Start URL has to be a fully qualified URL and is not really used that often.  It&#39;s meant for testing web services by opening a page that will call into the service, but isn&#39;t part of the application itself.

If you&#39;re just looking to start on a certain page of your application, which it sounds like you want, then use the &quot;Specific Page&quot; field, and enter your relative URL.

[Here&#39;s the doc page on project start options.][1]


  [1]: http://msdn.microsoft.com/en-us/library/aa983445.aspx

Use **Start Page** \ **Specific Page** -- **NOT START URL** -- and specify your URL *without* a slash.

That oughta do it for you.

I was looking for a similar solution for VS2015. If anyone is reading this and you just want to run/debug via Visual Studio 2015 without having to attach to process and you&#39;re happy to run through Local IIS instead of Cassini or IIS Express, you can set a config like this:

I have just removed the files with .user extension in my web project and the solution map and the problem is solved now. Try to close your solution in Visual Studio and take a backup of files you &quot;remove&quot;first.

I have a datatable with 4 columns A, B, C and D such that a particular combination of values for column A, B and C is unique in the datatable.

**Objective:** To find the value of column D, for a given combination of values for column A, B and C.

I guess looping over the set of data rows should do it. Is there a way to use Datatable.Select() to accomplish this? To be more specific - can I have multiple conditions in the select filter i.e. a logical AND operator connecting conditions for each of the columns A, B and C.


Datatable select with multiple conditions

I&#39;m trying to install couchapp, which uses easy_install - and is quite explicit in stating a particular version of easy_install/setuptools is needed: 0.6c6. I seem to have easy_install already on my Mac, but there&#39;s no command-line arguments to check the version. Instead of just installing a new version over the top, I&#39;d like to see whether it&#39;s necessary first.

So: Any pointers on how I can see what version of setuptools/easy_install I have installed on my machine?

I&#39;m not a Python developer, so I&#39;m assuming this is a simple question. However, I&#39;ve not found anything via Google or here on SOF.

Visual Studio ASP.NET MVC project: setting the start URL

Consider an ASP.NET MVC 2 project with VS 2010. The goal is to set the 'start URL' on run/debug using VS's built-in Cassini web server.

I&#39;m working with some WebForms/MVC-agnostic tools, and I need to get an instance of `HttpContext` given a reference to an `HttpContextBase` object. I can&#39;t use `HttpContext.Current` because I need this to work asynchronously as well (`HttpContext.Current` returns `null` during an asynchronous request). I&#39;m aware of `HttpContextWrapper`, but goes the wrong way.

How do I get an HttpContext object from HttpContextBase in ASP.NET MVC 1?

how do I throw a 404 or FileNotFound exception/result from my action and let IIS use my customErrors config section to show the 404 page?

I&#39;ve defined my customErrors like so

    &lt;customErrors mode=&quot;On&quot; defaultRedirect=&quot;/trouble&quot;&gt;
      &lt;error statusCode=&quot;404&quot; redirect=&quot;/notfound&quot; /&gt;
    &lt;/customErrors&gt;



My first attempt at an actionResult that tries to add this doesnt work.

    public class NotFoundResult : ActionResult {
        public NotFoundResult() {
          
        }

        public override void ExecuteResult(ControllerContext context) {
            context.HttpContext.Response.TrySkipIisCustomErrors = false;
            context.HttpContext.Response.StatusCode = 404;
        }
    }

But this just shows a blank page and not my /not-found page

:(

Is there a built-in way of getting the full URL of an action?

I am looking for something like `GetFullUrl(&quot;Action&quot;, &quot;Controller&quot;)` that would return something like `http://www.fred.com/Controller/Action`.

The reason I am looking for this is to avoid hardcoding URLs in automated emails that are generated so that the URLs can always be generated relative to the current location of the site.


