I have installed SQL Server 2017 and Visual Studio 2013. I'm trying to create an Entry data model but it showing me this error
"Could not load file or assembly Microsoft.sqlserver.management.sdk.sfc version=11.0.0.0 culture=neutral publickeytoken".
also, I installed "Microsoft SQL Server 2017 Feature Pack".
This seems known issue, as you mentioned you have already installed Microsoft SQL Server 2017 Feature Pack https://www.microsoft.com/en-us/download/details.aspx?id=55992.
I would suggest installing Visual C++ Redistributable Packages for Visual Studio 2013 :
https://www.microsoft.com/en-us/download/details.aspx?id=40784
Close Visual Studio in installation & open after installation. In most cases restart is not required if Visual Studio & it's dependencies are not open when installation done.
Although this is old question with old version of VS & SQL but interesting read: Could not load file or assembly Microsoft.SqlServer.management.sdk.sfc version 11.0.0.0
