Check your usage of MgMap constructor and Open/Create/Save methods.

This sounds similar to:

Hi Jackie,

Yes, its sounds similar, but i've already check these method calls.

Now the code looks like this:

MgMap map = new MgMap(siteConn);
// strMapDefinition is extracted from web layout content
MgResourceIdentifier mapDefinitionResId = new
MgResourceIdentifier(strMapDefinition);
mapName = mapDefinitionResId.GetName();

//map.Create(resourceService, mapDefinitionResId, mapName);
map.Create(mapDefinitionResId, mapName);

// set filters to some layers ...


//map.Save(resourceService, mapStateId);
map.Save();

This works well on a Windows Server 2012 or on my personal computer (Windows
8).

We moved from Windows Server 2008 R2 to Windows Server 2016 but we have an
older MapGuide version (2.1.0.4283-Final) without problems. We using AJAX
Viewer, IIS and Winforms aspx etc. The only thing we had to do was to
install the Microsoft ASP.NET 2.0 AJAX Extensions 1.0. No code changes
needed.

Hi Frieda,

Thanks for your response.
In your application, do you manipulate the MgMap and an associated WebLayout
?
It seems to me that the WebLayout doesn't take into account the created map
session.

I did more tests:

I tried to display the map created with MgMap using
GETDYNAMICMAPOVERLAYIMAGE mapagent's operation.
This map is well filtered. 

So the problem is the WebLayout.

WebLayout content looks like this:
http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xsi:noNamespaceSchemaLocation="WebLayout-2.4.0.xsd">
  
  
Library://TEST/TEST.MapDefinition
TaskPane
  
...


In Windows Server 2012, the created web layout use my created map in
session.
In Windows Server 2016, the created web layout seems to re-create a map from
specified MapDefinition.

Here are some VB Functions. Please note that this code comes from a
decompiler, because the source code is lost :/

I found the problem.
For Windows Server 2012, the mapviewernet mapframe.aspx was patched to be
able to open a Map instead of create a Map.
This is why in a new platform, the created map session was ignored.

Thanks frieda for your help.
