Does anybody know a way to get Visual Studio 2015 to work with MS CRM FetchXML connections when doing SSRS?
I'm sorry but there is no easy and supported way of doing it. Supported configurations are: The following components are required:
Microsoft Visual Studio 2012 and Microsoft SQL Server Data Tools - Business Intelligence for Visual Studio 2012 -- OR -- Visual Studio 2010 and SQL Server Data Tools
