.NET code in Flash export (3.5 beta)

When trying to export to Flash using the 3.5 beta (3.5.0b6 to be exact), there are some SWF export problems, that seem to point to the fact that only a subset of .NET is implemented in AS3, so some of the methods are undefined.

The errors are of the kind:

Error building Player: Exception: Compiling SWF Failed:
(...)
Call to a possibly undefined method (...) through a reference with static type (...)

The undefined methods are all String and List operations, and all the XML (XmlDocument and such).

Are these not supported because only a specific version of the .NET runtime is targeted? Maybe for this beta only a subset of .NET is implemented, but it will all be implemented in time?

The Unity folks did specifically say earlier this year that only a subset of .NET and Unity functionality (e.g. no Networking) will be in place to start. I don't remember the exact wording, but something along the lines of "we're starting with the most common features and expanding support later."

There's a full list of supported and unsupported features linked from the 3.5 release notes:
