If you use Web API on top of ASP.NET they would ultimately both operate on the same underlying ASP.NET route table - however as correctly pointed out, from the user perspective you call two different methods to register route.

Routing was designed like this so that when hosting outside of ASP.NET, Web API wouldn&#39;t have to rely on System.Web. 

Bear in mind that Web API is not sitting on top of MVC, Web Forms, or, for that matter ASP.NET at all. It can be hosted within web context (ASP.NET) but can also be self hosted (Console, WPF etc) or even hosted in memory (without port use, useful for i.e. lightweight end-to-end testing).

`MapRoute` is meant for &quot;normal&quot; ASP.NET MVC controllers whereas `MapHttpRoute` is meant for Web API controllers.

I have two div elements. Each of them have 450px width and height. How do I check if the first div is overlapping the second div?

I&#39;ve tried to use javascript hittest, but it&#39;s a little bit complicated. Since I&#39;m trying to find out how it actually work, I would like to get started with a simpler code.

I found out that I can use **.getClientRects** to get the boundary of an element, but I&#39;m not exactly sure how to compare boundaries.

Please advise me!

What does the `cv::normalize(_src, dst, 0, 255, NORM_MINMAX, CV_8UC1);` do in OpenCV?

I went through  the documentation and was unable to understand what `alpha`, `beta`, `NORM_MINMAX` and `CV_8UC1` actually do. I am aware alpha sets the lower and beta the higher bound. `CV_8UC1` stands for an 8-bit unsigned single channel. But what exactly these arguments do to the picture is what I am unable to comprehend.

Why using &quot;MapRoute&quot; for &quot;Default&quot; routing, while using &quot;MapHttpRoute&quot; for &quot;DefaultApi&quot; routing?

      routeTemplate: &quot;api/{controller}/{action}&quot;

    routes.MapRoute(

It is unclear to me how the compiler will automatically know to compile for 64-bit when it needs to. How does it know when it can confidently target 32-bit?

I am mainly curious about how the compiler knows which architecture to target when compiling. Does it analyze the code and make a decision based on what it finds?

I am using visual studio 2010 and was wondering if there is a way to automatically remove all the namespaces that aren&#39;t being used at the the top of the page e.g.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Xml.Linq;

 in the above example System.Collections.Generic is not being used is there a way to know that without trial and error.

I&#39;m trying to wrap my head around the TPL, the new `async` / `await` features in C# 5, and the mysteries of `TaskCompletionSource`.

One thing that isn&#39;t clear to me is when to use `SetResult`, `SetException`, and `SetCancel` versus `TrySetResult`, `TrySetException` and `TrySetCancel`.

This is what MSDN has to say:

&gt; This operation will return false if the Task&lt;TResult&gt; is already in
&gt; one of the three final states: RanToCompletion, Faulted, or Canceled.
&gt; 
&gt; This method also returns false if the underlying Task&lt;TResult&gt; has
&gt; already been disposed.

Ok, I get that, but it doesn&#39;t really offer any guidance on when or why to use one over the other.  

So, what&#39;s the deal?

We&#39;re using OpenWeb js libraries on the frontend, and they have a need for the .NET middle tier to send them a specific HTTP header status code when certain types of errors occur. I tried to achieve that by doing this:

    public ActionResult TestError(string id) // id = error code
    {
        Request.Headers.Add(&quot;Status Code&quot;, id);
        Response.AddHeader(&quot;Status Code&quot;, id);
        var error = new Error();
        error.ErrorID = 123;
        error.Level = 2;
        error.Message = &quot;You broke the Internet!&quot;;

        return Json(error, JsonRequestBehavior.AllowGet);
    }

It kind of halfway worked. See screenshot:
![http status code](http://zerogravpro.com/temp/pic.png)

Notice I achieved the Status Code of 400 in the Response Header, but I really need the 400 in the Request Header. Instead, I get &quot;200 OK&quot;. How can I achieve this?

My URL structure for making the call is simple: /Main/TestError/400

I am trying out ASP.NET Bundling with ASP.NET MVC 4 application. The situation is that I want to make a CDN style service, which has JS and CSS files to which you can address from other sites with this type address: http://www.mycdn.com/scripts/plugin/js, which bundles and minifies all included .js files.

My bundle config for one file looks like this:

    bundles.Add(new ScriptBundle(&quot;~/Scripts/plugin/pluginjs&quot;).Include(&quot;~/Scripts/plugin/jquery.plugin.js&quot;));

However, when I do this, the bundles are not getting updated even after I change the original js files. I keep on getting 304 Not Modified, when I refresh my browser, and the content of the minified file is not updated. How can I make bundles update, because it is useless to have bundles with old content? I tried out every way, but could not figure out a solution.

Thanks in advance!

I have a Web Application project in VS 2012 and when I use the web publishing tool it builds successfully but doesn&#39;t copy any files to the publish target (File System in this case).

