Is it possible to use F# to develop Windows 8 Universal App

I would like to use F# to develop windows 8.1 universal app. So I have created F# portable library. But unfortunately I can not open Windows.Storage namespace on it.

Then I have created C# Windows Apps Class Library where I have implemented the function I was needed:

 public static async Task<string> ReadFileToString(string filename)
 {
        StorageFile file = await StorageFile.GetFileFromPathAsync(filename);
        string fileContent =  "";
        fileContent = await FileIO.ReadTextAsync(file);

        return fileContent;
 }

Then I want to Add Reference in my F# Portable Library to this C# Library but get the error message, that

"it is impossible because the project is designed for platform (.NETCore) which different from current (.NETPortable)"

It is possible to use F# to develop windows 8 universal app ?

Here is the solution I have found.

  • Install PCLStorage using NuGet to F# portable library and Windows 8.1 Store App (!)
  • Set "Copy to Local" = False in F# library (!)

Here is code of f# library:

namespace PortableLibrary1

open PCLStorage

type MyClass() =
    member this.Do (filename : string) (text : string) = 
        let folder = FileSystem.Current.LocalStorage       
        async {
            let! result = Async.AwaitTask(folder.CreateFileAsync(filename, CreationCollisionOption.ReplaceExisting))
            result.WriteAllTextAsync(text) |> ignore        
        } |> Async.RunSynchronously

And here is a C# Store App code:

 private void Button_Click(object sender, RoutedEventArgs e)
 {
    MyClass cls = new MyClass();             
    cls.Do("uuu.ii", "message of me");
 }
