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.</div>

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.</div>

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.</div>
<div style="direction: ltr; font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
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.</div>

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.</div>
