Save and Restore using DockSiteLayoutSerializer()

Hi Scott,

The layout information is match up using the Name property, so you must ensure that a DocumentWindow with the name "X07a3dea9" is registered with the DockSite before loading your layout. Otherwise it will not be use restored, unless you are using our lazy-loading feature.

I made the change, but the windows seem to still go away.  After loading the layout the documents collection is 0: LoadFromString(layout, documents);

I tried setting the DockingWindowDeserializationBehavior to Discard and AutoCreate and neither worked for me.

Here is my saved layout:

//Saved Layout.

Here is my layout before I call the LoadFromString:

Hi Scott,

If you can please put together a small sample project that reproduces your issue and email it over then we can take a closer look. Be sure to remove any executables or change the extension of the zip file to ensure it gets past our email filters.

After creating a sample project, the windows were restored to their correct location. I did not realize that the LoadFromString() closed the existing windows and recreated them. After a little digging I noticed that I had an OnDocumentClosed Event that was removing my ViewModel data when the window gets closed.
