Just saw a cool piece of tooling that shipped with the BT Services CTP yesterday.

It allows you to copy a piece of example XML to the clipboard.

Then go Edit > Paste XML as Serializable Type

It then infers schema and does an xsd.exe all under the hoods and pastes in a serializabl .NET type.

It's a batch file in the tooling directory.

So to get it RIGHT NOW go and grab the Biztalk Service SDK.

This SDK is Biztalk in name only.... it's a far more broadly applicable to general distributed .NET development.... This is definitely something you should be downloading if you do WCF dev.
