The compression result differs between .NET Framework and .NET Core. Is it expected? Are there any knobs that can be used to remove the differences?
The following program prints different output:
var text = "\r\nusing System;\r\n\r\nclass C\r\n{\r\n public static void Main()\r\n {\r\n Console.WriteLine();\r\n }\r\n}\r\n";
var compressedStream = new MemoryStream();
using (var deflater = new DeflateStream(compressedStream, CompressionLevel.Optimal, leaveOpen: true))
using (var writer = new StreamWriter(deflater, Encoding.UTF8, bufferSize: 1024, leaveOpen: true))
{
writer.Write(text);
}
compressedStream.Position = 0;
Console.WriteLine(BitConverter.ToString(compressedStream.ToArray()));Full Framework:

Both blobs decompress back to the same value. But their compressed lengths are different.
