Microsoft SharePoint CSOM product availability and support when connecting to SharePoint 365

Question

Hi,

SharePoint CSOM is quite simple to setup when developing an application in csharp/.net to get data from Office 365.

For example, you can grab sharepoint DLLs and you can simple to the sharepoint site on office 365 using your credential.
or you can use NuGet to download these DLL using Microsoft.SharePointOnline.CSOM.

I would like to know what maintenance do I need to do overtime, if I choose to use SharePoint CSOM to develop my application.
Can I still use the same DLLs in 10 years time?

Do I need to keep updating these DLLs whenever SharePoint Online has a maintenance upgrade?

Regards,
Novian

Answer 1

It is unlikely that the DLLs will still be valid (or still available for a supported platform) in 10 years, but it's anyones guess. You should keep your NuGet packages updated over time, recompile and redeploy your application.

Answer 2

Hi NovianWinangun-6161,

I think it's not promised that the old version dll is still valid in 10 years, we'd suggest you keep it updated.

How can I subscribe to get notification about SharePoint online news updates?

Especially those that can break my applications?