Getting full URL of action in ASP.NET MVC

Something pretty weird is happening with my app:

I have the following property in my ViewModel:

    public int? StakeholderId { get; set; }

It gets rendered in a *partial* view as follows:

    &lt;%= Html.Hidden(&quot;StakeholderId&quot;, Model.StakeholderId) %&gt;

The form is submitted, and the relevant controller action generates an id and updates the model, before returning the same view with the updated model 

The problem I&#39;m experiencing is that the hidden field does not have anything in its &quot;value&quot; attribute rendered the second time even though StakeholderId now has a value. 

If I just output the value on its own, it shows up on the page, so I&#39;ve got it to render the value by doing this:

    &lt;input type=&quot;hidden&quot; id=&quot;StakeholderId&quot; name=&quot;stakeholderId&quot; value=&quot;&lt;%: Model.StakeholderId %&gt;&quot; /&gt;

But it&#39;s pretty strange that the helper doesn&#39;t pick up the updated value?

(I&#39;m using jQuery to submit forms and render the action results into divs, but I&#39;ve checked and the html I get back is already wrong before jQuery does anything with it, so I don&#39;t think that has much to do with anything)


**UPDATE**

I&#39;ve since discovered that I can also clear the relevant ModelState key before my controller action returns the partial view.

ASP.NET MVC: Hidden field value does not get rendered using HtmlHelper.Hidden

I need to generate some URLs in a model in ASP.NET MVC. I&#39;d like to call something like UrlHelper.Action() which uses the routes to generate the URL. I don&#39;t mind filling the usual blanks, like the hostname, scheme and so on.

Is there any method I can call for that? Is there a way to construct an UrlHelper?

Visual Studio 2008 lets me declare a command and attach it to the post-build event for a project. Like a lot of developers, I use it regularly to xcopy files to the application output directory.

I am working on a project where I need to xcopy files from two different places to two different destinations, all within a single project. In other words, I need to invoke two different xcopy commands from the same post-build event. It looks like the post-build event will only take a single command, and that if I need to invoke multiple commands, I will have to put the commands in a *.bat file and call that from the post-build event.

Is that correct, or is there a simpler way to invoke two commands from the post-build event? Thanks in advance for your help.

Visual Studio: Multiple post-build commands?

I get this error when I try to load a VS 2008 project from TFS source control:

&gt; The project file has been moved, renamed or is not on your computer

After I click OK the project says &quot;unavailable&quot;.
What is the problem? How do I resolve this? I never had this problem before. Some blogs said to delete the .suo file but I can&#39;t locate the .suo file. I deleted the entire project on my local computer so that the next time it opens it will create a new one, but I still get same error.


The project file has been moved renamed or is not on your computer

I have a simple WinForms solution in VS 2010. Whenever I build it, output file (bin\debug\app.exe) ends up locked, and subsequent builds fail with a message like 
`&quot;The process cannot access the file &#39;bin\Debug\app.exe&#39; because it is being used by another process.&quot;`
The only way to build the project is to restart VS after every build, which is *very* awkward.

I have found this old blog post http://blogs.geekdojo.net/brian/archive/2006/02/17/VS2005FileLocking.aspx - it seems that the problem is really old. Does anyone know what is happening here, or at least some workaround?

**Update**

I don&#39;t actually *run* the file. Locking happens after build, not after debug (i.e. start VS - build - build - fail!)
And I tried turning antivirus off. It doesn&#39;t help.

**Update 2**

Process Explorer shows devenv.exe having loaded the file (in DLLs, not in Handles). It seems like some glitch during build prevented the unloading, but the (first) build completes without any messages other then &quot;1 succeeded, o failed&quot;/

Visual Studio locks output file on build

I have a Visual Studio 2008 C#/.NET 3.5 project with a post build task to ZIP the contents. However I&#39;m finding that I&#39;m also getting the referenced assemblies&#39; .pdb (debug) and .xml (documentation) files in my output directory (and ZIP). 

For example, if MyProject.csproj references YourAssembly.dll and there are YourAssembly.xml and YourAssembly.pdb files in the same directory as the DLL they will show up in my output directory (and ZIP).

