First official
  functional
language on
     .net
An introduction to
 Microsoft's newest
  official language,
           F#,
geared toward C# and
   VB.net coders.
See how
functional programming,
object-oriented programming
and imperative programming
can work together to provide
untold expressiveness.
If you wanna learn one new
language in next year, other
 than Espanol & Hebrew ….

  F# ought to be the one.

• COBOL(1960)
• BASIC(1964)
Functional Programming
• LISP (1958)
• ML(1970)

F#
F# Interoperability
• F# is compiled on .NET 2.0
• You can use .NET libraries in F#
  – dot notation for working with objects.
  – “<-” operator for modifying values of properties.
  – delegates created using lambda functions.
• You can use F# libraries in any .NET language
  – F# libraries fully accessible from C#
  – (sometimes a bit tricky, because of F# functional approach)
