Microsoft’s DPE team in Central and Eastern Europe (CEE) has started organizing a so called brown bag sessions for NAV developers, as a part of developing a Microsoft Dynamics Community in the region. As a part of this initiative, I will deliver a brown bag session tomorrow at 9:30 AM (CET) titled “Connecting to NAV through Web services”.

Sessions are delivered through Live Meeting and are by-invitation only, so if you want to participate you must be an employee of a Microsoft partner company in CEE region. If you haven’t got an invitation, and you are entitled to participate, please contact your local Dynamics lead at Microsoft (or Partner Account Manager) and ask them to send you the link.

If you try exposing Page 5 Currencies as a Web service in Microsoft Dynamics NAV 2009, and then consuming this web service through a .NET application, you are almost guaranteed to encounter some unhelpful and generic XML errors that give you absolutely no clue about what exactly, where and why, went wrong.

The error took me a while to debug and pinpoint the source, but in the end I managed to find a neat solution which I find worth sharing here, just in case somebody out there is scratching their had over it.
