As a few users in this thread experienced that WPF can stop working after installing VS 2008. You might see a message such as:
MissingMethodException was unhandled
Method not found: ‘System.Guid MS.Utility.EventTrace.GuidFromId(MS.Utility.EventTraceGuidId)‘.
Method not found: ‘MS.Internal.ContentType
You will experience Expression Blend or any other WPF application ceasing to launch. I found this behavior on two of my Vista machines after installing the latest VS 2008 Beta 2 bits and removing Orcas Beta 1. If I had read the “Readme” (yes, sometimes we *should* read them), I would have read that you should remove a couple of Hot Fixes prior to installing VS 2008 Beta 2.
Steps to resolve:
- Uninstall (from Programs / Features):
- Hotfix for Microsoft Windows (KB110806)
- Hotfix for Microsoft Windows (KB930264)
Hotfix for Microsoft Windows (KB929300)
