NerdDinner Tutorial
The best way to learn a new framework is to build something with it. This tutorial walks through how to build a small, but complete, application using ASP.NET MVC, and introduces some of the core concepts behind it.
The application we are going to build is called 'NerdDinner'. NerdDinner provides an easy way for people to find and organize dinners online:
NerdDinner enables registered users to create, edit and delete dinners. It enforces a consistent set of validation and business rules across the application:
Visitors can use an AJAX-based map to search for upcoming dinners being held near them:
Bishop jeffrey lee. Explore releases and tracks from Jeffrey Lee Pierce at Discogs. Shop for Vinyl, CDs and more from Jeffrey Lee Pierce at the Discogs Marketplace. Ramblin Jeffrey Lee Rare. GLITTERHOUSE RECORDS decided to concentrate on their own signings again. Over the years there’s a plethora of shining artists who recorded for Glitterhouse. (Ramblin' Jeffrey Lee and Cypress Grove with Willie love').
Clicking a dinner will take them to a details page where they can learn more about it:
If they are interested in attending the dinner they can login or register on the site:
They can then click an AJAX-based RSVP link to attend the event:
Implementing NerdDinner
We are going to begin our NerdDinner application by using the File->New Project command within Visual Studio to create a brand new ASP.NET MVC project. We will then incrementally add functionality and features. Along the way we'll cover:
You can build your own copy of NerdDinner from scratch by completing each step we walkthrough in this chapter. Alternatively, you can download a completed version of the source code here: NerdDinner on GitHub. You can also optionally also download a free PDF version of this tutorial if you want to read the tutorial offline.
Mar 08, 2013 It means, that our far cry 3 keygen generates one serial only once, if you generated a serial for yourself, you can be sure, that anyone els on earth won’t be able to generate one more like that from our keygen. Far cry 3 keygen free download.
You can use either Visual Studio 2008 or the free Visual Web Developer 2008 Express to build the application. You can use either SQL Server or the free SQL Server Express for the database.
You can install ASP.NET MVC, Visual Web Developer 2008 Express, and SQL Server Express (all free) using V2 of the Microsoft Web Platform Installer
Now let's get started..
Now that we've covered what NerdDinner is, let's roll up our sleeves and write some code.
We'll begin by using File->New Project within Visual Studio to create the NerdDinner application.
I've been checking out the NerdDinner tutorials. I was reading through the original PDF tutorial (http://aspnetmvcbook.s3.amazonaws.com/aspnetmvc-nerdinner_v1.pdf) that uses LINQ to SQL and MVC2. In that tutorial, they implement a data context and then implement repository classes to interact with the data entities.
I saw the project was updated to use MVC4 and Entity Framework (http://nerddinner.codeplex.com) so I browsed through that code to see what changes they'd implemented. They changed the project to be code-first with separate model classes for each data entity. I was surprised to see that they got rid of the repositories completely.
I thought it was generally good practice to abstract communication with the database through the repository pattern.. I know tutorials often make poor design choices for the sake of brevity, but I'm wondering why a tutorial that had already implemented repositories made the decision to omit them from this version.
Is there something in MVC4 or EF that makes repositories obsolete/redundant?

There is a long debate on whether it makes sense to wrap such advanced abstractions like the Entity Framework in repositories.
Historically, repositories were great. It was safe to have an extra layer of abstraction just to be able to switch between different data providers, plain old DataSets, files, linq, whatever.
However, many EF purists claim that EF is already an abstraction of the unit-of-work and repository with the data context being the unit of work and dbsets being repositories. They claim that the LINQ is the good enough abstraction of a query language and you don't need specific, restricted APIs.
Others say that this is not safe to assume that all possible providers are compatible in a sense that they provide consistent results for the same LINQ queries. Some providers could be limited and even refuse to evaluate specific queries. This - the people say - means that you still need an abstraction over EF so that you guarantee the same data contract for higher layers.
If someone decided to remove the repository layer from the example, this is possibly because of one of two reasons:
- someone realized that repositories just make the example more complicated and removed them for simplicity
- someone who is an EF purist would like to advocate the fact that 'nothing shall stand above EF'
Personally, I like repositories and use them whenever possible.

Wiktor ZychlaWith the increase of popularity of CQRS, the Repository pattern is kinda falling out of favour, with people like Jimmy Bogard making good cases against its use.
Basically, it's easy for a Repository to end up as a large class which knows how to form lots of different queries, violating SRP. Avoiding this in a complex system can end up giving you lots of Repositories, and using a Repository in a simple system is just over-engineering.
