It complicates the management of memory and can lead to unforeseen escape road issues.

One major drawback of finalize() is that you don’t have control over when (or even if) it gets executed. It depends on the GC, so resource cleanup becomes non-deterministic.

Also, objects with a finalizer survive at least one extra GC cycle, which impacts performance and memory usage. In high-load applications, that can become noticeable.

That’s why implementing IDisposable and using using statements is generally the recommended approach for managing unmanaged resources.

The finalize() method is also prone to security and reliability risks. Because it can resurrect objects melon playground (by making them reachable again), it complicates memory management and may cause unexpected behavior. Additionally, exceptions thrown inside finalize() are ignored, making debugging difficult.

Good reminder. Finalizers are costly and unpredictable, while Dispose gives you control and better performance.

We should avoid writing a Finalize method (destructor) unless our object controls some unmanaged resource (such as file handles, window handles, or database connections) other than managed memory. If our object merely has references to other managed code objects, garbage collector will take care of freeing all the memory and other objects correctly.

The reason to avoid finalizers, unless you absolutely need them, is
• Objects with finalizers take much longer to garbage collected than do objects without, so don't override Finalize “just to be safe.” 

• Before the object that has a finalize method can be garbage collected, CLR will do a lot of time consuming work on this. So think twice before you use the finalize method, as finalizing objects can needlessly hurt your program's performance.

• We cannot really predict when the finalize method will be called. It will be called during garbage collection, and time to collect the garbage is decided by the .net runtime by using optimization algorithms.

To surpass the disadvantage of finalizers another method is provided in .net framework i.e. Dispose. Using Dispose will not hurt your programs performance or kill the runtime time
