Not really. There's the IDisposable interface you can implement, and some language features around making it easy to use[2], however there's nothing preventing you from not using those language features and forgetting to call Dispose.

In case you forget the GC will call Dispose but it's entirely up to the GC when that happens, so personally I wouldn't say it's similar.
