I'm hoping someone can repro this, but I'm sure this is what happened on my machine.

• Created a Class library. By happenstance, closed and reopened VS
• Added FxCop rules via NuGet
• Broke one (CA1012) got the green squiggly
• Did not get margin lightbulb
• Hovered over the class name (squiggled) and got the message did not get the lightbulb popup
• Closed and reopened Visual Studio
• Still do not get margin lightbulb
• Now I do get the popup lightbulb when I hover over the squigglie

1. I expect to get a margin lightbulb because there is a fix available (changing public to protected on the constructor).

2. I expect to get the popup lightbulb without closing and reopening Visual Studio
