Entity Framework Console Applications with SQL Server Compact

Microsoft SQL Server Compact Edition is an embedded database system that allows us to integrate it in our Web, Desktop and Mobile applications.

Entity Framework's Database Seed Method

The Entity Framework can automatically create/update/drop databases when the application runs. We can specify that, this should be done every time application runs or only when the model is out of sync with the existing database or in other word it runs whenever model changes.

Media Only Queries in CSS3 / @media only screen and (max-width: 900px) { attributes; }

If you remember, CSS2 added support for the media="screen" way of defining which stylesheet to use for which representation of the data.

Now CSS3 added a new feature to this functionality, by adding media queries. Basically, this means you can change stylesheets or styles on the web page based on for instance the width and height of the viewport/browser.

The type 'System.Data.Objects.ObjectContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

Today, I was developing an web application, I got titled error. I decided to post the fix for this.
