My bundles were registered as paths which corresponded to an actual folder on the solution, e.g. `~/Content/forum`.

This works fine when bundling is turned off (the bundle is included correctly!), but not when bundling is enabled.

The solution is to change the registered name of the bundle to not be the same as anything that exists in the file system.

In my case bundle was specified as a directory `@Scripts.Render(&quot;~/scripts&quot;)` so IIS did not know how to serve the actual js file, I changed the bundle name to represent a javascript file `@Scripts.Render(&quot;~/scripts.js&quot;)` and that fixed it. The same was true for my style bundle.

The problem is the naming convention your bundle name should be 

    (&quot;bundles/css&quot;) 
This solved my problem.


Currently I use `foreach` loop to return a list of `object` properties. 

     class X
     {
         List&lt;X&gt; Z = GetXlist();
         List&lt;String&gt; r = new List&lt;String&gt;();
        
         foreach (var z in Z)
         {
             r.Add(z.A);
         }
        
         return r;
    }

Is there a way that I can shorten this so that I don&#39;t have to write the `foreach` loop?

When I run my android app from eclipse, I get this error. 

    Unexpected exception &#39;Cannot run program &quot;/home/antz/Development/adt-bundle-linux/sdk/platform-tools/adb&quot;: error=2 No such file or directory&#39; while attempting to get adb version from /home/antz/Development/adt-bundle-linux/sdk/platform-tools/adb

COPY PASTE FROM Eclipse Error

    [2012-11-26 13:43:08 - adb] Unexpected exception &#39;Cannot run program &quot;/home/antz/Development/adt-bundle-linux/sdk/platform-tools/adb&quot;: error=2, No such file or directory&#39; while attempting to get adb version from &#39;/home/antz/Development/adt-bundle-linux/sdk/platform-tools/adb&#39;

However my adb is exactly in the location where it says it&#39;s not. 

What is wrong and how do I fix this?

I cd into the directory where adb is (`/home/antz/Development/adt-bundle-linux/sdk/platform-tools/`) and I typed in adb and it says

    antz@antz-90X3A:~/Development/adt-bundle-linux/sdk/platform-tools$ ls  
    aapt  aidl  dexdump  fastboot  llvm-rs-cc  renderscript  
    adb   api   dx       lib       NOTICE.txt  source.properties  
    antz@antz-90X3A:~/Development/adt-bundle-linux/sdk/platform-tools$ adb  
    bash: /home/antz/Development/adt-bundle-linux/sdk/platform-tools/adb: No such file or directory

adb is green which means its an executable, correct?

for example, dx is also green and when I typed in dx into the command prompt, it works... whats wrong with adb?

When bundling/minification is enabled, some of my bundles seem to have an invalid URL in the browser (ending with a /), and IIS gives a 403 forbidden error, as if trying to list a folder&#39;s contents.

There&#39;s no difference in the way my bundles are set up - they are not .min.css, access permissions are correct etc.

I&#39;m designing a class that I wish to make readonly after a main thread is done configuring it, i.e. &quot;freeze&quot; it. Eric Lippert calls this [popsicle][1] immutability. After it is frozen, it can be accessed by multiple threads concurrently for reading.

My question is how to write this in a thread safe way that is *realistically* efficient, i.e. without trying to be unnecessarily *clever*.

**Attempt 1:**

    public class Foobar
    {
       private Boolean _isFrozen;
       
       public void Freeze() { _isFrozen = true; }
    
       // Only intended to be called by main thread, so checks if class is frozen. If it is the operation is invalid.
       public void WriteValue(Object val)
       {
          if (_isFrozen)
             throw new InvalidOperationException();
             
          // write ...
       }
       
       public Object ReadSomething()
       {
          return it;
       }
    }

Eric Lippert seems to suggest this would be OK in [this][2] post.
I know writes have release semantics, but as far as I understand this only pertains to *ordering*, and it doesn&#39;t necessarily mean that all threads will see the value immediately after the write. Can anyone confirm this? This would mean this solution is not thread safe (this may not be the only reason of course).

