The Universal Windows Platform UWP includes many asynchronous APIs to ensure that your app remains responsive when it does work that might take an extended amount of time. This topic discusses how to use asynchronous methods from the UWP in C or Microsoft Visual Basic. Asynchronous APIs keep your app from waiting for large operations to complete before continuing execution. For example, an app that downloads info from the Internet might spend several seconds waiting for the info to arrive. If you use a synchronous method to retrieve the info, the app is blocked until the method returns. The app wont respond to user interaction and because it seems non responsive, the user might become frustrated. By providing asynchronous APIs, the UWP helps to ensure that your app stays responsive to the user when its performing long operations. Most of the asynchronous APIs in the UWP dont have synchronous counterparts, so you need to be sure to understand how to use the asynchronous APIs with C or Visual Basic in your Universal Windows Platform UWP app. Microsoft Expression is changing.

Above both sides are similar in visual weight but not mirrored. It is more casual, dynamic, and relaxed feeling so it is. Hi Brian, great work My eyes thank you English is not my first language, so I hope you understand what I say XD There is a plugin for Visual Studio 2010, called. Here we show how to call asynchronous APIs of the UWP. Using asynchronous APIs. By convention, asynchronous methods are given names that end in Async. Brandy Greatest Hits Zip. You typically call asynchronous APIs in response to a users action, such as when the user clicks a button. Calling an asynchronous method in an event handler is one of the simplest ways of using asynchronous APIs. Here we use the await operator as an example. Suppose that you have an app that lists the titles of blog posts from a certain location. The app has a Button that the user clicks to get the titles. The titles are displayed in a Text. Block. When the user clicks the button, it is important that the app remains responsive while it waits for the info from the blogs website. Zawgyi For Window 64 Bit more. To ensure this responsiveness, the UWP provides an asynchronous method, Syndication. Client. Retrieve. Feed. Async, to download the feed. The example here gets the lists of blog posts from a blog by calling the asynchronous method, Syndication. Client. Retrieve. Feed. Async, and awaiting the result. Put the keyword async on the declaration of the event handler. ButtonClick1object sender, Routed. Event. Args e. Windows. Web. Syndication. Syndication. Client client new Syndication. Client. Uri feed. Uri. new Urihttp windowsteamblog. Syndication. Feed feed await client. Retrieve. Feed. Asyncfeed. Uri. The rest of this method executes after await Retrieve. Feed. Async completes. Output. Text feed. Title. Text Environment. New. Line. foreach Syndication. Item item in feed. Items. rss. Output. Text item. Title. Torrentz will always love you. Farewell. 20032016 Torrentz. Text,. item. Published. Date. To. String Environment. New. Line. catch Exception ex. Log Error. rss. Output. Text. Im sorry, but I couldnt load the page,. Heres the error message I received. To. String. Put the keyword Async on the declaration of the event handler. Private Async Sub ButtonClick1sender As Object, e As Routed. Event. Args. Dim client As New Windows. Web. Syndication. Syndication. Client. Dim feed. Uri As New Urihttp windowsteamblog. Dim feed As Syndication. Feed Await client. Retrieve. Feed. Asyncfeed. Uri. The rest of this method executes after the await operation completes. Output. Text feed. Title. Text vb. Cr. Lf. For Each item In feed. Items. rss. Output. Text item. Title. Text, amp. Published. Date. To. String vb. Cr. Lf. Next item. Catch ex As Exception. Log Error. rss. Output. Text Im sorry, but I couldnt load the page, amp. Heres the error message I received amp. To. String. There are a couple of important things about this example. First, the line, Syndication. Feed feed await client. Retrieve. Feed. Asyncfeed. Uri uses the await operator with the call to the asynchronous method, Retrieve. Feed. Async. You can think of the await operator as telling the compiler that you are calling an asynchronous method, which causes the compiler to do some extra work so you dont have to. Next, the declaration of the event handler includes the keyword async. You must include this keyword in the method declaration of any method in which you use the await operator. In this topic, we wont go into a lot of the details of what the compiler does with the await operator, but lets examine what your app does so that it is asynchronous and responsive. Consider what happens when you use synchronous code. For example, suppose that there is a method called Syndication. Client. Retrieve. Feed that is synchronous. There is no such method, but imagine that there is. If your app included the line Syndication. Feed feed client. Retrieve. Feedfeed. Uri, instead of Syndication. Feed feed await client. Retrieve. Feed. Asyncfeed. Uri, execution of the app would stop until the return value of Retrieve. Feed is available. And while your app waits for the method to complete, it cant respond to any other events, such another Click event. That is, your app would be blocked until Retrieve. Feed returns. But if you call client. Retrieve. Feed. Async, the method initiates the retrieval and immediately returns. When you use await with Retrieve. Feed. Async, the app temporarily exits the event handler. Then it can process other events while Retrieve. Feed. Async executes asynchronously. This keeps the app responsive to the user. When Retrieve. Feed. Async completes and the Syndication. Feed is available, the app essentially reenters the event handler where it left off, after Syndication. Feed feed await client. Retrieve. Feed. Asyncfeed. Uri, and finishes the rest of the method. The nice thing about using the await operator is that the code doesnt look much different from how the code looks if you used the imaginary Retrieve. Feed method. There are ways to write asynchronous code in C or Visual Basic without the await operator, but the resulting code tends to emphasize the mechanics of executing asynchronously. This makes asynchronous code hard to write, hard to understand, and hard to maintain. By using the await operator, you get the benefits of an asynchronous app without making your code complex. Return types and results of asynchronous APIs. If you followed the link to Retrieve. Feed. Async, you might have noticed that the return type of Retrieve. Feed. Async is not a Syndication. Feed. Instead, the return type is IAsync. Operation. With. Progresslt Syndication. Feed, Retrieval. Progress. Viewed from the raw syntax, an asynchronous API returns an object that contains the result within it. While it is common, and sometimes useful, to think of an asynchronous method as being awaitable, the await operator actually operates on the methods return value, not on the method. When you apply the await operator, what you get back is the result of calling Get. Result on the object returned by the method. In the example, the Syndication. Feed is the result of Retrieve. Feed. Async. Get. Result. When you use an asynchronous method, you can examine the signature to see what youll get back after awaiting the value returned from the method. All asynchronous APIs in the UWP return one of the following types The result type of an asynchronous method is the same as the TResult type parameter. Types without a TResult dont have a result. You can think of the result as being void. In Visual Basic, a Sub procedure is equivalent to a method with a void return type.
