update: .NET Framework Assistant (ClickOnce support) unblocked

We received confirmation from Microsoft this evening that the Framework Assistant add-on is not a mechanism for exploiting the vulnerabilities detailed in the earlier post, so we’ve removed it from the blocklist. As the blocklist update propagates to clients, the add-on should be re-enabled for users who had it previously enabled.

We’re hard at work on improving the experience for (especially enterprise) users who wish to override the blocking of the WPF plugin before we remove it from the blocklist, and I’m working on a post to clarify the events of the past few days. We (especially I) appreciate your patience and support as we work to keep our users safe and comfortable with all the tools at our disposal.
