Code analysis in F#

Question

As a C# developer I've benefited from Microsoft's Code Analysis. In F# however, Code Analysis doesn't seem to be an integrated part of the development cycle. It took me a while to enable CA on an F# project, but this blog helped . Now that I have CA enabled, it seems to produce "wrong" warnings. For instance, I have a declared a record type as

type Account = {Number : string}

for which I expect structural equality by default. This blog demonstrates that two instances of type Acccount, for which the number is the same, should be equal. Why does the code analysis then tell me that: 'Account' should define operator '!=' since it implements IComparable? For sure, had this been a C# class then I would have to jump through all those hoops, but in F# this should happen automagically.

I am applying the "Microsoft All Rules" ruleset. Do these not apply to F#, and if so, is there any ruleset that I should use?
