My goal is to join two tables by specific IDs using the following within an async command.

result = (from Alpha in db.TABLE1 join Beta in db.TABLE2 on Alpha.
          where Alpha.COLUMN.Equals(query) 
          select new 

I am getting an async issue at the select level.

My question is how do you use LINQ lambda join commands within an async controller?

I attempted to use ActionResult instead but the other controllers I am using are ASYNC and I would like to continue to use the ASYNC if at all possible.

In test project, I add folder App_GlobalResources. Within that folder I add LocalizedText.resx,, and LocalizedText.en.resx. And fill them with with values, eg. Text: Text in specific language. In cshtml, to get them, I use @Resources.LocalizedText.Text.

Problem is - I cannot get it to work properly.. I am switching languages is multiple browsers, all give me the same. If I don't add LocalizedText.en.resx, it allways takes value out of LocalizedText.resx, but with LocalizedText.en.resx, it allways takes values out of it.

Am I missing something? Why doesnt it work properly?

I'm trying to rewrite an old mvc1 application as a vNext app in vs2014. Application authenticates against the company's active directory. Here's a bit of a background to help clarify where my confusion is coming from.

I wrote one app in mvc4 which authenticates the following way: 1. Vs template had account login post action with isValid method 2. I wrote my membership provider and registered it through web.config 3. When I run application isValid is now calling my override that does authentication

Now I'm in vNext and here's what I see 1. Same account and login method except there's some signinmanager and user manager passed into it. I'm yet to see where it's coming from exactly. I suspect it's through startup.cs 2. I see that isValid is replaced with something like Passwordsigninasync which I think I need to override to login the user.

Here's my question how do I make Passwordsigninasync authenticate to our AD? I can go solo and ignore the framework to make it work but I'm sure there's an easy way to do it and I'm just missing some understanding of how plumbing works in vNext. Appreciate any help in the right direction.

I have this property in my model :

[DisplayName("Birth Date")]
public Nullable<System.DateTime> dtnasc { get; set; }

use on view the htmlhelper

 @Html.LabelFor(_ => _.dtnasc)

and receive this error : Nullable object must have a value.

When value of property dtnasc is null, how can we get DisplayName Metadata?

I have an ASP.NET MVC website and a subdirectory "/dir/" under it which is also configured as an ASP.NET application.

I want the http://website/dir/ URL to route to a parent controller if some condition is met, or simply ignore it and "pass over" to the subdir-application if not. How do I do this?

PS. I cannot use RouteExistingFiles = true because both apps have some aspx/ashx/html files that need to work.

I am new to C#. In php setting session and get session data in model class I use something like this

class Users_model extends CI_Model
    function auth(){
        //get session value of username
        //set session data 

How would I achieve the same in my UsersModel.cs class in C# using razor MVC structure since I require the session data in the model to use in a query?

I need to get fresh specific hastag tweets in c# or c# or mvc

I have a Razor view in which I want to render the result of another action. So what I tried doing is this

@Html.Action("Index", "Home", new { area = "Portal" })

However this doesn't seem to render anything on the page. But when I check which URL is rendered by the Url.Action with the same parameters it's giving me the proper URL.

@Url.Action("Index", "Home", new { area = "Portal" }) // this shows /Portal/Blog/Index
@Html.Action("Index", "Home", new { area = "Portal" }) // this doesn't show anything

And if I go in my browser to /Portal/Blog/Index I can see content I'm trying to load just fine. I've even tried removing all of the code from HomeController so the action is simply

public ActionResult Index()
    // also tried returning this.PartialView() but it makes no difference
    return this.View();

and the Index.cshtml is just

    Layout = null;

I have a problem with setting default route in my MVC project. My global.asax doesn't have Routes.MapRoute, it just has the code bellow:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Routing;

namespace razor
    // Note: For instructions on enabling IIS6 or IIS7 classic mode, 
    // visit
    public class MvcApplication : System.Web.HttpApplication
        protected void Application_Start()


I am trying to render the FirstName entered by the user as a label in the View. I have tried...

