I’ve elaborated on the T4 metadata generation idea a bit, and
published an article on it here

http://www.codeproject.com/KB/codegen/T4Metadata.aspx

The template now generates PropertyPaths for XAML bindings. This means
you get compile time validation of XAML bindings using x:Static.

It supports Silverlight and Desktop CLRs. No binding support in SL
though.
I’ve also ported the template to VB.NET.

There is experimental obfuscation support so that Expression Trees are
used to derive the property/method/field name at runtime.

Let me know what you think.

Cheers,
Daniel

Did you just say that you've started solving the XAML obfuscation problem? You hear that? It's a sound of a million developers around the world clapping for you.

Hey Mike, yes that's right. Although I wasn't convinced by its
usefulness, so I put a lid on it. But now you say lots of developers
may want it, then perhaps I should push on with it.
I use Expression trees at runtime to determine the member name when it
is requested. The result is then cached.

Cheers,
Daniel

Hey Daniel,

I am very intrigued by the T4 story. After I push my next version of the
MVVM Light toolkit, I would love to have a chat with you about this. Do you
have MSN or Skype?

Cheers,
Laurent

Would love to chat with you sometime Laurent. In fact, I've been
meaning to swing by Zurich to say hello.
I'll send you my msn privately.

Cheers,
Daniel
