How LINQ works internally?

Question

I love to use LINQ on .net, but I wonder to know how does that works internally?

Does anyone know that?

Thks.

Answer 1

LINQ is basically a combination of C# 3.0 discrete features of these:

• local variable type inference
• auto properties (not implemented in VB 9.0)
• extension methods
• lambda expressions
• anonymous type initializers
• query comprehension

For more information about the journey to get there (LINQ), see this video of Anders in LANGNET 2008:
