Exception while trying to read file usin PCLStorage from PCL project

Question

I am trying to get file from PCL project using PCLStorage as below. I am using Xamarin in Visual Studio 2015 Professional.

IFile file = await FileSystem.Current.GetFileFromPathAsync("file\path");

But I am getting exception as:

System.NotImplementedException: This functionality is not implemented in the portable version of this assembly. You should reference the PCLStorage NuGet package from your main application project in order to reference the platform-specific implementation.

You need to add the PCLStorage NuGet to both your PCL and your platform specific project.

So if you have the following solution:

PCL
Android
iOS

You would need to add it to all of them:

PCL
    PCLStorage
Android
    PCLStorage
iOS
    PCLStorage

Why? Because the NuGet uses the bait and switch technique, where the PCL contains a simple facade with the bait. At runtime this gets switched out with platform specific implementation.

Thank you, exception gone, but GetFileFromPathAsync returning null, even though I have valid file in the location – subha Oct 12 '16 at 12:34
I am trying to read file which I have added in my PCL project, not from local storage, Is that possible or not? – subha Oct 12 '16 at 12:37
Yeah, but it is not related to PCLStorage plugin. – Cheesebaron Oct 12 '16 at 12:38
