MEF Component Cache Exception

[jmessenger235]

This extension in VS pro 2015 is causing an MEF component cache exception on startup when opening a solution of 20 projects, none of which have markdown. Information on crash and configuration is below. As it stands, if the extension is enabled it causes the exception every other startup as the ones where it does not crash are on a freshly built cache. Disabling the extension resolves the issue. IIRC this was also an issue on update 2.

The exception entry from the activity log is:
