. I cannot figure out why `Device.BeginInvokeOnMainThread()` doesn&#39;t work in Release config on device. What is going on?  

*Side note re using* ***`Device.StartTimer()`***

*The reason why I switched from* *`Device.StartTimer()`* *to James&#39;s FrenchPressTimer solution (see jamesmontemagno/FrenchPressTimer) early on is because I need a way to cancel / stop / whatever a* *`Device.StartTimer()`* *in case the user needs to pause or stop the countdown on the app.*

*The* *`Device.StartTimer()`* *code works great for me on all configurations on both simulator and device and thankfully someone showed me how to cancel a Device.StartTimer (thanks!). If you want to see this working solution, check out saraford/Device-StartTimer-Working-Xamarin on GitHub.*
 
My specific question is why doesn&#39;t `Device.BeginInvokeOnMainThread()` display a message box when invoked from a notification callback in Release config on a physical device.

I&#39;ve also tried the different linker combinations. No effect.

I&#39;m attempting to build my first F# Android project in Visual Studio 2017 *(Community Edition)*.

Immediately after creating a new project by using the F# - Android - Blank App template, the error window in Visual Studio displays the following message:

&gt; The project Foo is missing Android SDKs required for building. Double-click on this message and follow the prompts to install them.

No amount of double-clicking on the message causes prompts to appear.

I can&#39;t find an obvious place to download the Android SDK from:

The SDK manager that I remember from a while ago seems to have disappeared from the Android developer website.

I&#39;ve installed Android Studio, which seemed to download some Android SDKs, but Visual Studio still can&#39;t seem to find whatever it&#39;s looking for.

Assuming we have a database project called `MyDatabase` then a file called `MyDatabase.jfm` appears in the root of the project directory.

- It is exclusively locked while the project is open in Visual Studio
- It is a binary file
- It has only started appearing recently (past couple of days)

I have done a Google search, which has not offered any insight. There are some references to some old software, but most of the results are spam/trojanware. I have also looked in SO, but that has not produced any results either.

**Does anyone know what it is and why it&#39;s there?**

The plan is to add it to the [gitignore file for Visual Studio][1], but I need to know what it is first to submit the PR...

**UPDATE**

This is now breaking the Team Explorer Changes view. There are no changes being shown with the following from the Output window:

[![Screenshot of the error from the output tab][2]][2]

As such I will be adding the file to the .gitignore file and [submitting the PR][3]. It would be good to eventually learn what this file is and where it came from...

I&#39;ve also tried the other solutions mentioned in that link to no avail.

 - **Deleting nuget.config** 
 - **Deleting packages.config**
 - **Updating nuGet Package Manager.**

Also, I&#39;m able to see the nuGet Packages at the solution level and other projects within this solution.

And, if I go to Package Manager Console (Tools -&gt; NuGet Package Manager -&gt; Package Manager Console), I can&#39;t see the projects having this issue in the project drop down, but I see the other projects in the solution.

Each time I try to install the **DotNetCore.1.0.0-VS2015Tools.Preview2.exe** package I get an error saying the following:

&gt; Setup Failed One or more issues caused the setup to fail.  Please fix
&gt; the issues and then retry setup.  For more information see the log
&gt; file. Setup has detected that Visual Studio 2015 Update 3 may not be
&gt; completely installed.  Please repair Visual Studio 2015 Update 3, then
&gt; install this product again.

When I look into the log file, I find the following line which seems to be causing the error during install:

&gt; Condition &#39;WixBundleInstalled OR NOT(((VS2015CommunityUpdateVersion &lt;&gt;
&gt; VS2015UpdateVersion) AND (VS2015CommunityExists) AND
&gt; (VS2015UpdateVersionExists)) OR ((VS2015ProfessionalUpdateVersion &lt;&gt;
&gt; VS2015UpdateVersion) AND (VS2015ProfessionalExists) AND
&gt; (VS2015UpdateVersionExists)) OR ((VS2015EnterpriseUpdateVersion &lt;&gt;
&gt; VS2015UpdateVersion) AND (VS2015EnterpriseExists) AND
&gt; (VS2015UpdateVersionExists)) OR ((VS2015WebExpressUpdateVersion &lt;&gt;
&gt; VS2015UpdateVersion) AND (VS2015WebExpressExists) AND
&gt; (VS2015UpdateVersionExists))) OR (SKIP_VSU_CHECK=1) OR
&gt; (WixBundleAction=2)&#39; evaluates to false.

A simple repair of Update 3 has not resolved the issue, so I was attempting to resort to an uninstall/reinstall of the update.  When going through 

&gt; Control Panel &gt; Programs and Features &gt; View Installed updates

 to uninstall the update, it jumps right to the &quot;`Setup Completed`&quot; screen saying that all of the components have been uninstalled without any progress screen.  Then when I attempt to run the Update 3 installer it says the Update is already installed.

I then tried using Revo Uninstaller but the same thing happens after cleaning out folders and registry items.

I even tried doing an `/uninstall /force` on the package but to no avail.  It seems something is remaining stuck somewhere that keeps the update registered.  

Any suggestions?