**Attempt 2:**

The above, but using `Interlocked.Exchange` to ensure the value is actually published:

    public class Foobar
    {
       private Int32 _isFrozen;
       
       public void Freeze() { Interlocked.Exchange(ref _isFrozen, 1); }
    
       public void WriteValue(Object val)
       {
          if (_isFrozen == 1)
             throw new InvalidOperationException();
             
          // write ...
       }
    }

Advantage here would be that we ensure the value is published without suffering the overhead on every read. If none of the reads are moved before the write to _isFrozen as the Interlocked method uses a full memory barrier I would guess this is thread safe. However, who knows what the compiler will do (and according to section 3.10 of the C# spec that seems like quite a lot), so I don&#39;t know if this is threadsafe.

**Attempt 3:**

Also do the read using `Interlocked`.

    public class Foobar
    {
       private Int32 _isFrozen;
       
       public void Freeze() { Interlocked.Exchange(ref _isFrozen, 1); }
    
       public void WriteValue(Object val)
       {
          if (Interlocked.CompareExchange(ref _isFrozen, 0, 0) == 1)
             throw new InvalidOperationException();
             
          // write ...
       }
    }

Definitely thread safe, but it seems a little wasteful to have to do the compare exchange for every read. I know this overhead is probably minimal, but I&#39;m looking for a *reasonably* efficient method (although perhaps this is it).

**Attempt 4:**

Using `volatile`:

    public class Foobar
    {
       private volatile Boolean _isFrozen;
       
       public void Freeze() { _isFrozen = true; }
    
       public void WriteValue(Object val)
       {
          if (_isFrozen)
             throw new InvalidOperationException();
             
          // write ...
       }
    }

But Joe Duffy declared &quot;[sayonara volatile][3]&quot;, so I won&#39;t consider this a solution.

**Attempt 5:**

Lock everything, seems a bit overkill:

    public class Foobar
    {
       private readonly Object _syncRoot = new Object();
       private Boolean _isFrozen;
       
       public void Freeze() { lock(_syncRoot) _isFrozen = true; }
    
       public void WriteValue(Object val)
       {
          lock(_syncRoot) // as above we could include an attempt that reads *without* this lock
             if (_isFrozen)
                throw new InvalidOperationException();
             
          // write ...
       }
    }

Also seems definitely thread safe, but has more overhead than using the Interlocked approach above, so I would favour attempt 3 over this one.

And then I can come up with at least some more (I&#39;m sure there are many more):

**Attempt 6:** use `Thread.VolatileWrite` and `Thread.VolatileRead`, but these are supposedly a little on the heavy side.

**Attempt 7:** use `Thread.MemoryBarrier`, seems a little too *internal*.

**Attempt 8:** create an immutable copy - don&#39;t want to do this

Summarising:

- which attempt would you use and why (or how would you do it if entirely different)? (i.e. what is the best way for publishing a value once that is then read concurrently, while being reasonably efficient without being overly &quot;clever&quot;?)
- does .NET&#39;s memory model &quot;release&quot; semantics of writes imply that all other threads see updates (cache coherency etc.)? I generally don&#39;t want to think too much about this, but it&#39;s nice to have an understanding.

EDIT:

Perhaps my question wasn&#39;t clear, but I am looking in particular for reasons as to why the above attempts are good or bad. Note that I am talking here about a scenario of one single writer that writes then freezes before any concurrent reads. I believe attempt 1 is OK but I&#39;d like to know exactly why (as I wonder if reads could be optimized away somehow, for example).
I care less about whether or not this is good design practice but more about the actual threading aspect of it.

Many thanks for the response the question received, but I have chosen to mark this as an answer myself because I feel that the answers given do not *quite* answer my question and I do not want to give the impression to anyone visiting the site that the marked answer is correct simply because it was automatically marked as such due to the bounty expiring.
Furthermore I do not think the answer with the highest number of votes was overwhelmingly voted for, not enough to mark it automatically as an answer.

