Methodology
emids, by virtue of being an industry player for over a decade has contributed immensely to the internal as well as external developer community, adding value to existing clients.
To further its endeavor, emids presents an application starter kit using Model View Controller (MVC) architecture. This kit enables development to begin with a pre-existing set of constructs rather than developing from scratch.
Why application starter kit?
All application and/or product development entails certain basic "must haves" like administration, authentication, seamless performance etc. Every new project or product development or client initiated exercises normally start from scratch, although we do realize that a lot of common constructs exist. The emids Application Starter Kit is designed to address this.
The Starter Kit for developers is a fully functional sample application to help one learn and accomplish their common development scenarios. The sample is complete and well-documented so that one can use the code to kick start projects right away! The benefits extend to productivity as well as cost. After downloading and installing the Starter Kit, please send comments/clarifications to askmvc@emids.com
Description
MVC architecture allows us to separate different parts of our applications into different layers. This allows developers to have a better separation of concerns which results in better reusability and easier testing. This framework gives better control in the order in which the things happen during the page lifecycle, of the way state is persisted between requests, and the code with which HTML is rendered. This framework is not a replacement for the web-form programming model, but it is an alternative programming model, for those who want to have better control.
MVC, which stands for Model-View-Controller, separates an application in three components: Model, View and Controller.
Model
This contains the Business logic and Data Access which has a set of classes that would define the functionality of the application from the business perspective. It contains model classes which are used to model objects in the application's domain.
View
View contains HTML markup and view logic. It can consist of every type of interface given to the user. The view is the set of web pages presented by an ASP .Net web application.
Controller
Controller is the object that allows the manipulation of the view. In an ASP.NET application the controller is implicitly represented by the 'code-behind' or the 'server side code' that generates the HTML presented to the user. It interacts with MVC Models and Views to control the flow of application execution.

The steps to get started with application starter kit are outlined below:
Pre-requisites: You need to have Visual Studio 2008 Sp1 and SQL 2005 (Express) or above.
- Download and Install the MVC framework from http://www.microsoft.com/downloads/details.aspx?FamilyID=53289097-73ce-43bf-b6a6-35e00103cb4b&displaylang=en
- Attach the database provided with the Application StarterKit as AWorksDB (In SQL Management Studio, right-click on database and choose Attach. It needs the mdf and ldf to be in the same place. If it gives an error, remove from ldf from the list of files - it will create a new one)
- Enable the membership database by running c:\Windows\Microsoft.NET\Frameowork\v2.0.50727\aspnet_regsql. This step should create a new ASPNETDB in SQL Server.
- Open the attached solution and in the web.config set the connecting strings for
<connectionStrings>
<add name="ApplicationServices" connectionString="data source=.;Integrated Security=SSPI;Initial Catalog=aspnetdb" providerName="System.Data.SqlClient" />
<add name="AworksDBEntities" connectionString="metadata=res://*/Models.EFX.AworksDB.csdl|res://*/Models.EFX.Aworks
DB.ssdl|res://*/Models.EFX.AworksDB.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.;Initial Catalog=AworksDB;Integrated
Security=True"" providerName="System.Data.EntityClient" />
</connectionStrings> - You should now be able to run the application and register a new user and login to the system
NOTE : The Controller has a Authentication Filter for a specific user. In the sample, this is set to
[Authorize(Users = "ps2")]
Change this to a user that you have created as part of the registration process.
