Here is a concise answer to the interview question "Explain when to use Finalize vs Dispose in C#":
Use the Dispose method when you need to explicitly free unmanaged resources held by an object, such as file handles, database connections, or native resources[1][2][3]. Dispose should be called by the consumer of the object when they are done using it[1][4]. Implementing Dispose allows you to take advantage of the using statement to ensure Dispose is always called[4].
Use the Finalize (destructor) method as a last resort to free unmanaged resources if Dispose was not called[1][2][3]. The garbage collector will call Finalize when the object is about to be collected, but this is non-deterministic and Finalize is slower than Dispose[2][3][5].
It is recommended to implement both Dispose and Finalize together us...
