I am a c# business developer, not a DBA nor a Database Developer. I have fair notions & skills, but I love straightforward tools to unburden the load of simple database modeling and creating quick c# DALs so I can focus on business logic.
I have been using Telerik ORM and AgileFX ORM (pic below)
Both have nice VS2010 plugins, but the first is not free, and the latter is not actively maintained, and has some weird annoying modeling bugs from time to time (though it fits exactly my plain-and-simple needs)
What free easy plug-and-play tools would you advice that could meet my expectations ?
I am using SQL Server, DB Scheme is already set. I just need to import & create a Data Access Layer for it.

Edit :
As pointed out by an answer, I feel a bit stupid using Tier Application when there are built-in tools as Linq-to-SQL. Nice tutorial here
Entity Framework and Linq-to-SQL are both built into Visual Studio.
