CloudMirror example: How to set the state of the sync root folder

[erikjv]

We have a sync provider application, and since a couple of months, the sync root status in Windows Explorer always shows "Sync pending". We use placeholders, and CfSetInSyncState to indicate if files are in sync. We also call that for the sync root.

Is there a specific call that we need to do to tell the system that a sync has started/finished? We checked the cloud mirror sample, but there is no special calls in there to do this.

I asked this question before on Microsoft Q&A, and was advised to open an issue on the github project.

This issue can be reproduced with the CloudMirror example, as described in the question linked above.