If I look at the build output I can see everything gets copied over to obj\Release\Package\PackageTmp\ correctly but then all I see in the build output is this:

&gt; 4&gt;Done building project &quot;{Project}.csproj&quot;.  
&gt; 4&gt;Deleting existing files...  
&gt; 4&gt;Publishing folder /...  
&gt; 4&gt; ========== Build: 3 succeeded, 0 failed, 1 up-to-date, 0 skipped ==========  
&gt; ========== Publish: 1 succeeded, 0 failed, 0 skipped ==========

Even though it says the publish succeeded there are not files in the target directory for the publish.

I have seen this in multiple projects and sometimes it seems like the Solution/Platform configurations cause this problem but I haven&#39;t been able to pinpoint an exact cause for this.

Has anyone else seen this happening or have an idea on how to get this working correctly?

**UPDATE:**

I may have found a workaround for this.  I just had this happen again and I was messing around with the publish settings.  Once I changed the selected Configuration on the Settings tab away to another configuration and then back to the one I wanted to use all my files started publishing again.  Hopefully this works on other projects in the future. 


**UPDATE 2:**

I posted a bug on Microsoft Connect and heard back from a developer on the VS Web Developer team.  He said they have fixed this issue in their internal builds and will releasing an update to the publish tool soon that will fix this problem.

**UPDATE 3:**

This has been recently fixed with Visual Studio 2012 Update 2

I have a table called Products which obviously contains products.
However, I need to create related products. So what I&#39;ve done is create a junction table called product_related which has two PKs. ProductID from Products table and RelatedID also from Products table.

I already use EF and have set up everything on other tables. How should I add this properly in order to create a relationship with products as such:
`product.Products.Add(product object here)`. Of course here `product` represent a product object that I&#39;ve fetched from the db using `db.Products.FirstOr...`.

How should I do this properly ? A many to many to the same table?

Thanks.

Using Visual Studio 2012, on a Razor view page, in the JavaScript section, I am getting what I think is a battle between Razor syntax vs JavaScript syntax. In particular, the trailing semicolon in the script section is flagged by intellisense and a compiler warning (not error) is delivered:

&gt; &#39;Warning 13 Syntax error&#39;.

If I remove it, then I get a statement termination recommendation ([ReSharper][1] in this case, but just good practice).

    &lt;script type=&quot;text/javascript&quot;&gt;
        $().ready(function(){
            var customer = @Html.Raw(ViewBag.CustomerJSON);  // &lt;- Razor (I think) doesn&#39;t like this semicolon
        });
    &lt;/script&gt;

Is this a bug in Razor? If so, is there a way I can rewrite this to avoid this issue?

Running Microsoft Server 2012 RC using Oracle&#39;s free VirtualBox Application.  Used a Bridged Network adapter type in the VirtualBox settings.  Installed AD and DNS, IIS.  Under the IIS  options, Management Tools, clicked the box for Management Services.  This allowed me to use the &quot;Web Deploy&quot; feature in Visual Studio 2012 RC.  On the guest OS, I run Windows 7 Ultimate.

I was able to successfully deploy the MVC 4 Application to IIS Default Web Site, but it wasn&#39;t displaying.  Instead, the default IIS home page was.  I disabled the default home page and refreshing the page displayed a 403 page.  I tried typing in one of the Views and a 404 page displayed.

I&#39;m using the default template generated by Asp.net Web Api. I&#39;m working with the Get() Part:

            // GET api/values
        public IEnumerable&lt;string&gt; Get()
        {
            return new string[] { &quot;value1&quot;, &quot;value2&quot; };
        }

For some reason the i thought the only thing you had to do to access to query string was just to create an input string variable. So i created one more function (the only change i made) to the default controller generated:

            public IEnumerable&lt;string&gt; Get(string queryString)
        {
            return new string[] { &quot;value3&quot;, &quot;value4&quot; };
        }


I put a break point in both methods but even if i add a query string it always goes to the function with no parameters. So if i go to `http://mybaseurl/api/values?foo=f`
 it still is going to Get() instead of get(string queryString). Does it not work the way i thought? I know i can access the query string in the Get() function using `Request.RequestUri.ParseQueryString();` but i prefer to have it separated like this if possible.

            Stream file = new MemoryStream();
            Stream result = _service.GetMyForm(id, dir, file);
            if (result == null)
            {
                return Request.CreateResponse(HttpStatusCode.NotFound);
            }
            result.Position = 0;
            HttpResponseMessage response = new HttpResponseMessage();
            response.StatusCode = HttpStatusCode.OK;
            response.Content = new StreamContent(result);
            return response;
        }
        catch (IOException)
        {
            return Request.CreateResponse(HttpStatusCode.InternalServerError);
        }
    }

Everything is working perfect except that default downloading file name is its id so user might have to type his/her own file name at save as dialog each time. Is there any way to set a default file name in the code above?

