Hi. In EPiServer CMS 4.61 i used the IFastFileDownload for some purposes. When I try to do the same in EPiServer CMS 5.1 I get an InvalidCastException. Unable to cast object of type 'EPiServer.Web.Hosting.VirtualPathVersioningProvider' to type 'EPiServer.Web.Hosting.Versioning.IFastFileDownload'. Is it not possible do this in EPiServer CMS 5.1? If it is possible, how do I do it?


EPiServer CMS 4.61:
string path = "/demo/myfolder/mytext.txt";
UnifiedFile file = UnifiedFileSystem.GetFile(path);
IFastFileDownload filedownload = (IFastFileDownload)file.Provider;

EPiServer CMS 5.1:
string path = "/demo/myfolder/mytext.txt";
UnifiedFile file = HostingEnvironment.VirtualPathProvider.GetFile(path) as UnifiedFile;
IFastFileDownload picdownload = (IFastFileDownload) file.Provider;

string localPath = file.LocalPath;

..will get you the same value so there is no reason to use IFastFileDownload anymore. Be aware that a unified file implementation that does not provive a local path may return a Null value here (the same way a provider was not required to return a IFastFileDownload).
