I have a dispute with my colegue about how Entity Framework interacs with MS SQL SERVER.
We are arguing about if Entity Framework loads all the values from Db tables in Objects or not.
EDITED: when we select data using LINQ i my opinion LINQ query works with entity objects not direct with tables so the information in objects where previously obtained from the table.
The whole idea behind EF is to solve the impedance between relational an object oriented worlds, so, I don't see the point in your question..

I have a database schema. How do I construct a family tree using asp.NET, C# and SQL server? Also, how can I show you the database schema?
I suggest you take a look at Family Show, a WPF application which enables you to view and/or edit a family tree. I think that with some tweaking you will be able to make it work against SQL Server using your database schema.

I'm new to ASP.net and coming from a Ruby on Rails background. I have 3 tables in question they are Booking, Customer and Contact (contact being customer contact details). Basically what i want to do is have one form which will create all of the objects required in one go, so if i create a booking it also creates a customer and their contact details. I am familiar with this process in Rails which is accepts nested attributes for. I'd appreciate any pointers for a similar solution in ASP.net
I'd recommend learning Entity Framework as an ORM for this application.

Is 'Database Driven Development in windows' same as Application development uses Entity Framework. or is this (DB Driven Dev) has to use different framework or design?
Please comment. Thanks.
Database Driven Design is basically where you have the database design done first, then you program an application based upon the database. Database driven design
Entity Framework is a Object Relational Mapping tool. Using EF, you can do a "code-first" database design where EF will create your database for you, but that's still not database driven design.

I want to generate C# code automatically, for data access in my asp.net projects. Which of the approaches (also why) is more suitable for automatic C# code generation: Entity Framework or ApexSql Code?
Please note that I'll be updating db model from time to time. I want to do this with minimal effort (e.g. without need to run a sql diff tool if possible).
I may be wrong, but I don't think ApexSql has code generation like EF. From what you have mentioned, it sounds like you want EF Code First.

in C# ::I need to use a table for 2 school classes, i am using a table for one now, but i need to use a table same as this, for another school class. how can i do this?
how many DataAdapter, DataSet or SqlConnection do I need?
Not knowing the exact structure of your database surely don't help to answer precisely to your question but considering the info you provided, if you use the same database engine for both of your tables, you can use one SqlConnection and as many DataAdapter, DataSet as you wish.
But you should establish a correct design of your database first and submit it would help everybody to give you a better answer than this one:-)