How to set downloading file name in ASP.NET Web API

I have a web application (hosted in IIS) that talks to a Windows service. The Windows service is using the ASP.Net MVC Web API (self-hosted), and so can be communicated with over http using JSON. The web application is configured to do impersonation, the idea being that the user who makes the request to the web application should be the user that the web application uses to make the request to the service. The structure looks like this:

![][1]

&lt;sub&gt;(The user highlighted in red is the user being referred to in the examples below.)&lt;/sub&gt;

----

The web application makes requests to the Windows service using an [`HttpClient`][2]:

    var httpClient = new HttpClient(new HttpClientHandler() 
                          {
                              UseDefaultCredentials = true
                          });
    httpClient.GetStringAsync(&quot;http://localhost/some/endpoint/&quot;);

This makes the request to the Windows service, but does not pass the credentials over correctly (the service reports the user as `IIS APPPOOL\ASP.NET 4.0`). **This is not what I want to happen**.

If I change the above code to use a [`WebClient`][3] instead, the credentials of the user are passed correctly:

    WebClient c = new WebClient
                       {
                           UseDefaultCredentials = true
                       };
    c.DownloadStringAsync(new Uri(&quot;http://localhost/some/endpoint/&quot;));

With the above code, the service reports the user as the user who made the request to the web application.

**What am I doing wrong with the `HttpClient` implementation that is causing it to not pass the credentials correctly** (or is it a bug with the `HttpClient`)?

&lt;sub&gt;The reason I want to use the `HttpClient` is that it has an async API that works well with `Task`s, whereas the `WebClient`&#39;s asyc API needs to be handled with events.&lt;/sub&gt;

Several months ago, Microsoft decided to change up the HttpResponseMessage class. Before, you could simply pass a data type into the constructor, and then return the message with that data, but not anymore.

Now, you need to use the Content property to set the content of the message. The problem is that it is of type HttpContent, and I can&#39;t seem to find a way to convert a string, for example, to HttpContent.

Does anyone know how to deal with this issue?

I have an ApiController and I want to use email addresses as the ID parameter for requests:

    // GET api/employees/email@address.com
    public CompactEmployee Get(string id) {
       var email = id;
       return GetEmployeeByEmail(email);
    }

However, I cannot get this to work (returns **404**):

`http://localhost:1080/api/employees/employee@company.com`

The following all work:
    
* `http://localhost:1080/api/employees/employee@company`
* `http://localhost:1080/api/employees/employee@company.`
* `http://localhost:1080/api/employees?id=employee@company.com`

I have set `relaxedUrlToFileSystemMapping=&quot;true&quot;` in my web.config as [detailed by Phil Haack][1].

I would very much love the full email address to work, but any time the period is followed by any other character, the request returns a 404. Any help would be greatly appreciated!

## Solution ##
Due to a lack of other options, I&#39;ve headed in the direction Maggie suggested and used the answer from [this question][2] to create a rewrite rule to automatically append a trailing slash when I need an email in the URL.

    &lt;system.webServer&gt;
      ....   
      &lt;rewrite&gt;
        &lt;rules&gt;
          &lt;rule name=&quot;Add trailing slash&quot; stopProcessing=&quot;true&quot;&gt;
            &lt;match url=&quot;^(api/employees/.*\.[a-z]{2,4})$&quot; /&gt;
            &lt;action type=&quot;Rewrite&quot; url=&quot;{R:1}/&quot; /&gt;
          &lt;/rule&gt;
        &lt;/rules&gt;
      &lt;/rewrite&gt;
    &lt;/system.webServer&gt;

        }
    }

Unfortunately, when trying to navigate to that URL I get this page:

    &lt;Error&gt;
        &lt;Message&gt;
            No HTTP resource was found that matches the request URI &#39;http://localhost:52684/User/f2acc4d0-2e03-4d72-99b6-9b9b85bd661a/VerifyEmail?secretKey=e9bf3924-681c-4afc-a8b0-3fd58eba93fe&#39;.
        &lt;/Message&gt;
        &lt;MessageDetail&gt;
            No type was found that matches the controller named &#39;User&#39;.
        &lt;/MessageDetail&gt;
    &lt;/Error&gt;

and here is my UserController:

    public class UserController : Controller
    {

        // GET	    /User/{id}/VerifyEmail
        [HttpGet]
        public ActionResult VerifyEmail(string id, string secretKey)
        {
            try
            {
                User user = UsersBL.Instance.Verify(id, secretKey);
                //logger.Debug(String.Format(&quot;User %s just signed-in in by email.&quot;,
                    user.DebugDescription()));
            }
            catch (Exception e)
            {
                throw new Exception(&quot;Failed&quot;, e);
            }
            return View();
        }
    }

Please tell me what am I doing wrong?


No type was found that matches the controller named &#39;User&#39;

I want to be able to request static `.html` files which are located in the `~/Views` folder.
According to the documentation, the routing system checks to see if a URL matches a disk file before evaluating the application&#39;s routes.

But when I request the file a `404` error arises. 

My file is located in ~/Views folder.
The URL is: `http://[localhost]/Views/HtmlPage1.html`

What have I missed?


How do you request static .html files under the ~/Views folder in ASP.NET MVC?
