- Scenario
- Writing an event handler to update a Project Workspace or Project Site URL using CSOM.
- Observed behavior
- The UpdateProjectWorkspaceAddress method, previously available in Project Server 2013, is missing or unavailable in Project Server 2016.
Ensure you have the latest administrative updates for Project Server 2016 installed and verify that your user account has central administration privileges before testing CSOM scripts.
Consult the Microsoft Q&A Project Server Forum
Because CSOM support and event handler architecture vary significantly across Project Server versions, consulting dedicated enterprise specialists is the most effective approach.
The standard Microsoft Answers forum typically lacks the specialized resources needed for complex enterprise server products like Project Server 2016. Moving your inquiry to the official developer-focused Microsoft Q&A platform ensures you connect with SharePoint and Project Server engineers.
Open your web browser and visit the official Microsoft Q&A Server forum.
Choose the 'Project Server' or 'SharePoint Server' category tags to route your question directly to enterprise experts.
Describe your issue clearly, making sure to mention that the UpdateProjectWorkspaceAddress method from 2013 is missing in 2016, and provide relevant snippets of your event handler code.

Frequently Asked Questions
Why is the UpdateProjectWorkspaceAddress method missing in Project Server 2016?
Microsoft frequently refactors server APIs between major releases. In Project Server 2016, workspace management and site architecture align more closely with SharePoint Server 2016, meaning some legacy 2013 methods have been deprecated or replaced by new CSOM approaches.
Can I use Project Server 2013 event handlers in a 2016 environment?
Directly migrating event handlers from 2013 to 2016 often results in compatibility errors. Code typically requires refactoring to accommodate updated namespaces, deprecated methods, and architectural changes in the newer server version.
Where can I find documentation for Project Server 2016 CSOM?
Official API documentation can be found on Microsoft Learn under the Project Server and SharePoint developer sections. For undocumented behaviors or missing methods, asking on the Microsoft Q&A forum is the recommended path.
