I was use CryptoStream.Read to read bytes from a MemoryStream into a byte[]. When i'm use .Net 5 it can read all bytes but when i'm use .Net 7 it will lost some bytes. In .Net 7, when i use CryptoStream.ReadExactly it can read all bytes i need but when use CryptoStream.Read it not. Why did it happend?

If you were previously issuing a single read and getting everything back in one call, that may well not returning everything now and as Viorel mentions, you'll need to loop on the Read to get everything.
