# Changes on the .NET platform

Saxon is now explicitly supported on both .NET 1.1 and .NET 2.0 (previous releases were not validated on .NET 2.0, though experience showed that they ran without problems).

It is now possible to run queries and transformations directly on a DOM Document without first converting it to a Saxon tree. Instead of the `Build` method in the `DocumentBuilder`, use the new `Wrap` method. This creates a lightweight wrapper around the DOM document which makes it behave like the Saxon `NodeInfo` model. The code is very similar to the DOM wrapper used on the Java platform.

The `XdmValue` class is a wrapper for a Saxon `ValueRepresentation`. For applications that need more intimate access to the underlying Saxon objects, `XdmValue` now has `Wrap` and `Unwrap` methods that expose the underlying Java object.

The `SchemaManager` and `SchemaValidator` both now allow an `ErrorList` to be supplied, to capture error conditions encountered during schema compilation and instance document validation respectively.
