Starting with [C# for Visual Studio Code Extension 1.23.8](https://github.com/OmniSharp/omnisharp-vscode/releases/tag/v1.23.8) this is supported when `Editor: Format On Type.` setting is enabled.

Settings can be found in the menu under `File/Preferences/Settings` (Windows/Linux) / `Code/Preferences/Settings` (macOS). The required setting is available under `Text Editor/Formatting`.

This feature is not available out-of-the-box with VS Code, but like most features is available via third-party extensions. As of the time of this answer, here is a popular extension that provides some XML comments support to VS Code:

[C# XML Documentation Comments Support for Visual Studio Code][1]

If that extension doesn&#39;t work for you, you may be able to find alternatives by searching the [VS Code Marketplace][2]

This was discussed by k8s maintainers in https://github.com/kubernetes/kubernetes/issues/7438#issuecomment-97148195:

&gt;&gt;  Allowing users to ask for a specific PV breaks the separation between them
&gt;
&gt; I don&#39;t buy that.  We allow users to choose a node.  It&#39;s not the common
case, but it exists for a reason.

How did it end? What&#39;s the intended way to have &gt;1 PV&#39;s and PVC&#39;s like the one in https://github.com/kubernetes/kubernetes/tree/master/examples/nfs?

We use NFS, and PersistentVolume is a handy abstraction because we can keep the `server` IP and the `path` there. But a PersistentVolumeClaim gets *any* PV with sufficient size, preventing `path` reuse.

Can set `volumeName` in a PVC `spec` block (see https://github.com/kubernetes/kubernetes/pull/7529) but it makes no difference.

Can a PVC be bound to a specific PV?

I&#39;m playing with Bootstrap 4 and I can&#39;t find a solution to add responsiveness to cards while in a `div` with `class=&quot;card-columns&quot;` (this class applies a Masonry-like effect to the cards inside the div having this class).

In Bootstrap 3 it was *easy* to style and make &quot;cards&quot; responsive since it was possible to apply something like `class=&quot;col-md-3 col-sm-6 col-xs-12&quot;` to a div containing `thumbnail`, `caption`, etc.

How to have the same effect while using cards in Bootstrap 4?

Here is the HTML:

```html
&lt;body&gt;

&lt;div class=&quot;container-fluid&quot;&gt;
    &lt;div class=&quot;row&quot;&gt;

        &lt;div class=&quot;col-md-4 hidden-sm-down&quot; id=&quot;map_container&quot;&gt;
            &lt;p&gt;here we put the map&lt;/p&gt;
        &lt;/div&gt;

        &lt;div class=&quot;col-md-8 col-sm-12 right_box&quot;&gt;

            &lt;div class=&quot;row&quot;&gt;

                // here there&#39;s code for navbar

            &lt;/div&gt;&lt;!-- row --&gt;

            &lt;div class=row&quot;&gt;
                &lt;div class=&quot;card-columns&quot;&gt;
                    &lt;?php
                    // Create and check connection
                    
                    if ($result-&gt;num_rows &gt; 0) {

                        // output card design
                        while($row = $result-&gt;fetch_assoc()) {

                            echo &#39;&lt;div class=&quot;card&quot;&gt;
                                    &lt;img class=&quot;card-img-top&quot; src=&quot;dance&#39; . $row[&quot;id&quot;] . &#39;.jpg&quot; alt=&quot;&#39; . $row[&quot;name&quot;] . &#39;&quot;&gt;
                                    &lt;div class=&quot;card-block&quot;&gt;
                                        &lt;h4 class=&quot;card-title&quot;&gt;&#39; . $row[&quot;name&quot;] . &#39;&lt;/h4&gt;
                                        &lt;p class=&quot;card-text&quot;&gt;Text. Card content.&lt;/p&gt;
                                    &lt;/div&gt;
                                    &lt;div class=&quot;card-footer text-muted&quot;&gt;
                                        &lt;ul class=&quot;list-inline&quot;&gt;
                                            &lt;li&gt;&lt;i class=&quot;fa fa-user&quot;&gt;&lt;/i&gt;&lt;/li&gt;
                                            &lt;li&gt;14&lt;/li&gt;
                                        &lt;/ul&gt;
                                    &lt;/div&gt;
                                  &lt;/div&gt;&lt;!-- card --&gt;&#39;;
                        }
                    } else {
                        echo &quot;0 results&quot;;
                    }

                    $conn-&gt;close();
                    ?&gt;
                &lt;/div&gt;&lt;!-- container card-columns --&gt;
            &lt;/div&gt;&lt;!-- row --&gt;
        &lt;/div&gt;&lt;!-- col-md-8 right_box --&gt;
    &lt;/div&gt;&lt;!-- row --&gt;
&lt;/div&gt;&lt;!-- container-fluid --&gt;
&lt;/body&gt;
```