I am still leaning to attempt #1 being correct, however, I would have liked some authoritative answers. I understand x86 has a strong model, but I don&#39;t want to (and shouldn&#39;t) code for a particular architecture, after all that&#39;s one of the nice things about .NET.

If you are in doubt about the answer, go for one of the locking approaches, perhaps with the optimizations shown here to avoid a lot of contention on the lock.

How to freeze a popsicle in .NET (make a class immutable)

I want to disable cascade deletes for a link table with entity framework code-first.  For example, if many users have many roles, and I try to delete a role, I want that delete to be blocked *unless* there are no users currently associated with that role.  I already remove the cascade delete convention in my `OnModelCreating`:

	protected override void OnModelCreating(DbModelBuilder modelBuilder) {
		...
		modelBuilder.Conventions.Remove&lt;OneToManyCascadeDeleteConvention&gt;();

And then I set up the user-role link table:

	modelBuilder.Entity&lt;User&gt;()
		.HasMany(usr =&gt; usr.Roles)
		.WithMany(role =&gt; role.Users)
		.Map(m =&gt; {
			m.ToTable(&quot;UsersRoles&quot;);
			m.MapLeftKey(&quot;UserId&quot;);
			m.MapRightKey(&quot;RoleId&quot;);
		});

Yet when EF creates the database, it creates a delete cascade for the foreign key relationships, eg.

	ALTER TABLE [dbo].[UsersRoles]  WITH CHECK ADD  CONSTRAINT [FK_dbo.UsersRoles_dbo.User_UserId] FOREIGN KEY([UserId])
	REFERENCES [dbo].[User] ([UserId])
	ON DELETE CASCADE
	GO
	
	ALTER TABLE [dbo].[UsersRoles]  WITH CHECK ADD  CONSTRAINT [FK_dbo.UsersRoles_dbo.Role_RoleId] FOREIGN KEY([RoleId])
	REFERENCES [dbo].[Role] ([RoleId])
	ON DELETE CASCADE
	GO

How can I stop EF generating this delete cascade?

I&#39;m wondering if there are any differences between `MemoryCache` and `HttpRuntime.Cache`, which one is preferred in ASP.NET MVC projects?

As far as I understand, both are thread safe, API is from first sight more or less the same, so is there any difference when to use which?

I want to show a ValidationSummary mcv3 with &quot;alert-error&quot; Bootstrap styling.

I&#39;m using a Razor view, and I show model errors with this code:

     @Html.ValidationSummary(true, &quot;Errors: &quot;)

 It generates HTML code like this:

    &lt;div class=&quot;validation-summary-errors&quot;&gt;
       &lt;span&gt;Errors:&lt;/span&gt;
       &lt;ul&gt;
          &lt;li&gt;Error 1&lt;/li&gt;
          &lt;li&gt;Error 2&lt;/li&gt;
          &lt;li&gt;Error 3&lt;/li&gt;
       &lt;/ul&gt;
    &lt;/div&gt;
                 

I tried with this too:

    @Html.ValidationSummary(true, &quot;Errors:&quot;, new { @class = &quot;alert alert-error&quot; })   


and it works ok, but without the close button (X)

It generates HTML code like this:

    &lt;div class=&quot;validation-summary-errors alert alert-error&quot;&gt;
       &lt;span&gt;Errors:&lt;/span&gt;
       &lt;ul&gt;
          &lt;li&gt;Error 1&lt;/li&gt;
          &lt;li&gt;Error 2&lt;/li&gt;
          &lt;li&gt;Error 3&lt;/li&gt;
       &lt;/ul&gt;
    &lt;/div&gt;

but Bootstrap alert should have this button into the div:

    &lt;button type=&quot;button&quot; class=&quot;close&quot; data-dismiss=&quot;alert&quot;&gt;&#215;&lt;/button&gt;

Can anyone help?

