DisFunctional programmers

•I write Windows applications!

•Integration

•XML Parsing, database access

•Whine to mommy

DisFunctional programmers

•F# runs as an external tool inside of Visual Studio

•some of the seamlessness that developers get with C# or Visual Basic is missing

•F# also lacks ASP.NET page designer support

Resistance is Futile

•"many languages, one platform“

•safe concurrent programs

•discourages the use of null values and encourages the use of immutable data structures

•more succinct

•dynamic language