I can exclude *.pdb when ZIP&#39;ing but I cannot blanket exclude the *.xml files as I have deployment files with the same extension.

Is there a way to prevent the project from copying referenced assembly PDB and XML files?

I&#39;ve got a Visual Studio C# project which is under version control (SVN).
I&#39;ve always commited and updated the project without any problems. But a couple of hours ago Visual Studio throws the following error when I try to launch/rebuild the project:

&gt; Files has invalid value &quot;&lt;&lt;&lt;&lt;&lt;&lt;&lt;
&gt; .mine&quot;. Illegal characters in path.

I don&#39;t know how to fix this problem. What should I do?

I&#39;ve been using Beta 2 for a while now and it&#39;s been driving me nuts that I have to punt to cmd.exe when running the Visual&amp;nbsp;Studio&amp;nbsp;2010 Command Prompt. I used to have a nice *vsvars2008.ps1* script for Visual Studio 2008. Is there a *vsvars2010.ps1* script or something similar?

I am upgrading lots of C# projects from vs.net 2008 to vs.net 2010 rc. I notice that the upgrade creates a BootstrapperPackage section inside the *.csproj file (include Microsoft.NET.Framework.3.5 and 3.5sp1). I wonder what the BootstrapperPackage does and do I need them?

I get this error when compiling a C# application. Looks like a trivial error, but I can&#39;t get around it.
  
My setup is Windows 7 64 bit. Visual-Studio 2010 C# express B2Rel.
  
I added a reference to System.Web.dll located at `C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0`, but it has a yellow exclamation symbol and I still get the above error. I also have the `using System.Web` declaration.

What am I doing wrong?

___
**Update:** After getting the prompt answer pointing me at the root cause, I searched a bit in Google to where it states that System.Web.dll is for the full framework. I did not find such a reference.  
For newbies like me, [**this**][1] blog summarizes the difference between the frameworks (client and full) nicely. I could not find a spot that says whether a certain Dll is supported in the client framework or not. I guess the exclamation mark in Visual Studio should be the first signal...

This DLL is added by default in Visual Studio 2010 projects. What is this new assembly used for? It does not seem to contain much after looking at it using Reflector and Google does not seem to have much to say about it either.

In VS2010 they added to all projects a virtual directory called &quot;External Dependencies&quot;:

![alt text][1]

It really bothers me especially because if there is a normal folder named &quot;Apple&quot; and one named &quot;Deep&quot; it will be in between the two, and also the information it gives is, in my opinion, completely useless.

VS2010: how to remove/hide the &quot;External Dependencies&quot; folder in Solution Explorer

I&#39;m at wit&#39;s end. Visual Studio is *typically* painfully slow to debug or just plain load (&quot;start without debugging&quot;) my ASP.NET MVC sites. Not always: at first, the projects will load nice and fast, but once they load slow, they&#39;ll always load slowly after that. I could be waiting 1-2 minutes or more.

**My setup:**

I&#39;m using [Visual Studio 2012 Express][1], currently, but I&#39;ve had the same problem in Visual Studio 2010 Express as well. My solution is stored on a network drive; specifically, it&#39;s My Documents redirected to a network drive, if it matters. (It shouldn&#39;t. There are times where my site loads very fast under this setup.)

I load in Internet&amp;nbsp; Explorer 9 usually, but the same problem happens in Firefox.

This can happen in any ASP.NET MVC project I work on, and it seems to revolve around having DisplayTemplates, which all my ASP.NET MVC projects do. And it&#39;s all C# and Razor if that mattered.

