Editor's Notes
- Good resource: http://msdn.microsoft.com/en-us/library/fp142385.aspx
- Client-Side OMKinda-like SOM3 Versions.NetJSSilverlightREST/ODataStandards-basedOpen to anyoneWidely known
- Demo Reminder Script:Explain ListData.svcvsClient.svcOpen browser to listdata.svcShow lists -> one list -> one list item -> one field (CreatedBy)Show Query - $filter=StartsWith(Title,’[X]’)Show SelectShow OrderByShow Fiddler (JSON - application/json;odata=verbose)Show Client.svc/_vti_bin/client.svc -> /_api_api/web/getAvailableWebTemplates(1033)_api/social.following/my/Followed(types=4)C# Proxy - uses “LINQ TO WCF Data Services”Generating proxyWhere,OrderByJS Example – basic, then more complex
- Client-Side OMKinda-like SOM3 Versions.NetJSSilverlightREST/ODataStandards-basedOpen to anyoneWidely known
- Good:MUCH larger footprint, ESPECIALLY for REST service More MS Investment? One less “moving part”? New API for WPhoneBad: Not like-for-like (CSOM still does more, like Taxonomy fields) Less “RESTful” no $metadata (for now?) NO LONGER STANDARDS COMPLIANT!

- But sometimes, nothing beats knowing how to use something properly…
- Limit RowsLimit ColumnsSome effectsLimit CallsCaching (do your own)“Expand”BatchingFool the UserAsync
- (Can be tunneled in POST commands)
- Uses “Etags”
- ConcurrencyMERGE vs. PUT
- Joke slide – nothing of value here
