We are working with Visual Studio 2013 and the latest SP 9 of the SDK. I noticed on install, the aspnet_client files are still installed in c:\inetpub\wwwroot. However, IISExpress in VS 2013 looks in <user>\Documents\WebSites\<SiteName> for it's global files (i.e. aspnet_client). Upon trying to view a report, the viewer then of course choked on ol' "bobj" as the files were not where it was looking.
The solution I suppose would be to copy the aspnet_client folder into each website we create, which obviously is not ideal compared to how 2010 worked (one central location in wwwroot).
Any ideas on how to have only one instance of aspnet_client? Redirect IIS Express to look where Crystal Reports installs the global files?