Show ValidationSummary MVC3 as &quot;alert-error&quot; Bootstrap

I want a custom error page shown for 500, 404 and 403. Here&#39;s what I have done:

1. Enabled custom errors in the web.config as follows:

        &lt;customErrors mode=&quot;On&quot; 
                      defaultRedirect=&quot;~/Views/Shared/Error.cshtml&quot;&gt;
      
            &lt;error statusCode=&quot;403&quot; 
                   redirect=&quot;~/Views/Shared/UnauthorizedAccess.cshtml&quot; /&gt;
      
            &lt;error statusCode=&quot;404&quot; 
                   redirect=&quot;~/Views/Shared/FileNotFound.cshtml&quot; /&gt;
    
        &lt;/customErrors&gt;

2. Registered `HandleErrorAttribute` as a global action filter in the `FilterConfig` class as follows:

        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new CustomHandleErrorAttribute());
            filters.Add(new AuthorizeAttribute());
        }

3. Created a custom error page for each of the above messages. The default one for 500 was already available out of the box.

4. Declared in each custom error page view that the model for the page is `System.Web.Mvc.HandleErrorInfo`

For 500, it shows the custom error page. For others, it doesn&#39;t.

Is there something I am missing?

It does look like this is not all there is to displaying custom errors as I read through the code in the `OnException` method of the `HandleErrorAttribute` class and it is handling only 500.

What do I have to do to handle other errors?

How to make custom error pages work in ASP.NET MVC 4

I have recently started playing around with ASP.net MVC (4), but I can&#39;t wrap my head around this one issue I&#39;m having. I&#39;m sure it&#39;s easy when you know it.

I&#39;m essentially trying to do the the following in my Index view:

1. List the current items in the database of type &quot;Note&quot; in the Index view (that&#39;s easy)
2. Creating new items in the same Index view (not so easy). 

So I figured I needed a partial view, and that I have created as following (_CreateNote.cshtml):

    @model QuickNotes.Models.Note
    @using (Html.BeginForm()) {
    @Html.ValidationSummary(true)

    &lt;fieldset&gt;
        &lt;legend&gt;Note&lt;/legend&gt;

        &lt;div class=&quot;editor-label&quot;&gt;
            @Html.LabelFor(model =&gt; model.Content)
        &lt;/div&gt;
        &lt;div class=&quot;editor-field&quot;&gt;
            @Html.EditorFor(model =&gt; model.Content)
            @Html.ValidationMessageFor(model =&gt; model.Content)
        &lt;/div&gt;
        &lt;p&gt;
            &lt;input type=&quot;submit&quot; value=&quot;Create&quot; /&gt;
        &lt;/p&gt;
    &lt;/fieldset&gt;
    }

In my original Index view (Index.cshtml) I&#39;m trying to render this partial view:

    @model IEnumerable&lt;QuickNotes.Models.Note&gt;
    
    
    @{
        ViewBag.Title = &quot;Personal notes&quot;;
    }
    
    &lt;h2&gt;Personal notes&lt;/h2&gt;
    
    &lt;p&gt;
        @Html.ActionLink(&quot;Create New&quot;, &quot;Create&quot;)
    &lt;/p&gt;
    
    &lt;table&gt;
        &lt;tr&gt;
            &lt;th&gt;
                @Html.DisplayNameFor(model =&gt; model.Content)
            &lt;/th&gt;
            &lt;th&gt;&lt;/th&gt;
        &lt;/tr&gt;
    
        @foreach (var item in Model) {
            &lt;tr&gt;
                &lt;td&gt;
                    @Html.DisplayFor(modelItem =&gt; item.Content)
                &lt;/td&gt;
                &lt;td&gt;
                    @Html.ActionLink(&quot;Edit&quot;, &quot;Edit&quot;, new { id=item.ID }) |
                    @Html.ActionLink(&quot;Details&quot;, &quot;Details&quot;, new { id=item.ID }) |
                    @Html.ActionLink(&quot;Delete&quot;, &quot;Delete&quot;, new { id=item.ID })
                &lt;/td&gt;
            &lt;/tr&gt;
        }
    &lt;/table&gt;
    
