问题 Was just wondering how I would go about letting the user resize a TextBox control at runtime by dragging its corners in Windows Store App. Less importantly, is the same technique used for the resizing of all controls?

问题 I would like to list blobs in a container. For desktop apps, the Azure Storage SDK provides the following method: CloudBlobContainer container = blobClient.GetContainerReference("myBlob"); container.ListBlobs(); However, using the WinRT library the method is absent (probably due to its blocking nature). What should I use instead? 回答1: You would need to use ListBlobsSegmentedAsync function on the blob container to fetch the list of blobs. See the code below for example: CloudStorageAccount
