When does automatic memory release occur in a memory management system?

In C#, automatic memory management is handled by the garbage collector (GC). It runs in the following cases:

• When the system experiences a shortage of free memory.
• When certain memory usage thresholds are reached.
• When the GC.Collect() method is called, although manually doing this without a good reason is not recommended.

The garbage collector automatically finds objects that are no longer referenced and frees the memory they occupy. This process occurs in the background without programmer intervention.