    &lt;div&gt;
        @Html.Partial(&quot;_CreateNote&quot;)
    &lt;/div&gt;

(using: @Html.Partial(&quot;_CreateNote&quot;))
However. This doesn&#39;t seem to work, as I get the following error message: 

    Line 35: 
    Line 36: &lt;div&gt;
    Line 37:     @Html.Partial(&quot;_CreateNote&quot;);
    Line 38: &lt;/div&gt;
    
    Source File: c:\Dropbox\Projects\workspace .NET MVC\QuickNotes\QuickNotes\Views\Notes\Index.cshtml    Line: 37 
    
    Stack Trace: 
    
    
    [InvalidOperationException: The model item passed into the dictionary is of type &#39;System.Data.Entity.DbSet`1[QuickNotes.Models.Note]&#39;, but this dictionary requires a model item of type &#39;QuickNotes.Models.Note&#39;.]
       System.Web.Mvc.ViewDataDictionary`1.SetModel(Object value) +405487

My NotesController looks like this:

    public ActionResult Index()
    {

        var model = _db.Notes;
        
        return View(model);
    }

    //
    // GET: /Notes/Create

    public ActionResult Create()
    {
        return View();
    }

    //
    // GET: /Notes/_CreateNote - Partial view
    public ViewResult _CreateNote()
    {
        return View(&quot;_CreateNote&quot;);
    }

I think it has to do with the fact that the Index view is using the model differently, as in @model IEnumerable, but no matter how I change it around, using RenderPartial, RenderAction, changing ActionResult to ViewResult etc, I can&#39;t get it to work.

Any tips would be greatly appreciated!
Please let me know if you need any more information. I&#39;d be happy to zip down the entire project if needed.

Using partial views in ASP.net MVC 4

I know this is a pretty basic question over here. 

But could you tell me ***all possible options*** available to,
  &lt;br/&gt;call a ***Control Action Method [generally any server side routine] from a Razor View*** and, 
  &lt;br/&gt;in what ***scenarios each are best applicable*** to be used in.

Thanks.

In this line:

    @Html.ActionLink(&quot;Reply&quot;, &quot;BlogReplyCommentAdd&quot;, &quot;Blog&quot;,
             new { blogPostId = blogPostId, replyblogPostmodel = Model,
             captchaValid = Model.AddNewComment.DisplayCaptcha })

I get the following runtime error on blogPostId:

&gt; The parameters dictionary contains a null entry for parameter
&gt; &#39;blogPostId&#39; of non-nullable type &#39;System.Int32&#39; for method
&gt; &#39;System.Web.Mvc.ActionResult BlogReplyCommentAdd(Int32,
&gt; Nop.Web.Models.Blogs.BlogPostModel, Boolean)&#39; in
&gt; &#39;Nop.Web.Controllers.BlogController&#39;. An optional parameter must be a
&gt; reference type, a nullable type, or be declared as an optional
&gt; parameter. Parameter name: parameters

I have already assign a value for this on top such as 

        @{         
            var blogPostId = Model.Id;          
         }

My Controller:

     public ActionResult BlogReplyCommentAdd(int blogPostId, BlogPostModel model, bool captchaValid)
        {}

Am I doing something wrong? Please give me an example.

I want to do this:

    string template = &quot;Hello @Model.Name! Welcome to Razor!&quot;;
    string result = Razor.Parse(template, new { Name = &quot;World&quot; });

And it appears that http://razorengine.codeplex.com is perfect, except it&#39;s a year old.

