This course covers F# in the work-a-day world, with a focus on porting and interoperability.

What you will learn

• How to port code to F#.
• How to interoperate with existing Microsoft technologies such as:
  • Other .Net languages (C#, VB.Net)
  • LINQ
  • XML
• How to leverage F# in conjunction with typical application programming scenarios:
  • User Interfaces
  • Web Programming
  • Databases
  • Distributed Computing
  • Scripting
  • Windows Services

1. Interop
   • F#
     • Expressively powerful
   • C#
     • Mature IDE
     • Existing code bases
   • How do you get the best of both worlds?
2. Intersection with C#
   • C# has some functional facilities
   • What F# structures look like in C#
3. Imperative Conversion
   • Converting imperative code to functional
   • Immutable structures are thread safe
   • Sometimes mutation gains efficiency
4. Tail Recursion
   • Refactoring non-tail recursion
     • Tail recursion
   • Tree recursion
     • Requires continuations
     • Trade stack space for heap space
5. Debugging
   • Breakpoints
   • Assertions
6. Scripting
   • Batch jobs
   • Running F# without Visual Studio
7. IO
   • Streams
   • Piping
   • Use
8. Databases
   • Interacting with databases
9. Web Programming
   • ASP.Net
     • ASP.Net MVC
   • WebSharper
   • Web Services
   • WCF
10. Distributed Computing
    • Remoting
    • Serialization
    • WCF
11. Windows Services
    • Threading
    • Installers
    • Debugging
    • Event Logging
12. GUI
    • WPF
      • Plays well with functional programming
      • IDE for XAML not currently available
      • Silverlight
    • Win Forms
      • Existing code base
13. Units of Measure
    • Type system "rider" for numeric types
    • Compile time checking for unit usage
    • Type erasure
14. XML
    • LINQ XML
      • Functional composition
    • Active patterns
      • For parsing XML
15. LINQ
    • Can leverage LINQ
    • Less necessary in F#
      • Seq + |>
