In his last article David Anson posted the code for VirtualFileDataObject, an easy-to-use implementation of virtual files for .NET and WPF, and now he has made a little improvement that he decided to share with you.
If you read my previous post, you may recall there was an issue with the last scenario of the sample: the application became unresponsive while data for the virtual file was downloading from the web. While this unresponsiveness won't be a noticeable for scenarios involving local data, scenarios that create large files or hit the network are at risk. Well, it's time to find a solution!
