You could have the problem that .Net emits an utf-8 byte-order-marker
To counter this, explicitly create an encoding instance:
System.Text.Encoding enc = new System.Text.UTF8Encoding(false);
Then implement a xml writer, or manually convert the xml to bytes, using
FYI, the MaestroAPI is LGPL, and so you may use it as a library, even
for commercial applications,
and it handles this quirk and others.

> Dear all,
> I have created programmatically a map (and its layout) using MG .Net web
> After creation, the new map and layout are visible in MG Maestro, and using
> the 'Show in browser" button are correctly shown in browser.
> The problem happens when I load the map directly from browser, and the

> PublicKeyToken=null' is not marked as serializable >>.
> Then, simply saving the new layout from MG Maestro (without any
> modification), and reloading the map directly from browser, the error
> disappears and the map is correctly shown.
> After saving the layout, there aren't differences in map and layout XML
> Have you any idea about?
> Thank you in advance.
