F#

1. First official
functional
language on
.net

2. An introduction to
Microsoft's newest
official language,
F#,
geared toward C# and
VB.net coders.

3. See how
functional programming,
object-oriented programming
and imperative programming
can work together to provide
untold expressiveness.

4. If you wanna learn one new
language in next year, other
than Espanol & Hebrew ….
F# ought to be the one.

5. Imperative Programming
• FORTRAN (1954)
• COBOL(1960)
• BASIC(1964)
Functional Programming
• LISP (1958)
• ML(1970)

8. 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)
