I was working with a Windows Phone 8.1(RT) application, I wanted to know how to get the number of files inside a StorageFolder . I know we can use StorageFolder.GetFilesAsync() and then check the count of this list returned. But since this method takes too long and returns all items is there more efficient method of getting this done? You can get 3 orders of magnitude faster performance if you use Win32 APIs to get the file count, but it only works for your local storage directory (it won't work for brokered locations such as Pictures or Music). For example, given the following C++/CX

It is now possible to share data between users of a given app in Windows 10, by

Below is a code snippet: async Task TestClientCertAuth() { int iWinInetError = 0; Uri theUri = new Uri("http://xxx-xxx"); try { using (HttpBaseProtocolFilter baseProtocolFilter = new HttpBaseProtocolFilter()) { // Task<Certificate> GetClientCertificate() displays a UI with all available // certificates with and returns the user selecter certificate. An // oversimplified implementation is included for completeness. baseProtocolFilter.ClientCertificate = await GetClientCertificate(); baseProtocolFilter
