Expand CSOM code
Expand CSOM code base so that SharePoint Online users are able to write the same code as on prem users.
Thank you for your input, but since this is too generic statement, item is closed. We are evolving CSOM based on the specific requests and scenarios provided from customers and partners. We are releasing new version of CSOM NuGet packages on monthly basis for SharePoint Online and keep on adding missing scenarios as part of the releases.
Server side object model for SharePoint is massive and there are numerous areas which provide APIs in the farm level. Since CSOM is also used in SharePoint Online, we cannot provide this level of API reach with the CSOM side.
We are addressing gaps in the site and site collection level APIs based on your input, so would suggest to provide input on missing capabilities and to include also the actual business scenario why the API is needed. This helps on prioritizing these requests in the future.
