Did you return a model to the view?

Remember I said you need to update the controller for the view, by creating the model and returning it to the view.

return View(model);

I don't know about the viewbag, I don't use them anymore.

Yes I am passing the model still it gives me error saying "Name model doesn't exist in current context" at the place where I am mentioning @model

Here is my View

@*@using MVCWithWebApiApp.Models

@model MVCWithWebApiApp.Models.User

@{
    ViewBag.Title = "Index";
}*@

<!DOCTYPE html>

            </td>
        </tr>

</body>
</html>

And my controller I have added this code still it doesn't help me.

public ActionResult CreateUser()
{
    User user = new User();
    user.UserId = 1;
    user.UserName = "Abdul";

    return View(user);
}

Yes I am doing it here is the code that I am doing, but still it gives me errors in all those places of @Url, @model and ViewBag all of them, I know you are not using ViewBag but I giving that information because the errors that maybe related anyways I am getting tired with ASP.Net MVC specially the ones that are given Microsoft that are like Html Helper classes etc.

I never faced difficulty in resolving errors in any other place.

public ActionResult Index()
{
    var dbContext = new MVCDBContext();

    List<User> listOfUsers;
    listOfUsers = dbContext.Users.ToList();

    return View(listOfUsers);
}

Thanks,

Oh your using angular. I thought you were using Razor and HTML Helpers. My Bad it was in your example in the first post.

How to use AngularJS in ASP.NET MVC and Entity Framework - Evangelism - Infragistics.com Blog[^]

With Angular, you make calls to JsonResults, which is like a webservice, only your calling the controller for just json data. Then the Angular takes the Json data and populates the fields. So modify that controller code to return JsonResult, get your data as a list and return it.

I don't know much difference in both buddy, just asking OK if I am using angular, in the browser should we call the action method or should we call the plain html file? I am confused which to use when?

There is an application with us named "MirrorTools" which was existing more than 7 years and we are not the developers (no clue on whether this application developed internally within organization or online product)

We have an Mirrortools.exe and MirrorTools.exe.config file.I am calling this Mirrortools by via an .bat file which carries the following code

@echo off
title TestRaw Refresh
MirrorTools --refresh --dtimeout=86400 A.xml BLog
MailSender --to=aaa@yahoo.com,bbb@yahoo.com --subject="[MirrorTools] TestRAWSubject Refresh USPLSVULM132" BLog
del BLog

and the config file contains following code...

<?xml version="1.0"?>
<configuration>
    <system.data>
        <DbProviderFactories>
          <remove invariant="Oracle.DataAccess.Client" />
            <add name="Oracle .NET Data Provider" description="Oracle .NET Data Provider" invariant="Oracle.DataAccess.Client" type="Oracle.DataAccess.Client.OracleClientFactory, Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342"/>
        </DbProviderFactories>
    </system.data>
</configuration>

While I am executing the bat file i am getting the following error

Unhandled exception : system.configuration.configurationerrorexception: Failed to find or load the registered .net framework data provider.

Overview
The purpose of the application is to allow end-users to quickly enter and manage a list of name/value pairs.
Although this test must be written without any other persons help, any standard reference material that is used during a normal programming cycle may be used (such as online help or books). No third party class libraries or code snippets may be used.
Create a Windows Forms application using a UI similar to the one shown below. The application code should be written in C# , unless you are specifically applying for a position that does not require C# skills or were given instructions to do otherwise.

Required Features:
Name/Value pairs are to be entered into the upper textbox. This textbox will be used by the end-user to quickly add Name/Value pairs to the list below.
When a Name/Value pair is about to be added to the list it must be validated to ensure proper syntax. If the syntax is incorrect then the Name/Value pair must not be added. The Name/Value pair entry format is shown below:
=
Where is the name portion of the pair, and is the value portion of the pair. Only valid Name/Value pairs can be added. Names and Values can contain only alpha-numeric characters. The equal-sign is used to delimit the pair, spaces before and/or after the equal-sign may be entered by the end user (and should be ignored.)
When the ‘Sort by Name’ button is pressed the list will be sorted ascending by Name.
When the ‘Sort by Value’ button is pressed the list will be sorted ascending by Value.
When the ‘Delete’ button is pressed all selected items in the listbox will be deleted.
When the ‘Save as XML’ button is pressed, all of the items in the listbox must be saved to an XML file.
When the ‘Exit’ button is pressed the program will close.

Create a Web Forms application using a user interface similar to the one shown below. However feel free to modify the layout to allow for better usability, if desired. 
All server-side code should be in C#

 
Required Features:
1.	Name/Value pairs are to be entered into the upper textbox. This textbox is used for adding and filtering Name/Value pairs.
2.	When the ‘Add’ button is pressed the Name/Value pair in the textbox is validated, and then if it passes validation it is added to the listbox below. The Name/Value pair entry format is shown below:
3.	<name> = <value>
4.	Where <name> is the name portion of the pair, and <value> is the value portion of the pair. Only valid Name/Value pairs can be added. Names and Values can contain only alpha-numeric characters. The equal-sign is used to delimit the pair, spaces before and/or after the equal-sign may be entered as padding at the end-users discretion. 
5.	When the ‘Sort by Name’ button is pressed the list will be sorted ascending by Name.
6.	When the ‘Sort by Value’ button is pressed the list will be sorted ascending by Value.
7.	When the ‘Delete’ button is pressed all selected items in the listbox will be deleted.
Optional Features 
The following features are a test option and may not be required, please refer to the job description to see if it is a requirement
1.	When the ‘Filter’ button is pressed, only the Name/Value pairs that match the filter criteria will be shown in the listbox. The search criteria will be taken from the textbox. 

