asp.net mvc @Html.CheckBoxFor dynamic

using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Web;

 namespace CorePartners_Site2.Models
 {
public class CareerForm
     {
    //....
    public List<CheckBoxes> EmploymentType { get; set; } 
      }
 }

 public class CheckBoxes
 {
     public string Text { get; set; }
     public bool Checked { get; set; }
 }
and added at my form
@Html.CheckBoxFor(model => model.EmploymentType, new { id = "employmentType_1" })
@Html.CheckBoxFor(model => model.EmploymentType, new { id = "employmentType_2" })
@Html.CheckBoxFor(model => model.EmploymentType, new { id = "employmentType_3" })
CheckBoxFor takes a bool, you're passing a List<CheckBoxes> to it. You'd need to do:
@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "employmentType_" + i })
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.DisplayFor(m => m.EmploymentType[i].Text)
}
Notice I've added a HiddenFor for the Text property too, otherwise you'd lose that when you posted the form, so you wouldn't know which items you'd checked.
Edit, as shown in your comments, your EmploymentType list is null when the view is served. You'll need to populate that too, by doing this in your action method:
public ActionResult YourActionMethod()
{
    CareerForm model = new CareerForm();

    model.EmploymentType = new List<CheckBox>
    {
        new Checkbox { Text = "Fulltime" },
        new Checkbox { Text = "Partly" },
        new Checkbox { Text = "Contract" }
    };

    return View(model);
}

Set the Reference Path (C#)

To set a reference path

  1. In Solution Explorer, select the project.
  2. On the Project menu, click <Project Name> Properties.
  3. Click Reference Paths.
  4. In the Folder text box, specify the path of the folder that contains assemblies. To browse to the folder, click the ellipsis (…).
  5. Click Add Folder.

To overwrite a reference path

  1. In Solution Explorer, select the project.
  2. On the Project menu, click <Project Name> Properties.
  3. Click Reference Paths.
  4. In the Reference Path box, select the path to overwrite.
  5. In the Folder text box, specify the path of the folder that contains assemblies. To browse to the path, click the ellipsis (…).
  6. Click Update. The path selected in the Reference Path box is overwritten with the path specified in the Folder text box.

To remove a reference path

  1. In Solution Explorer, select the project.
  2. On the Project menu, click <Project Name> Properties.
  3. Click Reference Paths.
  4. In the Reference Path box, select the path to remove.
  5. Click Remove.

auto focus text box

$(".inputs").keyup(function () {
    if (this.value.length == this.maxLength) {
      var $next = $(this).next('.inputs');
      if ($next.length)
          $(this).next('.inputs').focus();
      else
          $(this).blur();
    }
});
<input class="inputs" type="text" maxlength="4" />
<input class="inputs" type="text" maxlength="4" />
<input class="inputs" type="text" maxlength="4" />
<input class="inputs" type="text" maxlength="4" />
<input class="inputs" type="text" maxlength="4" />
<input class="inputs" type="text" maxlength="4" />

The breakpoint will not currently be hit. No symbols have been loaded for this document.

Start debugging, as soon as you've arrived at a breakpoint or used Debug > Break All, use Debug > Windows > Modules. You'll see a list of all the assemblies that are loaded into the process. Locate the one you want to get debug info for. Right-click it and select Symbol Load Information. You'll get a dialog that lists all the directories where it looked for the .pdb file for the assembly. Verify that list against the actual .pdb location. Make sure it doesn't find an old one.
In normal projects, the assembly and its .pdb file should always have been copied by the IDE into the same folder as your .exe. The bin\Debug folder of your project. Make sure you remove one from the GAC if you've been playing with it.

A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll in C#.net application..What is a first chance exception?

"First chance exception messages most often do not mean there is a problem in the code." 
When an application is being debugged, the debugger gets notified whenever an exception is encountered  At this point, the application is suspended and the debugger decides how to handle the exception. The first pass through this mechanism is called a “first chance” exception. Depending on the debugger’s configuration, it will either resume the application and pass the exception on or it will leave the application suspended and enter debug mode. If the application handles the exception, it continues to run normally.

In Visual Studio, you may see a message in the output window that looks like this:

A first chance exception of type ‘System.ApplicationException’ occurred in myapp.exe

In Visual Studio 2005 Beta2, you will see this message anytime a first chance exception is encountered in your application’s code.  If you are using Visual Studio .NET 2003, this message is shown if you have configured the debugger to stop when the specific exception type is thrown.

If the application does not handle the exception, the debugger is re-notified. This is known as a “second chance” exception. The debugger again suspends the application and determines how to handle this exception. Typically, debuggers are configured to stop on second chance (unhandled) exceptions and debug mode is entered, allowing you to debug. 

Does a first chance exception mean there is a problem in my code?First chance exception messages most often do not mean there is a problem in the code. For applications / components which handle exceptions gracefully, first chance exception messages let the developer know that an exceptional situation was encountered and was handled.

For code without exception handling, the debugger will receive a second chance exception notification and will stop with a unhandled exception.

bool System.Boolean
byte System.Byte
sbyte  System.SByte
char System.Char
decimal System.Decimal
double System.Double
float System.Single
int System.Int32
uint System.UInt32
long System.Int64
ulong System.UInt64
object System.Object
short System.Int16
ushort System.UInt16
string System.String

Folder Permissions on Windows Azure Web Sites

What you can do is change permissions on a local instance of the application and then deploy it with Web Deploy. When you do that, Web Deploy will use the SetAcl operation to change permissions.
SetACL – Automate Permissions and Manage ACLs...
----------------------------------------------------------------------------------------------------------------------

Folder permissions cannot be set/customized. This means whatever location your app writes to should be under your site root.

Difference between single quotes and double quotes in Javascript

You'll want to use single quotes where you want double quotes to appear inside the string (e.g. for html attributes) without having to escape them, or vice versa. Other than that, there is no difference.
I wouldn't say there is a preferred method. You can use either. However, if you are using one form of quote in the string, you might want to use the other as the literal.
alert('Say "Hello"');

alert("Say 'Hello'");
