How does .NET GC work?
NET’s garbage collector manages the allocation and release of memory for your application. Each time you create a new object, the common language runtime allocates memory for the object from the managed heap. … Eventually the garbage collector must perform a collection in order to free some memory.
What is GC heap size?
The heap can be considered as the accumulation of two heaps: the large object heap and the small object heap. The large object heap contains objects that are 85,000 bytes and larger, which are usually arrays.
What causes a memory leak?

How does Python detect memory leaks?

How does Python manage memory?
The Python memory manager manages chunks of memory called “Blocks”. A collection of blocks of the same size makes up the “Pool”.
