@17:55 i got the following error. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. what to do?
I’m trying to do it right now and I have an error when trying to connect the controller at 7:01 minutes . I have an error that pops saying “There was an error running the selected code generator: ‘Could not load file or assembly ‘Entity Framework, Version =5.0.0.0, Culture = neutral, PublicKeyToken =b77a5c561934e089’ or one of its dependencies.

Instead of : webAPIClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json)")); USE: webAPIClient.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose"); It works!

The best tutorial I've seen, good job you example is the best example I've seen, only I some question, can I use a Web Services with Entity Framework action ? if you have any example for this kind problem is a good idea you try to explain, my second question is when I made my CRUB I have a item of datetime type, I use a datepicker but I have a problem whit the day when the day is major or equal to 13, I save the day in this format "mm/dd/yy" but when I recive the day in my controller I recive a parameter null, Why can you explain me this please? what I need to do for fix this problem; my last question is How to remove the hour in a field datetime, thank you
seems that your date and month are mixed up. Your computer may be receiving in USA format "mmddyyyyy" and the control might be sending in english format "ddmmyyyy" or vice versa.
I can't call the HTTP method from the WebAPI project in my WebApp thorugh implementing the insert operation" in my WebApp employee controller. I cannot define the GlobalVariables (it doesn't show up). I assume it is because my WebAPI project (which in my case communicates with my MS SQL server db using EF Migrations) is a separate solution from the WebApp. You seem to have both the WebAPI and the Website in 1 solution. Any advice?

Solution: Add a reference to System.Net.Http.Formatting.dll. This assembly is also available in the C:\Program Files\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies folder. The method ReadAsAsync is an extension method declared in the class HttpContentExtensions, which is in the namespace System.Net.Http in the library System.Net.Http.Formatting.

Hello i reslove this error suceessfully , you just need to correct port number => new Uri("localhost:44345/api/"); here 44345 is api port number in your localhost just like in your local webapi project mention correct port number and it will work..........
great tutorial , i never found like this one, if we have knowledge on concept we never feel work pressure, keep doing more videos, my humble request is to do a video on django framework similary by taking like this small project , thanks a lot
thanks for sharing your thoughts here. I'm working on my python. hopefully django framework tutorial are on the way. I would be waiting for your feedback once it is done.
You are welcome. Web API is mostly used as API (only back-end operations without front end). So that other client side and mobile applications can consume WebAPI methods. Asp.Net MVC is used to create applications for server side or client side operations or both. Nothing is better than other both has it's own special features. If you need an application in browser and mobile application. you can create a web api and then consume the same from Asp.Net MVC for website. same WebAPI can be consumed from mobile applications (android,ios,windows phones etc). On the other hand, suppose you need only a website without mobile apps you can develop the complete website in Asp.Net MVC.
depends upon your requirement. Normal crud operation includes reloading of the page after form submission in case of jQuery Ajax CRUD we can avoid that.

This is very helpful tutorial. I have used this as reference for me practice. In my database I have two tables like project and costcenter. Costcenter having project as foreign key. Now how I can create screens for this.
Followed the tutorial, Thank You! One issue I am having, is that I cannot see the values stored in the DB with the api/{controller} link. It doesn't give an error message besides "No HTTP Resource was found that matches the request URI." I checked the controller and referenced it with yours, and everything checks out. What could I have missed? Thank you!
I had the same issue - firstly make sure your table in DB is populated. Secondly make sure you are referencing the correct controller name. Another things - are your methods returning Views (if yes - then this is wrong). Just paste whatever you have on top of the method after Get/Post/etc epi/{controllerAction}

return View(empList);
}
Notice I had to use ""Employees" instead of "Employee" inside of the ( ) on the fourth line of code. Using "Employee" gave me the same error. Also I truncated the Employee table in SSMS as well..just to be safe but I don't know if that made any difference. I hope this helps.

Hello can anyone please help me with this error : 'object' doesnot contain a definition for 'result' and no accessible extension method 'result' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)
Very helpful, keep the good work :)
Glad you found the video helpful.
Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.IEnumerable`1[employeeMVC.Models.MvcEmployeeModel]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.

I had this error and it was because I had the wrong URI in GlobalVariables. Make sure your URI is pointing to the Web API. You can get your project URI by right clicking on WebAPI project -> Properties -> Web.

Hi, if I want to implement the "Details" function to show the specific user details, may I know how to do that ?
use this controller

public async Task Details( int id )
{
HttpResponseMessage response = GlobalVariables.WebApiClient.GetAsync("Employees/"+id.ToString()).Result;
var responseContent = await response.Content.ReadAsStringAsync();
var Employee = JsonConvert.DeserializeObject(responseContent);
