The last one ( Code First) is the one I have used for this application and frankly speaking it is gaining in popularity amongst developers. We have Database First,Model First and Code First. I have developed my data access layer with EF. I am going briefly to introduce Data Annotations and how to use them in our Code First Entity framework applications. The Comment field will only be 100 characters long and also mandatory.We also want to have the characters for the Name property of the Movie entity restricted to 70 and the name of the Director restricted to 50 characters.īoth of these properties should be mandatory. I want to have a validation rule applied to the Rating field that will accept only values 1 to 10 and it will be mandatory. Right now there is no validation for the fields Rating and Comment of the MovieReview entity. In this post I will add some validations to our application through Code First Data Annotations and migrate those changes to our database through EF Code First Migrations. Make sure you read and understand those posts. You can find the first one here, the second one here, third one here, the fourth one here and the fifth one here. I have decided to write a series of posts on how to write a small ASP.Net MVC 4.0 application.I will develop this application step by step and I will explain everything that you need to know in order to develop ASP.Net MVC 4.0 applications.
