New Release: SharePointDsc v4.9
Published Nov 11 2021 03:51 AM 5,563 Views

With the release of SharePoint Server Subscription Edition a few weeks ago, we are focusing our attention on the v5.0 release. We are doing some final tests, making sure we can release a working version that supports SPSE. But that of course doesn't mean we aren't paying attention to the current version anymore! That is why we released v4.9 earlier this week!


This release contains fixes for several issues discovered in SharePointDsc over the past weeks. One major issue that was fixed was introduced when we released native ReverseDsc support. The issue was caused by the fact that SharePoint is still using PowerShell Snapins and was throwing the dreaded "Fixed issue where the snapin was generating the "An item with the same key has already been added" error.

In previous versions we already implemented several fixes, all with their own side effects. This time we took a different approach and we are confident that this will fix the issue once and for all.


You can find the SharePointDsc v4.9 in the PowerShell Gallery!


NOTE: We can always use additional help in making SharePointDsc even better. So if you are interested in contributing to SharePointDsc, check-out the open issues in the issue list, check-out this post in our Wiki or leave a comment on this blog post.
