Prefer passing IDbTransaction to methods that permit it.

[amanda-mitchell]

A couple of possible variations:

When an IDbTransaction is in scope, find all methods that could be called with the IDbTransaction (but aren't) and flag them as errors. Create a code fix provider that calls the appropriate overload.

When an IDbTransaction is in scope, find all methods that accept an IDbConnection, and flag them as errors if the IDbTransaction is not passed to them. Create one code fix provider that attempts to call an appropriate overload, and another code fix provider that adds a parameter to the target method if there isn't an appropriate overload.
