Iteration #1 – Create the Applicationhttp://www.asp.netSat, 12 May 2012 19:20:54 GMTumbracoComments for Iteration #1 – Create the ApplicationenComment Posted by DarrallBhttp://www.asp.net/mvc/tutorials/older-versions/contact-manager/iteration-1-create-the-application-csFri, 18 Jun 2010 12:43:35 GMT00000000-0000-0000-000000009146I appreciate the fact that this tutorial is presented for free but there is little value in making a presentation if it doesn't work. Did you try and create this application instruction by instruction? It won't work.

Just for example in listing 2 your instructions are to create the object _entities. This cannot be done without inserting the using statement "using ContactManager.Models;"

Below that you have "return View(_entities.ContactSet.ToList());"

There is no ContactSet. Their is Contacts. That works.

There is lots more. Or did you intend for the student to hunt these down?

It does that for any table you rename using the properties area in EDM. You must have skipped the step where you rename the table from the plural Contacts to the singular Contact. Also, the using statements should be second nature. I can understand your confusion if you are a new to .Net, but whenever you need a using statement, the system will show you. The author didn't say that this is a tutorial on the .Net language. If you need that, you should get that knowledge first BEFORE trying to attempt this example.

select the table model, right click properties, under the properties you will see the "Entity Set Name". Rename that to ContactSet and problem fixed! p.s i had to research this XD

Any idea what I may have done wrong? The database field is an identity field, and I icluded [Bind(Exclude = "Id")] on the Create method.

1. Renaming Contacts to Contact happens automatically in MVC2

2. Even when I have 'using ContactManager.Models;', my compiler still underlines ContactManagerDBEntities and says it expects a class, delegate, interface, enum or struct.

3. Adding a using statement is only second nature when referencing a class. In MVC, finding the class ContactManagerDBEntities, or even realizing one was created, is not intuitive.

@cbueno2, I see no "Entity Set Name" property for ContactManagerModel.

@ the author of this article, your article sucks. Please don't post useless articles.

I tried to set "Identity Increment" and "Identity Seed" = 1 for "Id" column to test this. If I manually create new one in VS, the value of this column will increment with seed value = number of clickings "Create" button in application + total of record in Database.

Why data is not shown in database?

There were differences but they are down to the fact I'm using MVC2 and this tutorial was written for MVC1. The article states it's for VS2008 so that's fine.

Sure there's some slight ommissions such as not including the using statement but nothing that can't be worked out. The fact that the namespace error was for a class called ContactManagerDBEntities should tell you that it's going to be located in a namespace under ContactManager and you've only got Models or Controllers to choose from.

TH edit aspect of this video simply will not work for me... I have duplicated the code exactly several times and I continue to receive the same error EVERY time I try;

The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Edit(Int32)' in 'Program.Controllers.ProgramsController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.

Parameter name: parameters

wtf does this mean and how the heck do I resolve this? it happens all the time; even with [Bind(Exclude="ProgramId")] used in Create

Oh how I desire to follow a lesson series that actually works!

You've managed to explain the SOA design principles in a concise, yet effective package.

This is really helping me make my practices better!

This

"Contact c = _entities.Contacts.FirstOrDefault(s => s.Id.Equals(id));"

instead of this

" var originalContact = (from c in _entities.ContactSet

where c.Id == contactToDelete.Id

select c).FirstOrDefault();

"

But, overall I felt this was very good. With the platform changing slightly almost every day a perfect tutorial is almost impossible. Digging for how you make your version work is most of the real learning process

Not useful at all.

This was a pivotal article for me in understanding good design practices. Thank you. I like how simple and useful the application you chose to demonstrate the concepts. That's how I learn personally.

Any chance you can make a PDF available so I can keep this excellent tutorial.
