Understanding language features that make LINQ possible

There are several features available in C# that are either necessary for the implementation of LINQ or that help us effectively use LINQ queries. These are some of the topics that we will be going through in this chapter:

• Implicitly typed variables
• Object initialization syntax
• Lambda expressions
• Extension methods
• Anonymous types

Implicitly typed variables

In C#, we generally use statically typed variables. This implies that the compiler knows the type of variable at compile time. Due to this, if it finds any operation that may result in an error, it will highlight it at compile time. For example, refer to the following code:

 int i = 1;
 FileStream f = new FileStream...