@Html.DisplayFor(c => c.FirstName)
@Html.LabelFor(c => c.FirstName)
@Html.DisplayNameFor(c => c.FirstName)

What is the best way? Seems simple, I am obviously missing something? Using the second one, I am getting the variable name, not the value.

Controller Code:

namespace TestProject.Controllers
    public class ContactsController : Controller
        public ActionResult Index()
            Contact contact = new Contact();

            return View(contact);

View Code:

@model TestProject.Models.Contact

    ViewBag.Title = "ContactSuccess";
    Layout = "~/Views/Shared/_Layout.cshtml";

<h2>Contact Has Been Successfully Added</h2>
<div class="imgContainer">
<img src="~/Content/Images/checkmark" />

I am using ODataLib 6.6.0 and Microsoft.AspNet.OData 5.2.1 Nuget packages.

I have the following code which creates a custom serializer to add a custom annotation to a paged OData feed. The code compiles and is called correctly, all the way through the point of adding the custom instance annotation.

namespace WebApiTest.App_Start
    using Microsoft.OData.Core;
    using System.Collections.Generic;
    using System.Web.Http;
    using System.Web.OData.Formatter;
    using System.Web.OData.Formatter.Deserialization;
    using System.Web.OData.Formatter.Serialization;
    using WebApiTest.Controllers;

    public class FormatterConfiguration
        public static void Register(HttpConfiguration config)
            var formatters = ODataMediaTypeFormatters.Create(
                new CustomODataSerializerProvider(),
                new DefaultODataDeserializerProvider());
            config.Formatters.InsertRange(0, formatters);

    public class CustomODataSerializerProvider : DefaultODataSerializerProvider
        private readonly CustomODataFeedSerializer _feedSerializer;

        public CustomODataSerializerProvider()
            _feedSerializer = new CustomODataFeedSerializer(this);

        public override ODataEdmTypeSerializer GetEdmTypeSerializer(Microsoft.OData.Edm.IEdmTypeReference edmType)
            var serializer = base.GetEdmTypeSerializer(edmType);
            var feedSerializer = serializer as ODataFeedSerializer;
            if (feedSerializer != null)
                return _feedSerializer;
            return serializer;

    public class CustomODataFeedSerializer : ODataFeedSerializer
        public CustomODataFeedSerializer(ODataSerializerProvider serializerProvider)
            : base(serializerProvider)

        public override Microsoft.OData.Core.ODataFeed CreateODataFeed(System.Collections.IEnumerable feedInstance, Microsoft.OData.Edm.IEdmCollectionTypeReference feedType, ODataSerializerContext writeContext)
            ODataFeed feed = base.CreateODataFeed(feedInstance, feedType, writeContext);
            var result = feedInstance as IPageResultCustom;
            if (result != null)
                var value = new ODataComplexValue();
                var properties = new List<ODataProperty>();
                properties.Add(new ODataProperty() { Name = "CustomProperty", Value = result.CustomProperty });
                value.Properties = properties;
                feed.InstanceAnnotations.Add(new ODataInstanceAnnotation("org.CustomComplexValue", value));
            return feed;

I issue a request to a feed including the HTTP headers Prefer: odata.include-annotations="*" and Content-Type=application/json in the request. Yet, I get no annotations in the response.

Tracing through the OData framework code, the internal property Func<string,bool> Microsoft.OData.Core.MessageWriterSettings.ShouldInludeAnnotations is never set when creating the ODataMessageWriters and therefore, the ODataJsonLightValueSerializer.ShouldSkipAnnotation(string name) method call always returns true.

It seems like a bug in the framework. Am I missing something in my configuration or request?

Edit Aug 7, 2014

The issue appears to be related to the bug

A workaround was suggested that involved creating a custom ODataMediaTypeFormatter. However, ODataMediaTypeFormatters.Create is not generic and recreating it involves too many dependencies that are internally scoped. This workaround is a daunting task at a minimum. It appears that the realistic limit of extensibility on ODataMediaTypeFormatter is confined to implementing custom serializers and/or deserializers.

I have created a web api in mvc5. And now through the separate mvc application in same platform i want to register an account and login through it. How will i be able to register as well as login through my mvc application? The api provides the token in json after passing these values in localhost:35237/Token through post method


and in return i get the json value with access-token, token_type, expires_in, userName, .issued, .expires.

access_token: "tR4lyDuXiohwmywmqyACV2DOG188M5vPKVBVyq9ffQjOwuSuzYolV8BK554FcUIu8v0O1h08rL_hZO91x-1Y8N6r4GbqSrqnfQzdOhPbXKCDVzt9z9ro2mDXwOzg0-AkcVlE4AAblHmUNExPQjNLmtiEtK0TYPW_RK6Bjf5QNTy4NTT22fKZJAbFnLojsZnWh1ptLDtTVan-XSQH7uEbW6HLceEuiJSAtFfqTFlkiT6eYA7IuGswmHoxeOQ2ED9Aw_Q7fdY23cylFJDxsC5ZLK7kkweVyTYEqagLl0Q3xSSsE2n2HY17YSy0l3dIX4RLJ9axy28a8LS6rJs33Aag9bTVs2V8C55xwqbPU49r8Ro5Hnq3C5mbeoqikv9mj41FBHRG1H9a-tAZ24bP0L95CsCUlUDSFuHRaaouN4JN3Jo"

I am new to using the Grid.MVC feature. After looking at some of the examples i really like the grid and I was wondering how i could implement a solution similar to the example on the documentation page. I have the grid created and am trying to add the details to the right of the grid as shown but I not sure how to implement it. Here is the exmaple I am trying to accomplish with MVC and Razor.

Here is what I have in my view:

@using GridMvc.Html
@using GridMvc.Sorting
@model IEnumerable<EmployeeManagement.Models.EmployeeMaster>

    ViewBag.Title = "Index";
    <meta name="viewport" content="width=device-width" />
    <link href="@Url.Content("~/Content/Gridmvc.css")" rel="stylesheet" />
    <link href="@Url.Content("~/Content/bootstrap.min.css")" rel="stylesheet" />
    <script src="@Url.Content("~/Scripts/jquery-1.9.0.min.js")"></script>
    <script src="@Url.Content("~/Scripts/gridmvc.min.js")"></script>
        pageGrids.employeeGrid.onRowSelect(function (e) {
            $.post("/Manage/GetEmployee?id=" + e.row.EmployeeNumber, function (data) {
                if (data.Status <= 0) {


<div id="grid" style="float: left">
    @Html.Grid(Model).Columns(columns =>

    columns.Add(o => o.LastName)
            .Titled("Last Name")

    columns.Add(o => o.FirstName)
            .Titled("First Name")

    columns.Add(o => o.Initials)

    columns.Add(o => o.Branch)

    columns.Add(o => o.StatusFlag)

    columns.Add(o => o.EmployeeNumber)
            .Titled("Employee NO")

        .RenderValueAs(d =>
                @Html.ActionLink("Edit", "Edit")
}).SetRowCssClasses(item => (bool)item.StatusFlag ? "success" : "danger").Sortable().Filterable().WithMultipleFilters().Named("employeeGrid")

<div id="details" style="float:left">
    <div id="employee-content">
        Click on an employee to get their detailed record.


Here is GetEmployee Method looks like:

    public EmployeeMaster GetEmployee(int id)
        var e = EmployeeDb.EmployeeMasters.FirstOrDefault(x => x.EmployeeNumber == id);
        return e;

I am using Entity Framework 6.1 in webform project. When I try to add new object into projects, I am getting Ambiguous match found exception. I am using database first approach. I do not any manipulation in created models. I have read some questions about that problem. General cause is same named properties and navigation in class. I did not found any same named property.

Can you tell me what i missed?

Thank you

I use the MachineKey.Protect() method to encrypt the id passed as a query string in my MVC application.

