I just learned of the existence of a very interesting tool called LinqPad, which allows query data using LINQ with. Net Framework 3.5.

Allows queries like:
a) LINQ to SQL
b) LINQ to Objects
c) LINQ to XML
After doing some tests I can say that is an excellent tool, very comprehensive and allows flexibility to experience the power of LINQ and more of this interesting framework, which aims to be the big bet. NET for data access.
