I am using LINQ to SQL with C#.
Is there a method through which we can generate entity class files from the table schema?
By dragging tables onto the graphical designer classes are generated but they are not the real class files(i mean actual files with the extension cs).

I am aware of that we can code the class files first and then create the schema manually or programmatically, but i wanted to know if the reverse is possible, may be using some third-party tools. I feel it will be very convenient to use LINQ that way.

Thanks in advance.

    I’m not as familiar with LINQ to SQL as I am with Entity Framework (v4), but EF certainly would fit your requirements. You can download the POCO templates for EF from Microsoft, right through VS2010 in the Extension Manager (Tool > Extension Manager, click on Online Gallery, and search for POCO). The link is not just the download for the template, but a walkthrough on how to get started.

    I also have started a series of blog posts that include some nice T4 templates for an Entity Framework EDMX model that auto generate DTO classes for all of your entity classes, whether you’re using the default code generation model, or Microsoft’s POCO template. The auto generated DTOs are handy for use in UI or service layers, and save you from having to bring in dependencies on Entity Framework in consuming layers. It’s also very easy to get DTOs from your entity objects.

    var people = from p in context.People select p;
return people.ToDtos();

    Might be worth a look (shameless self promotion).

    If you need/want to stick with LINQ to SQL, do a google search for "linq to sql POCO", it seems some people have had a degree of success with this, but most of the search results seem to be from 2008 and earlier, so I’m not sure about currency / relevancy.
