Can you give an example of a situation where a large object is allocated in heap memory?

In C#, the allocation of a large object on the heap occurs when an object larger than 85,000 bytes is created. Such objects are placed in the Large Object Heap (LOH). For example, if you create a large array:

byte[] largeArray = new byte[100_000]; // array of size 100000 bytes

This array will be allocated in the LOH because its size exceeds the 85,000-byte threshold. The LOH is used to optimize handling large objects to reduce memory fragmentation and garbage collection overhead.
