By now Iâ€™m assuming most of you have downloaded and installed Service Pack 1 for Visual Studio 2008. For those who havenâ€™t hereâ€™s a few links you may want to note:
If youâ€™ve installed any hot fixes over the last few months you should clean them up first
(note: this replaces the original Hotfix Cleanup utility for removing KB944899)
Service Pack 1
.NET Framework 3.5 Service Pack 1 (note: this is included in the Visual Studio SP1 so you only need to download this for patching servers and non-Dev client machines).
After installing â€“ VSTO problems
Something to note – a few things might go funny if you have any VSTO add-ins.
Iâ€™ve got a number of Outlook add-ins that Iâ€™ve been working on and when I started Outlook (after installing SP1) it would hang. Starting in Safe mode and then setting the Add-ins Inactive, allowed me to narrow it down to the offending modules. Some were fine, others caused problems.
(To get to this dialog in Outlook go â€“> Tools â€“> Trust Center â€“> Add-ins. Click on the Goâ€¦ button at the bottom to set modules inactive)
Fixing the issue â€“ just Rebuild
All that was required was a simple rebuild of the solutions and they are working fine again in Outlook.