Here's the code I use to encrypt/decrypt:

public static string Encrypt(this string expression)
    if (string.IsNullOrEmpty(expression))
        return string.Empty;

    byte[] stream = Encoding.Unicode.GetBytes(expression);
    byte[] encodedValue = MachineKey.Protect(stream);            
    return HttpServerUtility.UrlTokenEncode(encodedValue);            

public static string Decrypt(this string expression)
    if (string.IsNullOrEmpty(expression))
        return string.Empty;

    byte[] stream = HttpServerUtility.UrlTokenDecode(expression);
    byte[] decodedValue = MachineKey.Unprotect(stream);
    return Encoding.Unicode.GetString(decodedValue);

And, here is the MachineKey element in my web.config file:

    <machineKey validationKey="xxx" decryptionKey="xxx" validation="SHA1" decryption="AES" />

The problem is the encrypted id is not persistent. Every time I call the method, I get a new encrypted expression. How do I make it persistent?

I have a website hosted on a Windows Server 2008, using IIS 7.5.


Around three times a day, my website is goes down. When I try to open or browse it, I get a 404 Not Found.

Temporary Fix:

I've found that I can make it work if I edit my web.config file and upload it to server again with FTP.

<compilation debug="false" targetFramework="4.0" />

It works if I toggle the value of the debug attribute of the compilation element. This brings the site back online again for five to six hours.

I'm not sure whether this is an issue with the code, the server, or the client.

Has anyone experienced any similar behavior? Is there a more permanent solution than having to change that attribute every few hours?

Problem is that I am getting an error:

Uncaught TypeError: undefined is not a function

at this line:


and I have no idea why.

Any ideas please?

I know this issue has arisen many times on Stack Overflow. I've looked at them, but believe this to be unique:

  • I'm not using .Single() or .SingleOrDefault() in any LINQ expressions
  • I checked my models for duplicates, like "Id" and "ID", there are none
  • This happens onload of any Kendo UI MVC grids, on any table, on any page in my website that has such a grid, and we have several different pages, each with their own grids

Just some history, we just changed some foreign keys to Guids from IDs (ints) in order to point them at different tables in the database than they are currently in the code. Models were updated, accordingly. We also added a view for the Kendo grid to be pointed at, and this was changed in the view. But even grids that have nothing to do with the original or new SQL view/C# models seem to have been affected. Now, during this phase:

public OurDatabase(bool enableLazyLoading=true)
    : base("name=OurDBContext")
    ((IObjectContextAdapter)this).ObjectContext.ContextOptions.ProxyCreationEnabled = enableLazyLoading;
    ((IObjectContextAdapter)this).ObjectContext.ContextOptions.LazyLoadingEnabled = enableLazyLoading;

It keeps giving the error "Sequence contains more than one matching element". It will highlight on that middle line with that error.

Can something changing in the database cause this? Code that once worked, and hasn't been changed since that time, now does not, and this is very confusing.

I have 2 different layouts in my project that based on the view that is called, I will tell the view which layout to use. I'm having an issue where my first layout is rendered (my landing page), I render a certain set of scripts/styles. Once I want to render my 2nd layout, the browser is holding on to all the styles/scripts from my previous layout. Is there anyway to decouple those scripts/styles when changing layouts?

I have a web application being developped on Windows 8.1, .net 4.5.1, IIS 8.5 (under Integrated AppPool), Visual Studio 2013 Over the default template that includes Identity, Owin, etc. and locally works fine.

then I Uploaded it to a windows server 2008 & IIS 7.5 (Integrated Pipeline) Host and I get:

This operation requires IIS integrated pipeline mode.

Exception Details: System.PlatformNotSupportedException: This operation requires IIS integrated pipeline mode.

Stack Trace:

I have searched a lot and unable to find anything except for directing the reader to change the pipeline from classic mode to integrated mode that which I already did with no luck..

What can I do to fix the problem? Does "Microsoft.Owin.Host.SystemWeb" not like IIS 7.5, or server 2008 or me :) ?
