i got lost on 17:38 because i couldn't find the reference to ReadAsAsync 'System.Net.Http.HttpContent' does not contain a definition for 'ReadAsAsync' and no extension method 'ReadAsAsync' accepting a first argument of type 'System.Net.Http.HttpContent' could be found (are you missing a using directive or an Assembly reference?)
@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.

COULD SOMEONE HELP ME? On minute 19:28 I have an exception error: "JsonSerializationException: Cannot deserialize the current JSON object..." The error occurs on the line: empList = response.Content.ReadAsAsync().Result;
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.
@CodAffection can you please share which nuget packages you have added in WebApi & Mvc, coz after completing project data is not updating & deleting from front end. Or anyone can please. Preparing for interview.
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.
I am getting error on timestamp: 09:28 of your video. Error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

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?
Instead of : webAPIClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json)")); USE: webAPIClient.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose"); It works!
Nice explanation for startup! Css doesn't work have copied from project download link, but for my case Create New open in same window itself not as popup. Please help.

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.

Which method is best for crud in MVC application... Normal CRUD or jQuery Ajax CRUD ???
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.
Excellent
