                                    I am trying to build the solution and getting following error for almost all the devX control.

                                    Error 29 Unable to resolve type 'DevExpress.Web.ASPxCallback.ASPxCallback, DevExpress.Web.v12.1, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a' C:\FirstScript\Application-W785\DMEPlus_DevX\DMEPlus\DMEPlus\Properties\licenses.licx 2 DMEPlus

                                    In my GAC (assembly folder) the version I have installed is but other developers have version Is the version conflict creating issue? What I need to do to resolve it?

                                Hello Jignesh,

                                Yes, all the applications should reference assemblies which are available in the GAC (i.e. the DXperience version should be the same).
                                It is necessary to either:
                                - Upgrade all the applications to the installed DXperience version via the Project Converter tool;
                                - Copy different assemblies (which are not installed in the GAC but used by an application) onto the application Bin folder.
