Recently i did some maintenance in a code of a colleague. I realized that he designed several classes with interface support so he do not need to protect the code blocks with try..finally to ensure that the instances are released from memory. Theoretically, which solution has higher performance? The traditional approach (code protected try..finally) or classes with interfaces (no need to protect the code. by otherside, classes with interfaces support have lock operations)?
It should be exactly the same. As soon as interfaces are used the compiler inserts an implicit try...finally in a procedure.
You can see this if you step through the code with GDB, the execution point will jump to the end of the procedure and then back to the beginning...
