<div dir="ltr">Hi Crispin,<div><br></div><div>Could you attach or send me a .mgp of the WMS feature source and its current configuration document so we have a baseline from which to determine who/what is at fault and what can be done?

I have a client with Map and MapGuide connecting to a WMS service for UK maps. AutoCAD Map makes a request OK using similar FDO WMS provider ... but the MG logs showed a InvalidCRS message when MGServer makes a map request.
I realised (via a public WMS and a helpful blog on using Fiddler) that the issue is that MG is requests always using EPSG:4326 within the Request=GetMap.
When I set my .MapDefinition up I used a British EPSG:27700 that is listed as supported in the GetCapabilities but the request does not use this native projection.
In the case of the problem service it ONLY published on EPSG:27700 and a few others and NOT on the most common EPSG:4326 – and as such returns an InvalidSRS response when MG sends it's converted request in using 4326.
A solution, obvs, is to get the provider to add the CRS into the GetCapabilities, however I think this is a bug (is there a workaround with the configuration document?) as there is no obvious requirement for this when working with projected maps and the projection is published in the WMS.
Example:
1.
Create a new WMS .FeatureSource to <a href="https://map.bgs.ac.uk/arcgis/services/BGS_Detailed_Geology/MapServer/WMSServer?service=WMS&version=1.3.0">https://map.bgs.ac.uk/arcgis/services/BGS_Detailed_Geology/MapServer/WMSServer?service=WMS&version=1.3.0</a>
1.
Create a new layer to "BGS 50k Bedrock" (a Maestro bug does not list all layers, edit XML by hand)
2.
Create a New Map, using EPSG:27700, add the layer
3.
Create a New layout and set initial view to centre on 300000,600000 and zoom scale 40000
4.
Map will preview OK but the underlying request shows similar to below