### Symptoms:

The system will load my symbols *hundreds* of times. Basically, the following, but there are at least 300 such rows, each with ever-so-slightly different DLL files for the same CSHTMLs:

    &#39;iisexpress.exe&#39; (Managed (v4.0.30319)): Loaded &#39;C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\b63f8236\6775085d\App_Web_contact.cshtml.22013bb9.xighmhow.dll&#39;, Symbols loaded.
    &#39;iisexpress.exe&#39; (Managed (v4.0.30319)): Loaded &#39;C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\b63f8236\6775085d\App_Web_contact.cshtml.22013bb9.cv5hktkf.dll&#39;, Symbols loaded.
    &#39;iisexpress.exe&#39; (Managed (v4.0.30319)): Loaded &#39;C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\b63f8236\6775085d\App_Web_statuscode.cshtml.22013bb9.1o77hs8i.dll&#39;, Symbols loaded.
    &#39;iisexpress.exe&#39; (Managed (v4.0.30319)): Loaded &#39;C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\b63f8236\6775085d\App_Web_statuscode.cshtml.22013bb9.jja-77mw.dll&#39;, Symbols loaded.
    &#39;iisexpress.exe&#39; (Managed (v4.0.30319)): Loaded &#39;C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\b63f8236\6775085d\App_Web_location.cshtml.22013bb9.l_e9ev_s.dll&#39;, Symbols loaded.
    &#39;iisexpress.exe&#39; (Managed (v4.0.30319)): Loaded &#39;C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\b63f8236\6775085d\App_Web_location.cshtml.22013bb9.b4n59gom.dll&#39;, Symbols loaded.

In the above, I&#39;ve got three DisplayTemplates: &quot;Contact&quot;, &quot;Location&quot;, and &quot;StatusCode&quot;. It appears that IIS is loading symbols twice for each time the display template gets called. Thus, if I&#39;m displaying a table of 100 entries that call all three of these display templates, it&#39;s 600 separate symbols loaded.

This isn&#39;t a fast operation either. The log files that IIS generates take about 200&amp;nbsp; ms for each symbol to load. Thus, super-long delays.

**What I&#39;ve Tried:**

 - Debug or Release version, it doesn&#39;t matter.
 - Putting my project on a full IIS implementation on a web server runs it super fast with no problems.
 - Cassini, IIS&amp;nbsp; Express 7.5, and IIS&amp;nbsp; Express 8.0 all have the problem.
 - **Delete All Breakpoints does nothing.**
 - *Clean Solution*, or deleting the .suo also do nothing.
 - If I repair IIS&amp;nbsp; Express/ delete the `My Docs\IISExpress` folder, or repair/reinstall Visual Studio → the issue MAY go away, but only for a while before it comes right back.

Any advice at all is appreciated.

To answer more questions, yes my machine definitely has horsepower. The infuriating thing is that the same project, with NOTHING altered, can sometimes load very quickly, typically after I repair IIS&amp;nbsp; Express and delete the `My Docs\IISExpress` folder. Eventually, &quot;something&quot; happens and it&#39;s down to 2 minutes to load again. What I&#39;m working on is not a complicated project. No external libraries or dependencies and my VS.NET has no add-ons whatsoever.

Of note, this machine has Symantec Endpoint Protection, which has a history of causing havoc. But disabling it outright (it&#39;s good to be an administrator) did not fix the problem.

I have a theory at this point. I&#39;m thinking this is all because I&#39;m working off a redirected folder off a network share. While the debugger was going through its hundreds of &quot;loaded symbols&quot; lines, I paused to see what it was doing. It was in my code, loading the DisplayTemplate I had. Stepping into the template output this:

It looks like Visual Studio is recompiling my display template **every time** it&#39;s called, which is again, hundreds of times. My theory is that Visual Studio compiles the file, saves it to the network share, then somehow stamps a new time on it, and Visual Studio then thinks the file has changed. Thus, Visual Studio recompiles it yet again. Only a theory though; I really have no clue.

For one, apparently, I have offline files (this is a desktop computer in an office; I couldn&#39;t care less). I&#39;m going to disable, reboot, and retry tomorrow.

Plus, moving my project, as is, to the local C: fixes it. It loads very quickly. But this is not ideal in a work environment. I lose Previous Versions, my code isn&#39;t backed up at all unless I manually copy it, and it&#39;s no longer shared with anyone.

I can make do with copying it back and forth from C to the network share if it comes to it. It&#39;s much more annoying to wait two minutes for every page to load.
