I'm trying to use last GFAPI version (4.11.519.358).
Connection works, but when i try to request something (historical data, real time subscriprion, search for a contract) i have a disconnection from your side (the event "Disconnected" is raised).

Below the error message details. Any idea?

Reason = SocketError (0)
Exception = "Expected TopMsgTypeTagAttribute"

StackTrace = " in GF.ProtoSharp.Serialization.DeserializeMsg.DeserializeTopMsg[TBase](Func`2 getTypeFromTag, MessageReader msgReader) in GF.Api.Impl.Connection.ConnectProtoClient.c__DisplayClass0_0`2.b__0(Byte[] bytes) in LanguageExt.Option`1.Map[B]...

The problem seems to occur only with older versions of Visual Studio 2013/2015.
Using for example Visual Studio 2019 everything works.
