Is there an equivalent to SharePoint "ensure User" in the SDK?

[Ofer-Gal]

I am planning to user this SDK but I can't find a "EnsureUser" method anywhere in the documentation.
Is there another way to get the same results.

the specific use case is to add a person to a list person field having just his email address.

Thank you much

Yep, there is EnsureUser.
