According to MSDN Magazine, you can not use managed code nor can you draw your own UI.

Regarding drawing the UI:

There has also been an important change regarding which component renders the graphical aspect of the logon. Previously, this was handled by GINA and thus a third-party component could have been doing the rendering. In the new architecture, LogonUI, which is a built-in piece of the operating system, is responsible for this.

So how is per-provider user prompting behavior achieved in the new model? The Credential Provider architecture requires each provider to enumerate its UI elements. For example, in a given scenario, a provider might indicate to LogonUI that it requires two edit boxes, two captions, a checkbox, and a bitmap. In turn, LogonUI renders those controls on behalf of the credential provider. This goes a long way toward achieving the goal discussed previously-a consistent look and approach that supports a broad set of evolving authentication scenarios.

Regarding managed code:

The credential provider architecture and its host support only native code.
