Trying to understand required members

I can't seem to set the value of a required member through a subclass's constructor. https://dotnetfiddle.net/Gz6b7M Any help is appreciated.

✅ MemoryStream question

If I have a byte[], and I'm instantiating a MemoryStream with this byte array, does it occupy twice the memory? Or is the MemoryStream simply referring to the byte array instead of copying the contents in the array?

Aggregate data grouped by a key

I'm looking to aggregate these data:

// from this
[
  new { id = 1, qty = 3 },
  new { id = 2, qty = 5 },
  new { id = 1, qty = 10 },
]

// to this
[
  new { id = 1, qty = 13 },
  new { id = 2, qty = 5 },
]

// from this
[
  new { id = 1, qty = 3 },
  new { id = 2, qty = 5 },
  new { id = 1, qty = 10 },
]

// to this
[
  new { id = 1, qty = 13 },
  new { id = 2, qty = 5 },
]

my current approach iterates over the list into a dictionary and check for duplicate keys. i have a feeling it can be done in a cleaner way with System.Linq stuff

Creating a function that accepts either string or byte[]

i have some function that is supposed to perform AES 256 encryption, EncryptAes(byte[] plaintext, byte[] key) the problem is i want this function to accept either string or byte[] but then i have to declare 3 other function overloads. So my approach was something like EncryptAes(EncryptionInput plaintext, EncryptionInput key) and then a bunch of public static implicit operators. is this a good approach?

Help me with my concurrency experiments

Correct me if I'm wrong. Based on my understanding, a CPU with 1 core running 1 thread has the same computing power as another CPU with 1 core running 2 threads. The latter will handle 2 tasks but each task will roughly have half of the computing power. Is there anything in C# I can do to simulate this? Perhaps a function that exits after a certain amount of CPU cycles.