EDIT: Turns out that RazorEngine has moved to GitHub and had a commit a few months back: https://github.com/Antaris/RazorEngine

I noticed that Service Stack has some Razor self-hosting but while there&#39;s a long page here http://razor.servicestack.net there&#39;s no &quot;hello world you can totally do this from a console.&quot;

I&#39;m looking to create a Bootstrap styled textbox, specifically, based on the exact example below:

    &lt;input class=&quot;span3&quot; type=&quot;email&quot; required&gt;

Here&#39;s what I have so far:

    @Html.TextBox(&quot;CustomerEmail&quot;, null, new { @class = &quot;input-xlarge&quot;, type = &quot;email&quot;, required = &quot;required&quot; })

However, `required = &quot;required&quot;` clearly doesn&#39;t return just `required`.

So, my question is, is there any way I can force it to return required like in the first example above when using Html.Textbox?

In my Win 7 development machine, and in order to use SQL Express instance instead of the localDB installed by default. I unchecked &quot;Use IIS Express&quot; in my MVC 4 project properties page (Web tab), then I got the following error:

**ASP.NET 4.5 has not been registered on the Web server. You need to manually configure your Web server for ASP.NET 4.5 in order for your site to run correctly.**

I verified that ASP.NET is activated within the IIS features.

Please what could be done to resolve this?


ASP.NET 4.5 has not been registered on the Web server

I&#39;m looking for a command to run against the `MSBuild.exe` that just takes a MVC 4 project and publishes it to a given directory.

For example, 

    MSBuild &lt;solution&gt;/&lt;project&gt;.csproj -publish -output=c:/folder

This is obviously incorrect syntax. I&#39;m trying to simplify my question.

   [q]: https://stackoverflow.com/questions/3097489/how-to-publish-web-with-msbuild

[This question][q] talks of a build XML, but I&#39;m not trying to do anything with that much detail.

I&#39;m simply trying to do a deploy.

Further down in [that question][q], someone speaks of &quot;MSDeploy&quot;. I can look into that, but is it the only option? I do not have the ability to install web deploy on the server. In which case, all I really need to do is &quot;Publish&quot; and send the contents of the published project to a given directory on the server/file-system.

Does anyone have a one liner I can use?

Do I have to use MSDeploy?

Does MSDeploy require web deploy to be installed on the server?

Doesn&#39;t setting up web deploy on the server require setting up some ports, permissions, and installing some IIS add-ons?

I&#39;d love to just execute something simple.

Could not load file or assembly &#39;DotNetOpenAuth.Core

We are using MVC Bundling in our site, `CssRewriteUrlTransform` makes sure that the image urls work from the dynamic bundle css file. 

But this only works when not using a virtual directory, i.e 

`http://localhost/VirttualDir` does not work but `http://localhost/` does. This is because the `CssRewriteUrlTransform` tranform does not take the virtual folder into account when rewriting the url. So if a image real path is `localhost/vdir/content/img/foo.png` it will rewrite it to `localhost/content/img/foo.png` which is wrong 

CssRewriteUrlTransform with or without virtual directory

I have gulp task script as following,

    // loads various gulp modules
    var gulp = require(&#39;gulp&#39;);
    var concat = require(&#39;gulp-concat&#39;);
    var minifyCSS = require(&#39;gulp-minify-css&#39;);
    var autoprefixer = require(&#39;gulp-autoprefixer&#39;);
    var rename = require(&#39;gulp-rename&#39;);
    
    // create task
    gulp.task(&#39;css&#39;, function(){
        gulp.src(&#39;src/css/**/*.css&#39;)
            .pipe(minifyCSS())
            .pipe(rename(&#39;style.min.css&#39;))
            .pipe(autoprefixer(&#39;last 2 version&#39;, &#39;safari 5&#39;, &#39;ie 8&#39;, &#39;ie 9&#39;))
            .pipe(gulp.dest(&#39;dist/css&#39;))
    });

How to minify all the css files from src/css to a single file as dist/css/style.min.css?
