Based on the developer-friendly implementation of an encoder and decoder for AS-WBXML I just build it with a small sample implementing GAL search.

If you have followed the “building blocks” series you will have noticed that I have done the AS-WBXML by hand. This approach clearly doesn’t scale, and will not work outside these constrained snippets intended for learning. And it makes for sample apps that are only able to serve up a very specific purpose. (Now, the sample code is meant for copying and pasting so that’s pretty much by design anyways.) Not to mention it has made me look lazy for not doing things properly

Clearly we would be a significant step further if we didn’t have to create the web requests by looking up values in code pages and type in each individual byte. So, how about we take it to that very next level of Exchange ActiveSync “hacking”?

We go through how we can build a utility for encoding and decoding ASWBXML so you can copy & paste XML samples from the MSDN library and test against your Exchange Server.
