Can someone suggest us a good c# database programming book (cFour.). I personally use visual studio 2010 and I am just beginner of database programming .

Head First C# is actually great for beginners.

fundamental SQL etc Beginning C# 2008 Databases: From Novice to Professional

And when you need to find out about linq to sql: Professional LINQ: Language Integrated Query in C# 2008

The only real .Internet 4. book I possibly could find on databases is:

Microsoft ADO.NET 4 Step by Step (Step By Step (Microsoft))

Arrives in a few days.

You'll need a bestseller on ADO.Internet.

You are able to definatly consider these freely available books

You will need to look underneath the .Internet section

I would suggest any black book by Microsoft Press, like Microsoft ADO.net step by step.
