All seem to solve the problem by setting the

问题 When I try to serve a WCF service on IIS in a Windows 8 machine, I get the well known error The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map. The old work around was to run aspnet_regiis -i but this command seems to have been deprecated in Windows 8 yielding response This option is not supported on this version of the operating system.

问题 I was able to find EventTrigger in the WinRT reference, however, I wasn't able to find DataTrigger. I wasn't able to use it in an application either.

问题 Is there any other way of checking whether a file exists in a Windows Store app? try { var file = await ApplicationData.Current.LocalFolder.GetFileAsync("Test.xml"); //no exception means file exists } catch (FileNotFoundException ex) { //find out through exception } 回答1: According to the accepted answer in this post, there is no other way at the moment.

问题 Microsoft's SmartScreen Filter under Windows 8 is a small developer's worst nightmare. While I realize the benefits to end users and the effectiveness at stopping malicious programs from installing themselves on end users' computers, I and many other developers would rather not pay the fees for annual renewal of a Code Signing Certificate or, even worse, an EV Code Signing Certificate. Also, when products developed for use in-house are signed with a trusted certificate from an internal CA,

问题 I am using a ListView in a Windows 8 Metro style app and I want to programatically make it scroll to a point where a particular item is in the view. Is this possible? 回答1: Not sure if you're working with JavaScript or XAML, but in JavaScript you should be able to just set the ensureVisible(index) property of the ListView.
