Windows Phone上的F#报价 [英] F# quotations on Windows Phone

问题描述

我在Windows手机上使用Daniel Mohl的F#模板，但是似乎捆绑的FSharp.Core没有一些引号代码.我正在尝试从常规.NET移植此代码:

open System.ComponentModel
open Microsoft.FSharp.Quotations
open Microsoft.FSharp.Quotations.Patterns

[<AbstractClass>]
type ViewModelBase() =

    let propertyChanged = new Event<_, _>()

    let toPropName expr =
        match expr with
        | PropertyGet(a, b, list) -> b.Name
        | _ -> failwith "Unsupported: " + expr.ToString()

    interface INotifyPropertyChanged with
        [<CLIEvent>]
        member x.PropertyChanged = propertyChanged.Publish

    member x.NotityPropertyChanged expr =
        propertyChanged.Trigger(x, new PropertyChangedEventArgs(toPropName expr))

但是编译器抱怨Microsoft.FSharp.Quotations.Patterns和PropertyGet.似乎它甚至都不知道Expr类型. 关于如何解决这个问题有什么想法吗?

解决方案

我用

But the compiler complaints about Microsoft.FSharp.Quotations.Patterns and PropertyGet. It seems it doesn't even know the Expr type. Any idea on how to solve this?

解决方案

I replaced the FSharp.Core file that comes in the template by the one that comes in the F# April 2011 CTP in the WindowsPhone7\Silverlight\4.0\bin folder, and with this version it now compiles fine
