New SharePoint CSOM version released for SharePoint Online – May 2016

Vesa Juvonen

We are happy to announce availability of new SharePoint Client Side Object Model (CSOM) version targeted for the Office 365 or more specifically for SharePoint Online. This release again contains few updates on the existing SharePoint CSOM assemblies and some maintenance changes. You can find the latest CSOM package for SharePoint online, including the Project Online CSOM assembly, from the NuGet gallery with an id of ‘Microsoft.SharePointOnline.CSOM’. We are also working on updating the redistributable package at some point, but you can already right now start using some of these new capabilities in your solutions. In general we do recommend you to use the Nuget Package to gain access on latest version, rather than downloading the SDK to your machine.

Version of the released CSOM package is 16.1.5312.1200. Previous versions of the NuGet has not been removed, so that your existing solutions will continue working without issues and you can decide when the new version is taken into use. Notice that even though the Nuget version is increased to 16.1.5312.1200, actual assembly version of the released assemblies is You can also check the version of the assemblies from the File Version attribute, which alings with the Nuget version.

Notice. If you like to operate with SharePoint Online rather using PowerShell, we are also looking to update the SharePoint Online Management Shell during upcoming days. Documentation for SharePoint Online Management Shell will be updated accordingly based on the changes in latest version.

New properties and methods cross assemblies

Here’s a raw list of all the new properties and methods in the assemblies. Notice that some of these properties and methods are meant to be used only internally, even though they are exposed in the CSOM API. This means that their usage models might not be completely straight forward and results could be unexpected. Below list contains main changes in the particular assemblies. We have filtered out those elements which are not relevant or change is minimal. MSDN library for the CSOM assemblies will be updated to match the latest version at some point and capabilities will be enabled cross tenants gradually. We’ve included high level description for some of the mentioned properties where needed.
