Anyone know where I can download the SharePoint 2010 SDK. I'm particularly after the SharePoint 2010 Microsoft.SharePoint.Client.Search.dll. Looks like Microsoft have removed downloads for it. Thanks
SharePoint 2010 Client object model SDK only has 2 dlls , it deos not have support for search. To access search functionality of SP 2010 from client application you have to rely on search.asmx service.
You can download it from here.. https://www.nuget.org/packages/Microsoft.SharePoint.Client/
Microsoft.SharePoint.Client.Search.dll is supported only from SP 2013
you can download that SP2013 version from below.
