vs 2017, under my project tab for references I have the error "Could not load type 'Microsoft.VisualStudio.WCFReference.Interop.IVsServiceReferenceMetadataStorageEvents' from assembly 'Microsoft.VisualStudio.WCFReference.Interop, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'."
my project builds ok, debugs ok, and runs ok on s local IIS 10.0 site I created for the project (not vs IIS express)
I am having issues that seem related to references publishing to an external web host site via ftp, the suggestions for that appear to be to set reference to 'copylocal'. that seems a bit cumbersome, I have about 25 references to the project. there are only 2 I have added in addition to the project defaults. The external site has all the latest and greatest IIS, .net framework, etc. I would thing all the references would be there in the site GAC, as they must be in my little local IIS for the site to run ok there.
