If you work in SharePoint development you probably already have noticed that the tools are getting a new update.
With previous versions Microsoft.SharePoint.Client.Search and Microsoft.SharePoint.Client.Search.Applications dll’s were not included (it most likely has been forgotten)
You then had two solutions:
Ensure that all developers had SharePoint binaries installed on their machines
Embed a copy of the dll taken from a SharePoint machine
Both solutions were not very practical.
These dlls are now included for version 15 and 16 located here C:\Program Files\Common Files\microsoft shared\Web Server Extensions\
If you had references to a copy of the dll, when reopening the project it should be automatically updated (not always the case).
I couln’t find any official Microsoft changelog or blog about it this is why I took the time to post something.
