I'm trying to deserialize the response message from my database in protobuf format. It has this schema:
syntax = "proto3";
message Person
uint64 id = 1;
string name = 2;
string surname = 3;
uint32 age = 4;
;
and I created this class to deserialize it:
[ProtoContract]
public class Person
[ProtoMember(1)]
public long Id get; set;
[ProtoMember(2)]
public string Name get; set;
[ProtoMember(3)]
public string Surname get; set;
[ProtoMember(4)]
public int Age get; set;
Next, I tried to do this:
var response = await client.PostAsync("", new StringContent(request));
using (var responseStream = await response.Content.ReadAsStreamAsync())
var person = Serializer.Deserialize<Person>(responseStream);
But I cathed a ProtoBuf.ProtoException: Invalid wire-type;.
Then I decided to see at byte array:
25, 8, 1, 18, 6, 82, 111, 98, 101, 114, 116, 26, 11, 79, 112, 112, 101, 110, 104, 101, 105, 109, 101, 114, 32, 38
And I created by hand an entry, that must be returned by my database, and serialize it:
8, 1, 18, 6, 82, 111, 98, 101, 114, 116, 26, 11, 79, 112, 112, 101, 110, 104, 101, 105, 109, 101, 114, 32, 38
As you can see, they are almost the same, but my db send 25 at the start.
Could you help me, what could be the error?
Thanks!

I realized, that it is due to streaming multiple messages.
And in this case, I've rewritten my method to:
List<Person> persons;
using (var responseStream = await response.Content.ReadAsStreamAsync())
persons = Serializer.DeserializeItems<Person>(responseStream, PrefixStyle.Base128, 0).ToList();