And here is the CSS I&#39;ve used:

```css
#map_container {
background-image: url(map.png);
height: 100vh;
}

.right_box {
-webkit-box-shadow: -2px 0px 2px 0px rgba(0,0,0,0.75);
-moz-box-shadow: -2px 0px 2px 0px rgba(0,0,0,0.75);
box-shadow: -2px 0px 2px 0px rgba(0,0,0,0.75);
}

.card {
border-radius: 0 !important;
border: 0 none;
-webkit-box-shadow: 0px 2px 5px 0px rgba(0,0,0,0.5);
-moz-box-shadow: 0px 2px 5px 0px rgba(0,0,0,0.5);
box-shadow: 0px 2px 5px 0px rgba(0,0,0,0.5);
margin-left: 1px;
margin-right: 1px;
}

.card-img-top {
width: 100%;
border-radius: 0 !important;
}

.card-columns {
padding-top: 15px;
}
```

Given below are two images to make my situation clearer:

[Large screen][1]

[Smaller screen][2]

I&#39;d like cards to stack up vertically on smaller screens.

Thanks for your suggestions!

Bootstrap 4 - Responsive cards in card-columns

In MonoDevelop, when I type &quot;///&quot;, it auto-generates an xml-style comment like this:

    /// &lt;summary&gt;
	/// Describes the variable x
	/// &lt;/summary&gt;
    int x = 0;

Is there a way to get this behavior in Visual Studio Code?

The answers to questions like this: https://stackoverflow.com/questions/400135/c-sharp-listt-or-ilistt always seem to agree that returning an interface is better than returning a concrete implementation of a collection. But I&#39;m struggling with this. Instantiating an interface is impossible, so if your method is returning an interface, it&#39;s actually still returning a specific implementation. I was experimenting a bit with this by writing 2 small methods:

    public static IList&lt;int&gt; ExposeArrayIList()
    {
        return new[] { 1, 2, 3 };
    }

    public static IList&lt;int&gt; ExposeListIList()
    {
        return new List&lt;int&gt; { 1, 2, 3 };
    }

And use them in my test program:

    static void Main(string[] args)
    {
        IList&lt;int&gt; arrayIList = ExposeArrayIList();
        IList&lt;int&gt; listIList = ExposeListIList();
        
        //Will give a runtime error
        arrayIList.Add(10);
        //Runs perfectly
        listIList.Add(10);
    }

In both cases when I try to add a new value, my compiler gives me no errors, but obviously the method which exposes my array as an `IList&lt;T&gt;` gives a runtime error when I try to add something to it. 
So people who don&#39;t know what&#39;s happening in my method, and have to add values to it, are forced to first copy my `IList` to a `List` to be able to add values without risking errors. Of course they can do a typecheck to see if they&#39;re dealing with a `List` or an `Array`, but if they don&#39;t do that, and they want to add items to the collection **they have no other choice to copy the `IList` to a `List`, even if it already is a `List`**. Should an array never be exposed as `IList`?

Another concern of mine is based upon the accepted answer of the [linked question][1] (emphasis mine):

&gt; If you are exposing your class through a library that others will use, **you generally want to expose it via interfaces rather than concrete implementations.** This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of your library won&#39;t need to update their code since the interface doesn&#39;t change.

&gt;If you are just using it internally, you may not care so much, and using List&lt;T&gt; may be ok.

Imagine someone actually used my `IList&lt;T&gt;` they got from my `ExposeListIlist()` method just like that to add/remove values. Everything works fine. But now like the answer suggests, because returning an interface is more flexible I return an array instead of a List (no problem on my side!), then they&#39;re in for a treat...

TLDR: 

1) Exposing an interface causes unnecessary casts? Does that not matter?

2) Sometimes if users of the library don&#39;t use a cast, their code can break when you change your method, even though the method remains perfectly fine.

