When it happens, you may exhaust your connection pool before that stuff gets collected. I think the creator of a disposable object is responsible for disposing of it no matter what happens, not the garbage collector. So you have basically two correct strategies: handling it yourself (in a fail-safe way) or delegating that responsiblity to the calling code by making yourself disposable. Incorrect code happens.

Failed queries shouldn't happen frequently anyway IMO because they typically are the result of incorrect code. well, if a query fails the underlying SqlCommand object will eventually be garbage collected so i wouldn’t really worry about that.

I would be a little concerned about the query failing and never getting disposed of. Another complementary idea may be to do some lifetime management from the session so that you can be sure that when the session goes away, all queries open with it do too. Am I making sense?
