This question already has an answer here: Is it possible to write a Ping class in C# that will run within Windows 8 Metro environment? 1 answer How to do an ICMP ping in a WinRT Modern UI application? Ping is not implemented in WinRT currently (see related question here ) and the previous strategies in Silverlight being: Use a WCF Service Call Javascript which then calls an ActiveX component Give up ( here ) Vasily here uses http to 'ping' a webserver on a specific port using StreamSocket which supports network communication using a TCP socket. Perhaps Windows.Networking.Socket s is the

I'm trying to save a string of user inputs to a file in a windows runtime app. However I'm getting the error System.UnauthorizedAccessException . How do I gain access to this Library? static private async Task WriteDataToFileAsync(string fileName, string content) { byte[] data = Encoding.Unicode.GetBytes(content); var folder = KnownFolders.DocumentsLibrary; var file = await folder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting); using (var s = await file.OpenStreamForWriteAsync()) { await s.WriteAsync(data, 0, data.Length); } } "Documents library" capability in Visual Studio

I am looking for the list of assemblies in the ".NET for Windows 8" profile. This is the profile used for WIndows 8 Metro-style applications, and like Silverlight doesn't use the full .NET framework. .NET for Metro style apps — list of namespaces Converting your existing .NET Framework code — changes to the various APIs. I don't see any list currently... and WinRT is expected to change alot till the official release in 2012... current information about assemblies/not available in the "Metro/WinRT Client profile": http://blogs.microsoft.co.il/blogs/sasha/archive/2011/09/17/metro-net-framework

I am building Windows Store Application (Winrt, Metro, Windows 8 app). I try give images in gridview animation: after image is loaded from web and opened it populates its cell. I have storyboard for that: <Storyboard x:Name="PopupImageStoryboard"> <DoubleAnimationUsingKeyFrames EnableDependentAnimation="True" Storyboard.TargetProperty="(FrameworkElement.Width)" Storyboard.TargetName="image"> <EasingDoubleKeyFrame KeyTime="0" Value="100"/> <EasingDoubleKeyFrame KeyTime="0:0:0.1" Value="240"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames EnableDependentAnimation="True"

I am writing a class that will convert a HTML document to a list of Paragrpahs that can be used with RichTextBlock in Windows 8 apps. I want to be able to give the class a list of Styles defined in XAML and the class will read useful properties from the style and apply them. If I have a Windows.UI.XAML.Style style how do I read a property from it? I tried var fontWeight = style.GetValue(TextElement.FontWeightProperty) for a style defined in XAML with TargetProperty="TextBlock" but this fails with and exception You could try this: var fontWeightSetter = style.Setters.Cast<Setter>()

I'm currently developing a WinRT app where I load local HTML files from Windows.Storage.ApplicationData.Current.LocalFolder . I like to know what would be the best way to load assets like Images, Audio, Video, CSS, JavaScripts, etc, that are embedded in the HTML file. Currently, I'm writing these files in the Windows.ApplicationModel.Package.Current.InstalledLocation but this wont be accessible anymore once the application had been deployed from the store or by installing the AppPackage through Windows PowerShell, unless you change the ownership of the "Program Files/WindowsApps" folder to the

I have a question regarding SignalR's official documentation - Hubs API Guide - .NET Client . In the section - How to establish a connection . It has been written the following thing: The Start method executes asynchronously. To make sure that subsequent lines of code don't execute until after the connection is established, use await in an ASP.NET 4.5 asynchronous method or .Wait() in a synchronous method. Don't use .Wait() in a WinRT client. Does anyone know what is the specific reason not to call Wait()? Also, does also this apply when I have a WinRT client where I have a call with hubProxy
