Bindings are not supported on Setters. I think Silverlight only got them in version 5 if at all. For workarounds you can look at my older article here. Basically you define an attached dependency property that sets up the binding for you.
I’m porting my existing project to Win8 right now. It consists of windows service and tray application which are talking to each other via NamedPipes WCF. As you may already know Metro doesn’t support named pipes. I ended up using TcpBinding for full duplex connection. This post describes what functionality is supported. Sample of my … Read more
At the lowest level, WinRT is an object model defined on ABI level. It uses COM as a base (so every WinRT object implements IUnknown and does refcounting), and builds from there. It does add quite a lot of new concepts in comparison to COM of old, most of which come directly from .NET – … Read more
Color distance is not a precisely defined thing. So here are three methods to measure it: One method that checks only the hues of the colors, ignoring both saturation and brightness One that only measures the direct distance in RGB space And one that weighs hue, saturation and brightness in some way. Obviously you may … Read more
It’s easier to directly get the CoreWindow from the non-UI thread. The following code will work everywhere, even when GetForCurrentThread() or Window.Current returns null. CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, <lambda for your code which should run on the UI thread>); for example: CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { // Your UI update code goes here! }); You’ll need to reference Windows.ApplicationModel.Core … Read more
From .Net 4.5 onwards: Use IProgress<T> Since .Net 4.5 you can handle asynchronous progress reporting with the IProgress<T> interface. You can write an extension method for downloading files using the HttpClient that can be called like this where progress is the implementation of IProgress<float> for your progress bar or other UI stuff: // Seting up … Read more
A quick and dirty solution is to use the ServicePointManager.ServerCertificateValidationCallback delegate. This allows you to provide your own certificate validation. The validation is applied globally across the whole App Domain. ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true; I use this mainly for unit testing in situations where I want to run against an endpoint … Read more
Suspending event won’t fire while you are debugging (but while running your App normal, it will fire just after you navigate away from the App) as it is said also at this blog: …you will wait forever for these to trigger, even though your app switches back and forth to the screen! The reason is … Read more
Do not use regex delimiters: name = Regex.Replace(name, @”\W”, “”); In C#, you cannot use regex delimiters as the syntax to declare a regular expression is different from that of PHP, Perl or JavaScript or others that support <action>/<pattern>(/<substituiton>)/modifiers regex declaration. Just to avoid terminology confusion: inline modifiers (enforcing case-insensitive search, multiline, singleline, verbose and … Read more
So the way to do it is the following, httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(“Bearer”, “Your Oauth token”);
