By changing to IEnumerable, it is possible to iterate only a portion of the list, which is useful when not all entries are needed (e.g., when testing a connection).
All existing backends have been updated, and any which were able to be changed to yield return results in a straightforward way now do.
Many backends had a try/catch in the List() method. Due to the fact that yield returns can't be placed within a try/catch block, these have been refactored to either scope the try/catch to the parts that (should) be the only places throwing exceptions, so that exceptions are still caught and handled.
Note that lazy evaluation may cause some changes in behavior - exceptions that were previously thrown at the point of invokation of List() may now be thrown while it is being enumerated.
I believe this will not be problematic though, as the only well-known exception seems to be FolderMissingException, which should be thrown by Test(), but TestList() attempts to enumerate the list to force this exception.
Any places that require the legacy behavior can get it by simply converting the lazy enumerable to a List()
Now the WebRequest.Timeout property ONLY affects the GetRequestStream() and GetResponse() methods as the documentation says it SHOULD.

Previously some backends autocreated a missing folder, and some threw an exception.
The new standard is that all backends throw the FolderMissingException on all access (except delete).
This means that the Test() and List() methods are now the same for all stock backends.
Third-party applications that use the backends should implement custom logic to auto-create the folders,
when the FolderMissingException is encountered.
Duplicati auto-creates missing folders, but this can be toggled through the new flag --disable-autocreate-folders.
In case the auto-create fails to detect a missing folder, there is now a "create-folder" action in the commandline version.
Update issue #102
Status: Fixed
The IBackend_v2 interface has the CreateFolder and Test methods.
The CreateFolder is exposed to the commandline interface with the action create-folder.

This was based on the idea that the interfaces should remain static.
I hope this change is enough to ensure stable interfaces until release 1.2.
Overview of changes:
Moved all interfaces into the same dll.
Encryption and compression is now plugable modules, just as the backends.
Encryption/compression can now register an UI.
Encryption now uses AESCrypt as a default.
GPG does not default to using the --armor option.
Added support for generic modules, but none are written yet.
Added support for plugable settings pages in the "Options" dialog.
Fixed issue #148.
Duplicati now uses AESCrypt as the default encryption format.
Fixed issue #199.
GPG now supports custom commandline options.
Fixed issue #207.
Encryption modules are now plugable.
Fixed issue #118.
S3 credentials are now stored.
Fixed issue #151.

Also changed the default url behavior to use api.mosso.com as the hostname to avoid problems with container names that are not valid hostnames.

This was a timeout bug that was triggered after 100 seconds.
Also added a timeout control to the WEBDAV and FTP backends, in case they have the same bug.
Made a few string localizable in the CloudFiles backend.
Added the code to do local MD5 generation, but commented it out as there are issues with this.
Added Duplicati version string to the WEBDAV backend user agent identification.

Still needs to create a UI for it before it is avalible in the Wizard.
Added a non-seekable stream class to further improve on the reliability of the backendtester.
