Programmatically dehydration

Hi, we were using UserFileSystem version 4 and now we've upgraded it to version 5.
With v4 we used to call Dehydrate method, but with v5 it seems not to exists anymore. We can't find any documentation for v5 and so we don't know if the Dehydrate signature was moved or removed. Is there a way to programmatically call dehydrate on v5?
thanks.

ShellExtension with COM surrogate

Hello, we’re trying to implement a virtual file system without certificate and sparse package manifest.

Syncronization of files and folders works fine.

We are not able to implement thumbnails and context menu as seen in the sample on your web site.

As the documentation says we’re using the registration inside the main app

Then we use ShellExtensionRegistrar.Register() for Com surrogate. the only diference are two parameters tha in the doc are missing (syncrootid and log)

ShellExtensionRegistrar.Register(SyncRootId, log);

by executing the software we see that thumbnails and context menu events are not handled in out handlers.

we’ve tryed to instantiate a local server within the app and run it on background but the events still fail to be managed

can you provide us some hints or an exemple without package, sparse package manifest and certificate?
