I am trying to find proper place where can i get all updates regarding EF 4 as we are going to use it for our new project.
Is there any team blog for EF4 from microsoft?
Any other online source?

Entity Framework 4.0 Resources – documentation links, best blog posts and more
Julia Lerman (author of "Programming Entity Framework") also has a lot of informationn on her blog Don't Be Iffy and on her book web site, Learn Entity Framework. She's currently updating her book content to reflect EF4.

This is probably an obvious question to many but I'm scratching my head over this one.
Can someone explain to me what purpose/advantage generating POCO classes via t4 templates such as the ADO.Net DBContext Generator has over standard EDMX data access?
I understand that they offer extensibility over the entity class definitions, but if a development team is not interested in that what other obvious purpose or advantages do they have?
Thanks
As mentioned by ThomasH in the comments the provided link gave me the info I needed.
Would somebody please guide me towards links that explain Fluent API and Annotations when using EF 4.1 code first please? The more in depth, the better.
Thank you so much for your help in advance!
May issue of MSDN magazine contains article about EF 4.1. For further information check these blogs:
ADO.NET team blog
Morteza Manavi's Blog
Julie Lerman's Blog
You can also check this video but for that you need a subscription ($29 per month).
Almost everything can be found on Stack Overflow ;)

Can anyone help me to write an Application using ASP.NET MVC 2 and LinqToSQL??? also explain the Repository Pattern!!!
Unless you specify what kind of help, it's very hard to answer your question. This article from Scott Gu might help you get started with linq to sql.
Here's a link to another article on the repository pattern, and here
Is ADO.NET 4 the same as Entity Framework 4? I'm looking for a book on Entitry Framework and saw this Title. Not sure if what I'm looking for though.
Thanks
No, it's not. Entity Framework is an ORM that has been built on the top of ADO.NET. Although the book you've mentioned has a small chapter on EF, but its main focus is on ADO.Net basis and its core classes.
If you are looking for a book on EF, then don't miss this GREAT book, it's all you need:
The official name for "Entity Framework" is "Microsoft ADO.NET Entity Framework".
A book on ADO.NET 4 should include information about Entity Framework 4 but you might be better off with a book focused solely on the topic.
Here's how MSDN defines the relationship between them:
The Entity Framework is a set of
technologies in ADO.NET that
support the development of
data-oriented software applications.

I currently enjoy working with NHibernate + Fluent NHibernate. I considered Entity Framework v1 because of its mature Linq support but I do not like working with clicky designers; and it did not support POCO, anyway. Now EF v4 does support POCOs; however, does it still require to use designers? Well, maybe I can edit those XML files but it cannot be considered a programming activity (unless you're doing J2EE I think).
So, would I be able to use Entity Framework only from the C# code, including model definition, etc?
Yes,
There is an add-on to .NET 4.0 that allows you to do this without a designer, it is called Code-Only you can find it here: In the CTP for Beta 2
The current version works against EF / .NET 4.0 Beta 2.
Check out this post on the EF design blog more on how to use Code-Only.
Also check on this post on my blog.
Hope this Helps.