I am probably overthinking this, but I don&#39;t get the general consensus that returning an interface is to be preferred over returning an implementation.

Is returning IList&lt;T&gt; worse than returning T[] or List&lt;T&gt;?

I have the following view model

    public class ProjectVM
    {
        ....
        [Display(Name = &quot;Category&quot;)]
        [Required(ErrorMessage = &quot;Please select a category&quot;)]
        public int CategoryID { get; set; }
        public IEnumerable&lt;SelectListItem&gt; CategoryList { get; set; }
        ....
    }

and the following controller method to create a new Project and assign a `Category`

    public ActionResult Create()
    {
        ProjectVM model = new ProjectVM
        {
            CategoryList = new SelectList(db.Categories, &quot;ID&quot;, &quot;Name&quot;)
        }
        return View(model);
    }

    public ActionResult Create(ProjectVM model)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }
        // Save and redirect
    }

and in the view

    @model ProjectVM
    ....
    @using (Html.BeginForm())
    {
        ....
        @Html.LabelFor(m =&gt; m.CategoryID)
        @Html.DropDownListFor(m =&gt; m.CategoryID, Model.CategoryList, &quot;-Please select-&quot;)
        @Html.ValidationMessageFor(m =&gt; m.CategoryID)
        ....
        &lt;input type=&quot;submit&quot; value=&quot;Create&quot; /&gt;
    }

The view displays correctly but when submitting the form, I get the following error message

&gt;InvalidOperationException: The ViewData item that has the key &#39;CategoryID&#39; is of type &#39;System.Int32&#39; but must be of type &#39;IEnumerable&amp;lt;SelectListItem&amp;gt;&#39;.

The same error occurs using the `@Html.DropDownList()` method, and if I pass the SelectList using a `ViewBag` or `ViewData`.

The ViewData item that has the key &#39;XXX&#39; is of type &#39;System.Int32&#39; but must be of type &#39;IEnumerable&lt;SelectListItem&gt;&#39;

Ok, so basically I have a bunch of tasks (10) and I want to start them all at the same time and wait for them to complete. When completed I want to execute other tasks. I read a bunch of resources about this but I can&#39;t get it right for my particular case...

Here is what I currently have (code has been simplified):

    public async Task RunTasks()
    {
        var tasks = new List&lt;Task&gt;
        {
            new Task(async () =&gt; await DoWork()),
            //and so on with the other 9 similar tasks
        }
    
    
        Parallel.ForEach(tasks, task =&gt;
        {
            task.Start();
        });
    
        Task.WhenAll(tasks).ContinueWith(done =&gt;
        {
            //Run the other tasks
        });
    }
    
    //This function perform some I/O operations
    public async Task DoWork()
    {
        var results = await GetDataFromDatabaseAsync();
        foreach (var result in results)
        {
            await ReadFromNetwork(result.Url);
        }
    }

So my problem is that when I&#39;m waiting for tasks to complete with the `WhenAll` call, it tells me that all tasks are over even though none of them are completed. I tried adding `Console.WriteLine` in my `foreach` and when I have entered the continuation task, data keeps coming in from my previous `Task`s that aren&#39;t really finished.

What am I doing wrong here?

I&#39;m using [Automapper][1] in a project and I need to dynamically valorize a field of my destination object.

In my configuration I have something similar:

	cfg.CreateMap&lt;Message, MessageDto&gt;()
		// ...
		.ForMember(dest =&gt; dest.Timestamp, opt =&gt; opt.MapFrom(src =&gt; src.SentTime.AddMinutes(someValue)))
		//...
		;

The `someValue` in the configuration code is a parameter that I need to pass at runtime to the mapper and is not a field of the source object.

Is there a way to achieve this? Something like this:

    Mapper.Map&lt;MessageDto&gt;(msg, someValue));

I have installed Visual Studio 2015 Professional Edition, and my computer specs are Intel i7-3770 CPU 3.40&amp;nbsp;GHz, 8 GB RAM, and Windows 7 Enterprise 64-bit.

I want to upgrade my project to .NET 4.6 which is written in Visual studio 2005 .NET 2.0, but I have a serious problem about speed. After I open my project (huge project) in Visual Studio 2015 it is going crazy. Building, debugging, opening menus are too slow. Sometimes I got &quot;not responding&quot; message. Is it about Windows&amp;nbsp;7 or can you give me any advice about my speed problem?
