I upgraded the Maestro SDK to newest version, and target my Web project to .net 4.5, and recompiled it with VS2012. But I met the following error message.
InternalXmlHelper.vb(9) : error BC30560: 'ExtensionAttribute' is ambiguous in the namespace 'System.Runtime.CompilerServices'. I searched posts and found only one thread about it, writen by Jackie Ng. link on MapGuide User <http://osgeo-org.1560.n6.nabble.com/Compile-Maestro-API-in-Visual-Studio-2010-and-NET-Framework-3-5-td4183037.html> But I still can't clearly know how to deal with it. Could please help give more information.
