Latest nightly build 15.4.1.17042501 crashes Visual Studio on load

[saul]

@KevinRansom can this be rolled back ASAP?

ActivityLog states:

LegacySitePackage failed for package [FSharpPackage]Source: 'Microsoft.VisualStudio.Composition' Description: Expected 1 export(s) with contract name "Microsoft.VisualStudio.FSharp.Editor.SettingsPersistence+ISettings" but found 0 after applying applicable constraints.

So I cleared my ComponentModelCache, and now Visual Studio crashes when trying to load F# solutions :(

Is it after clearing cache or just after installing?
What would make it stop working out of sudden?

Can't reproduce it

The crash is after clearing the cache. The error in the ActivityLog breaks the package loading. That occurred immediately after updating to this version.

It's a shame the VS update manager doesn't let you rollback to a specific version you want to use

Also can't reproduce this anymore :/ It's auto updated again and it's working fine.