Filters have the following format (and are similar to the Name/Value format): 

<type> = <value> 

Where <type> is either Name or Value, and <value> is a string used for matching against the given type.  
2.	When the ‘Clear Filter’ button is pressed all of the Name/Value pairs will be shown in the listbox.

Re: Well after the last 5 days, I feel unchained from the Microsoft ball now! MVC with Bower, NPM and Gulp and Docker

10-Jun-16 7:35

Well what an adventure after 5 days of trying to figure all this out. But after getting my project up and running, I now see the benefits as a whole, and it was well worth it. Many of the earlier questions I had about MVC have now been answered, such as what's up with the Razor, what is Webgrease and how to use it, and how do we minify our CSS and Script files.

So while we were watching Steve Ballmer try to buy the LA Clippers, the new CEO Satya Nadella has been working to let Microsoft developers have more fun creating apps, by unchaining us from the boiler plated project templates and letting us choose how we want to work.

My 5 day journey in the last week has exposed me to all sorts of new concepts that appear to be working great out there such as Node.js, but I digress, and will return back to the topic.

Bower:
So in case you didn't know, Bower is another way to download packages that can be automated. It's not a replacement for NuGet, which is still viable for server side packages, but the preferred way to download front end frameworks and packages such as Bootstrap and JQuery.

Bower compared to NuGet Packages
The NuGet client packages were sort of lame. I used NuGet for Font Awesome, and a couple of other front end packages, and had to go through all sorts of hoops to get them to work. Many of the packages were broken or outdated. Bower allowed me a very easy way to get the latest version of the package up and running in very little time, and did the dependency checking for me as well.

NPM
NPM is sort of like rpm in linux, that runs off Git, which is the git repository. You can download packages by command line such as npm install uglify -save-dev, which will download the package and save it to a package.json file, to use later.

Gulp
Gulp is a JavaScript file that uses the packages downloaded by NPM to customize your project. So with the package uglify, I can write a gulp command to minify my JQuery script files, add the suffix .min and publish them in my custom location.

Gulp can do many things, you can wrap script tag elements in HTML content and use Gulp to read the HTML, bundle those scripts and uglify them. Build customer CSS from Sass sources and minify them. So take for example JQuery 3.0 was released today, I think I'll just change the version number in my package.json and upgrade my project today, for it runs automatically.

Running Build and Clean
Put it all together, bind it to your project's pre-build, post-build and clean events, and you have a very powerful solution that is easy to work on and maintain.

VS2013 - Stripping MVC almost to the bare bones
Yes I had to strip my projects Nuget packages to the bare bones and figure out how to replace the functionality that Microsoft had injected into my project. What a mind bender as to what did those packages did in the first place? Microsoft was quite clever and had the intentions of producing the best possible results for an entry level MVC programmer, but I wanted more infinite control over how my project would be published for production use.

Razor
Well I just got my head out of the sand and realized that I don't have to use Razor. There are many other solutions out there such as Angular.js which actually looks more functional to me. But I have already started with Razor and will try Angular.js in my next project.

Deployment using Docker on Linux or Windows
I had no idea that Docker was out there. Docker is a container that includes a small version of your operating system and your production project. It's not a Virtual Machines, but the concept is similar. So you can develop in your Docker container, and just deploy the container to a cloud service or in house server. This eliminates the headaches that have long plagued us, in which hey it works in development but not in production.

And it doesn't have to be a Windows OS, you can develop on a Linux platform using the new Microsoft ASP.Net for Linux and Mono I believe. Build your Linux platform in Docker, and just deploy that Docker container to a Windows or Linux server running Docker.

Final thoughts
I'm really excited about this today. Makes me want to upgrade to Windows 10 and VS2015 to start using Dockers. I'd love to go back to Linux for serving my apps, and other open source programs and database servers.

I'm very happy with my current project right now! and see infinite possibilities with it today. I love the MVC platform and I'm not going back.

I wrote this because I still see the old webforms questions about Gridview, binding data to server controls, etc. And with all due respect, I think Code Project can use an upgrade in thread topics to cover these wonderful new technologies, and lead the way for all of us to benefit from them. I'd like to see some discussion on Node.js, and TypeScript.

I have many programmer friends that think MVC is sort of dumb, it's like classic ASP so whats the point? And I remember reading an earlier question as to why I should switch to MVC. So I hope this post provides a more convincing argument as to why MVC over webforms.

You guys and gals have a great weekend!

Thanks for the thumbs up John!

I went ahead and upgraded to Windows 10 from 8.1 and VS2015 from 2013 last Sunday.
I didn't know you can turn off almost all the BS in Win 10, and just run it straight.
It doesn't see all my ram, just half of the 32 gigs.

And the VS2015 is awesome, It has a JQuery and JavaScript lint checker that works very well.

My project is really cool now. When I publish, I can minify or ugligy all my Css, scripts, images to the production server, yet work with them raw in development for debugging.

So now on to the Sass, I need to learn that fast so I can create individual Sass files instead of Css and concat and minify them efficiently.

I guess I'm on my own now here with the new stuff. Perhaps others will read this post and jump on board.

I do like your thoughts on a place to talk about new stuff and the results were getting from it.

If you don't mind can you put some steps for each (Gulp , Sass, NPM) on how to install them and work on it. I am aware that I can get them online by googling but it will be more assuring if it is from someone we can check back.
