Domain Modeling in F# with Tomas Petricek

Tomas moves to some higher level F# constructs by explaining Type Providers.
Tomas is just an excellent person. I really enjoyed picking his brain as he worked with Type Providers.
There are four videos in this series if you would like to skip around:
Would love your comments!
It could be good if there was a section on SQL database type providers (like https://github.com/fsprojects/FSharp.Data.SqlClient) because it's far more practical in real programmers life and it is real viable alternative to ORM frameworks that use code generation.
I can't seem to get FSharp.Data to work in my Windows 8.1 app. I added an F# portable library to the solution and when I use Http.AsyncRequestString, I get a System.InvalidOperationException: The API 'System.Environment.get_OSVersion()' cannot be used on the current platform.
Is this a known issue?
@bellp: I logged an issue here: https://github.com/fsharp/FSharp.Data/issues/858. Please watch the discussion there - we might need more info from you :)
